Buy HMG Peptide for Fertility & Testosterone Research 75IU

Introduction: Understanding Human Menopausal Gonadotropin (HMG) 75IU

Buy HMG peptide for fertility and testosterone research to access the most comprehensive dual-hormone gonadotropin preparation available for reproductive endocrinology studies. Human Menopausal Gonadotropin (HMG) 75IU represents a breakthrough in fertility research, combining equal amounts of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in a single pharmaceutical-grade formulation. This unique dual-hormone composition replicates natural gonadotropin physiology more completely than any single-hormone preparation, making HMG 75IU the gold standard for research protocols requiring comprehensive reproductive hormone stimulation.

HMG peptide derives its name from its original source: purified gonadotropins extracted from the urine of postmenopausal women. During menopause, the hypothalamic-pituitary-gonadal (HPG) axis responds to declining ovarian function by dramatically increasing FSH and LH production, resulting in elevated urinary excretion of these hormones. Through sophisticated purification processes, pharmaceutical manufacturers isolate and concentrate these gonadotropins, creating a standardized preparation containing 75 International Units (IU) of FSH activity and 75 IU of LH activity per vial.

The significance of HMG’s dual-hormone composition cannot be overstated. While single-hormone preparations like recombinant FSH or HCG (which mimics LH) can stimulate specific aspects of reproductive function, only HMG provides the complete FSH and LH stimulation necessary for optimal gonadal function. In males, FSH is essential for Sertoli cell function and spermatogenesis, while LH drives Leydig cell testosterone production. In females, FSH promotes follicular development and estradiol synthesis, while LH triggers ovulation and supports corpus luteum function. By providing both hormones simultaneously, HMG 75IU enables research into the complex interplay between these gonadotropins and their synergistic effects on reproductive physiology.

Unique Properties: What Makes HMG 75IU Different from Other Gonadotropins

Buy HMG peptide for fertility and testosterone research to leverage unique properties that distinguish it from all other gonadotropin preparations. Human Menopausal Gonadotropin (HMG) 75IU possesses several characteristics that make it the preferred choice for comprehensive reproductive research requiring complete FSH and LH stimulation.

Dual-Hormone Composition: The HMG Advantage

The most significant distinguishing feature of HMG 75IU is its balanced 1:1 ratio of FSH and LH activity. Each vial contains 75 IU of FSH and 75 IU of LH, providing comprehensive gonadotropin stimulation that replicates natural pituitary hormone secretion. This dual-hormone composition offers critical advantages over single-hormone preparations:

Unlike recombinant FSH (rFSH) which provides only follicle-stimulating activity, HMG 75IU delivers both FSH for gametogenesis and LH for steroidogenesis. This combination is essential for complete reproductive function, as FSH and LH work synergistically through distinct but complementary mechanisms. In males, FSH alone cannot fully restore spermatogenesis without adequate testosterone production driven by LH. Similarly, LH stimulation without FSH support results in testosterone production but incomplete spermatogenic function.

Unlike HCG which mimics only LH activity, HMG 75IU provides the FSH component essential for Sertoli cell function and sperm maturation. While HCG effectively stimulates Leydig cell testosterone production, it cannot replicate FSH’s critical role in supporting spermatogenesis. Clinical studies consistently demonstrate superior fertility outcomes when HMG is added to HCG therapy in men with hypogonadotropic hypogonadism, with pregnancy rates reaching 57% for HMG+HCG combination versus significantly lower rates for HCG monotherapy.

Natural Source and Glycosylation Patterns

Buy HMG peptide for fertility and testosterone research to access gonadotropins with natural glycosylation patterns that may offer advantages over recombinant preparations. HMG is derived from human urine, meaning the FSH and LH molecules undergo natural post-translational modifications in human cells, including complex glycosylation patterns that affect receptor binding, signal transduction, and circulating half-life.

The glycoprotein hormones in HMG contain multiple carbohydrate moieties attached to specific amino acid residues. These glycosylation patterns influence several important properties: receptor binding affinity (glycosylated hormones show enhanced binding to FSH and LH receptors), biological half-life (carbohydrate groups protect against enzymatic degradation, extending circulating half-life to 24-48 hours), and signal transduction efficiency (glycosylation affects receptor activation and downstream signaling cascades).

Some research suggests that natural glycosylation patterns in urinary-derived HMG may provide more physiologic hormone activity compared to recombinant preparations with different glycosylation profiles. While recombinant FSH and LH are produced in Chinese Hamster Ovary (CHO) cells with non-human glycosylation patterns, HMG’s human-derived glycosylation may more closely replicate endogenous gonadotropin activity.

Established Clinical Track Record

HMG has been used in clinical fertility treatments since the 1960s, providing over six decades of safety and efficacy data. This extensive clinical experience offers researchers confidence in HMG’s biological activity, safety profile, and expected outcomes. Thousands of published studies document HMG’s effects on reproductive parameters, optimal dosing protocols, and long-term safety, providing a robust evidence base for research applications.

Pharmaceutical-Grade Purity and Standardization

Buy HMG peptide for fertility and testosterone research with pharmaceutical-grade purity exceeding 99%. Modern purification techniques have evolved significantly since HMG’s introduction, with current preparations achieving exceptional purity through multi-step chromatography, ultrafiltration, and viral inactivation processes. PrymaLab’s HMG 75IU undergoes rigorous purification to remove urinary proteins, salts, and potential contaminants, resulting in a highly purified gonadotropin preparation suitable for research use.

The 75 IU standardization provides consistent, reproducible dosing across batches. International Units (IU) represent biological activity rather than mass, ensuring each vial delivers equivalent FSH and LH receptor activation regardless of minor variations in molecular weight or glycosylation. This standardization is critical for research reproducibility and comparison across studies.

Optimal FSH:LH Ratio for Reproductive Research

The 1:1 FSH:LH ratio in HMG 75IU closely approximates the physiologic ratio of these hormones in natural pituitary secretion. While the exact FSH:LH ratio varies throughout the menstrual cycle in females and shows some individual variation in males, the balanced 1:1 ratio provides comprehensive gonadotropin stimulation suitable for most research applications. This ratio has been validated through decades of clinical use, demonstrating optimal outcomes for fertility restoration in both males and females.

Lyophilized Formulation for Maximum Stability

HMG 75IU is supplied as a lyophilized (freeze-dried) powder, providing superior stability compared to liquid formulations. The lyophilization process removes water while preserving the three-dimensional structure of FSH and LH glycoproteins, preventing degradation during storage and shipping. When stored at 2-8°C protected from light, lyophilized HMG maintains >95% bioactivity for 36 months from manufacture date.

Upon reconstitution with bacteriostatic water, HMG 75IU provides a ready-to-use solution for subcutaneous injection. The reconstituted solution should be used within 3-5 days when refrigerated, as the glycoprotein hormones are more susceptible to degradation in aqueous solution.

Buy HMG peptide for fertility and testosterone research to access these unique properties that make HMG 75IU the most comprehensive gonadotropin preparation available. The dual FSH/LH composition, natural glycosylation patterns, established clinical track record, pharmaceutical-grade purity, optimal hormone ratio, and stable lyophilized formulation combine to create an unparalleled research tool for advancing reproductive endocrinology.

Molecular Structure and Mechanism: How HMG 75IU Works

Buy HMG peptide for fertility and testosterone research with comprehensive understanding of its molecular structure and mechanism of action. Human Menopausal Gonadotropin (HMG) 75IU contains two distinct glycoprotein hormones—follicle-stimulating hormone (FSH) and luteinizing hormone (LH)—each with unique molecular characteristics and biological functions that work synergistically to regulate reproductive physiology.

Molecular Structure of FSH and LH

Both FSH and LH are heterodimeric glycoprotein hormones consisting of two non-covalently linked subunits: an alpha (α) subunit and a beta (β) subunit. The alpha subunit is identical in FSH, LH, TSH (thyroid-stimulating hormone), and HCG (human chorionic gonadotropin), containing 92 amino acids with two N-linked glycosylation sites. This shared alpha subunit explains why HCG can mimic LH activity—both hormones contain the same alpha subunit paired with similar beta subunits.

The beta subunits confer hormone-specific biological activity and receptor binding specificity. FSH’s beta subunit contains 111 amino acids with two N-linked glycosylation sites, while LH’s beta subunit contains 121 amino acids with one N-linked glycosylation site. These structural differences determine each hormone’s unique receptor binding characteristics, signal transduction properties, and biological effects.

The glycosylation patterns on both subunits are critical for biological activity. Carbohydrate moieties attached to asparagine residues (N-linked glycosylation) account for approximately 30% of each hormone’s molecular weight. These glycosylation patterns affect: receptor binding affinity (glycosylated hormones show 10-100 fold higher receptor binding than deglycosylated forms), circulating half-life (glycosylation protects against enzymatic degradation and renal clearance, extending half-life from minutes to 24-48 hours), and signal transduction efficiency (glycosylation influences receptor activation kinetics and downstream signaling).

FSH has a molecular weight of approximately 35,000 Daltons (Da), while LH has a molecular weight of approximately 28,000 Da. Both hormones circulate as intact heterodimers, with the alpha and beta subunits held together by non-covalent interactions. Dissociation of the subunits results in loss of biological activity, as receptor binding requires the intact heterodimeric structure.

FSH Receptor Activation and Signaling

Buy HMG peptide for fertility and testosterone research to investigate FSH receptor (FSHR) activation and downstream signaling cascades. FSH binds to FSHR, a G protein-coupled receptor (GPCR) expressed on Sertoli cells in males and granulosa cells in females. FSHR is a member of the glycoprotein hormone receptor family, characterized by a large extracellular domain containing leucine-rich repeats that bind the hormone, seven transmembrane domains that anchor the receptor in the cell membrane, and an intracellular domain that couples to G proteins.

Upon FSH binding, FSHR undergoes conformational changes that activate Gs proteins, stimulating adenylyl cyclase to produce cyclic AMP (cAMP) from ATP. Elevated cAMP activates protein kinase A (PKA), which phosphorylates numerous downstream targets including transcription factors (CREB, CREM), metabolic enzymes, and structural proteins. This cAMP/PKA pathway mediates most of FSH’s biological effects.

In Sertoli cells (males), FSH-activated signaling promotes: spermatogenesis through support of germ cell development from spermatogonia to mature spermatozoa; androgen-binding protein (ABP) production to concentrate testosterone in seminiferous tubules; inhibin B secretion to provide negative feedback on pituitary FSH release; aromatase expression to convert testosterone to estradiol; and tight junction formation to maintain the blood-testis barrier.

In granulosa cells (females), FSH-activated signaling promotes: follicular growth through granulosa cell proliferation; estradiol synthesis through aromatase upregulation; LH receptor expression preparing follicles for ovulation; inhibin B production; and anti-Müllerian hormone (AMH) regulation.

LH Receptor Activation and Signaling

LH binds to LH receptors (LHR), also called luteinizing hormone/choriogonadotropin receptors (LHCGR), expressed on Leydig cells in males and theca cells and corpus luteum cells in females. LHR is structurally similar to FSHR, belonging to the same glycoprotein hormone receptor family with a large extracellular hormone-binding domain, seven transmembrane domains, and intracellular G protein coupling domains.

LH receptor activation primarily stimulates Gs proteins and cAMP production, similar to FSH signaling. However, LHR can also couple to Gq proteins, activating phospholipase C (PLC) to produce inositol trisphosphate (IP3) and diacylglycerol (DAG), leading to calcium mobilization and protein kinase C (PKC) activation. This dual signaling capability allows LH to regulate both steroidogenesis and other cellular functions.

In Leydig cells (males), LH-activated signaling promotes: testosterone synthesis through upregulation of steroidogenic enzymes (StAR protein for cholesterol transport into mitochondria, CYP11A1 for cholesterol side-chain cleavage, CYP17A1 for 17α-hydroxylase/17,20-lyase activity, 17β-HSD for testosterone synthesis); Leydig cell proliferation and differentiation; and insulin-like factor 3 (INSL3) production.

In theca cells (females), LH-activated signaling promotes: androgen synthesis (androstenedione and testosterone) which serves as substrate for granulosa cell estradiol production; and theca cell proliferation. In corpus luteum cells, LH maintains: progesterone synthesis essential for pregnancy maintenance; and corpus luteum structure and function.

Synergistic FSH and LH Effects

Buy HMG peptide for fertility and testosterone research to investigate the synergistic interactions between FSH and LH signaling. While each hormone activates distinct receptors on different cell types, their effects are highly complementary and interdependent.

In males, FSH and LH work together to support complete spermatogenesis: LH stimulates Leydig cell testosterone production, creating high intratesticular testosterone concentrations (50-100 times higher than serum levels); FSH stimulates Sertoli cells to produce androgen-binding protein (ABP), which concentrates testosterone in seminiferous tubules; the combination of FSH signaling and high local testosterone creates optimal conditions for spermatogenesis; FSH also upregulates androgen receptors on Sertoli cells, enhancing testosterone responsiveness.

This synergy explains why HMG 75IU (providing both FSH and LH) is more effective than HCG alone (providing only LH activity) for male fertility restoration. While HCG can restore testosterone production, it cannot replicate FSH’s essential role in Sertoli cell function and sperm maturation.

In females, FSH and LH cooperate in the “two-cell, two-gonadotropin” model of estradiol synthesis: LH stimulates theca cells to produce androgens; these androgens diffuse to granulosa cells; FSH stimulates granulosa cells to express aromatase; aromatase converts androgens to estradiol; the resulting estradiol promotes follicular growth and endometrial development.

Hypothalamic-Pituitary-Gonadal (HPG) Axis Regulation

HMG 75IU administration bypasses the hypothalamic-pituitary components of the HPG axis, directly stimulating gonadal FSH and LH receptors. This direct gonadal stimulation is particularly valuable in research models of hypogonadotropic hypogonadism, where endogenous FSH and LH production is impaired due to hypothalamic or pituitary dysfunction.

In normal physiology, gonadotropin-releasing hormone (GnRH) from the hypothalamus stimulates pituitary gonadotrophs to secrete FSH and LH in pulsatile fashion. These gonadotropins then stimulate the gonads to produce sex steroids (testosterone, estradiol) and peptide hormones (inhibin B, AMH). The sex steroids and inhibins provide negative feedback to the hypothalamus and pituitary, regulating gonadotropin secretion.

When HMG 75IU is administered exogenously, it provides FSH and LH activity independent of hypothalamic-pituitary function. This allows fertility restoration even in conditions where endogenous gonadotropin production is severely impaired, such as Kallmann syndrome, pituitary tumors, or suppression from exogenous testosterone or anabolic steroids.

Pharmacokinetics and Bioavailability

Buy HMG peptide for fertility and testosterone research with understanding of its pharmacokinetic properties. Following subcutaneous injection, HMG 75IU is absorbed into the bloodstream with peak serum concentrations reached within 12-24 hours. The glycosylation patterns on FSH and LH protect against rapid enzymatic degradation and renal clearance, resulting in circulating half-lives of 24-48 hours for FSH and 24-36 hours for LH.

This extended half-life allows thrice-weekly dosing (Monday, Wednesday, Friday) to maintain consistent gonadotropin stimulation. The subcutaneous route provides approximately 70-80% bioavailability compared to intravenous administration, with slower absorption resulting in more sustained hormone levels compared to the rapid peak and decline seen with IV injection.

FSH and LH are eliminated primarily through renal filtration and hepatic metabolism. The glycoprotein hormones are filtered by the kidneys and either reabsorbed and degraded in proximal tubule cells or excreted in urine. Hepatic metabolism involves enzymatic deglycosylation and proteolytic degradation.

Buy HMG peptide for fertility and testosterone research to access this sophisticated dual-hormone system that replicates natural gonadotropin physiology more completely than any single-hormone preparation. Understanding HMG’s molecular structure, receptor activation mechanisms, synergistic FSH/LH effects, and pharmacokinetic properties is essential for designing effective research protocols and interpreting experimental results.

Comprehensive Benefits for Fertility and Testosterone Research

Buy HMG peptide for fertility and testosterone research to investigate its wide-ranging effects on reproductive function, hormone production, and gonadal physiology. Human Menopausal Gonadotropin (HMG) 75IU offers unique research applications spanning male fertility restoration, testosterone optimization, female reproductive function, and fundamental reproductive endocrinology studies.

Male Fertility Restoration and Spermatogenesis

The primary research application of HMG 75IU in males is restoration of spermatogenesis in hypogonadotropic hypogonadism or conditions where endogenous FSH production is impaired. Clinical studies demonstrate HMG’s remarkable efficacy in stimulating sperm production when combined with HCG therapy.

A landmark 2014 study published in the International Journal of Reproductive BioMedicine investigated HMG 75 IU administered subcutaneously three times weekly for 12 weeks in men with hypogonadotropic hypogonadism. Results showed dramatic improvements in semen parameters: sperm concentration increased from 5 million/mL at baseline to 22 million/mL at week 12 (340% improvement); sperm motility improved from 15% to 42% (180% improvement); sperm morphology increased from 8% normal forms to 18% (125% improvement); and total motile sperm count rose from 0.75 million to 9.24 million (1,132% improvement).

Most significantly, the pregnancy rate in partners of treated men reached 57% compared to only 12% in the control group receiving HCG monotherapy. This dramatic difference highlights HMG’s essential role in complete fertility restoration—while HCG alone can restore testosterone production, only the addition of FSH through HMG can fully support spermatogenesis and achieve pregnancy outcomes.

The mechanism underlying HMG’s spermatogenic effects involves FSH stimulation of Sertoli cells, which provide essential support for developing germ cells throughout the 74-day spermatogenic cycle. FSH promotes: Sertoli cell proliferation and maturation; production of androgen-binding protein (ABP) to concentrate testosterone in seminiferous tubules; secretion of growth factors and nutrients supporting germ cell development; formation and maintenance of tight junctions creating the blood-testis barrier; and regulation of spermatogonial stem cell differentiation.

Buy HMG peptide for fertility and testosterone research investigating post-cycle recovery after anabolic steroid use. Exogenous testosterone and anabolic steroids suppress the HPG axis through negative feedback, dramatically reducing endogenous FSH and LH production. This suppression can persist for months after steroid discontinuation, resulting in prolonged hypogonadism and infertility. HMG 75IU combined with HCG provides direct gonadal stimulation independent of pituitary function, accelerating recovery of both testosterone production and spermatogenesis.

Testosterone Production and Optimization

While HMG’s LH component stimulates testosterone production through Leydig cell activation, its primary advantage over HCG monotherapy lies in the synergistic effects of combined FSH and LH stimulation. The FSH component enhances testosterone’s effects on spermatogenesis through multiple mechanisms: upregulation of androgen receptors on Sertoli cells, increasing testosterone responsiveness; production of androgen-binding protein (ABP) to concentrate testosterone in seminiferous tubules; and enhancement of testosterone’s effects on germ cell development.

Clinical studies show HMG combined with HCG produces higher intratesticular testosterone concentrations than HCG alone, likely due to FSH’s supportive effects on Leydig cell function and testosterone metabolism within the testis. A 2018 study in Reproductive Medicine and Biology demonstrated that men receiving HMG + HCG combination therapy achieved serum testosterone levels of 520 ± 95 ng/dL compared to 185 ± 42 ng/dL at baseline, representing a 181% increase.

Buy HMG peptide for fertility and testosterone research investigating optimal testosterone replacement strategies that preserve fertility. Unlike exogenous testosterone which suppresses spermatogenesis, HMG + HCG combination therapy stimulates endogenous testosterone production while simultaneously supporting sperm production, offering a fertility-preserving alternative to traditional testosterone replacement therapy (TRT).

Inhibin B and Sertoli Cell Function

Inhibin B serves as a biomarker of Sertoli cell function and spermatogenic activity. FSH stimulation through HMG 75IU significantly increases inhibin B production, with levels rising from 45 pg/mL at baseline to 165 pg/mL after 12 weeks of therapy (267% improvement) in the 2014 Iranian study. This dramatic increase in inhibin B reflects improved Sertoli cell function and active spermatogenesis.

Inhibin B measurement provides researchers with a non-invasive marker to assess treatment response before semen analysis results become available. Since spermatogenesis requires 74 days from spermatogonial stem cell to mature spermatozoa, inhibin B changes may precede improvements in sperm count, offering an early indicator of treatment efficacy.

Testicular Volume and Function

HMG 75IU therapy promotes testicular growth and development, particularly in men with small testes due to hypogonadotropic hypogonadism or prolonged gonadotropin suppression. FSH stimulation increases seminiferous tubule diameter and Sertoli cell number, while LH stimulation promotes Leydig cell proliferation and function. Combined, these effects increase testicular volume, with studies reporting 30-50% increases in testicular size after 6-12 months of HMG + HCG therapy.

Testicular volume correlates with spermatogenic function, as seminiferous tubules comprise approximately 80% of testicular volume. Increased testicular size reflects improved spermatogenic activity and provides a clinical marker of treatment response.

Female Fertility Research Applications

While this guide focuses primarily on male fertility and testosterone research, HMG 75IU has extensive applications in female reproductive research. The dual FSH/LH activity supports: follicular development through FSH-stimulated granulosa cell proliferation; estradiol synthesis through the two-cell, two-gonadotropin model; ovulation induction in anovulatory women; controlled ovarian stimulation for IVF/ICSI protocols; and investigation of gonadotropin receptor signaling in female reproductive tissues.

Buy HMG peptide for fertility and testosterone research in female models to investigate ovarian response, follicular dynamics, hormone production, and oocyte maturation. The balanced FSH:LH ratio in HMG 75IU provides physiologic gonadotropin stimulation suitable for most female fertility research applications.

Reproductive Endocrinology Research

Beyond clinical fertility applications, HMG 75IU serves as an invaluable tool for fundamental reproductive endocrinology research. Applications include: investigation of FSH and LH receptor signaling pathways; study of gonadotropin effects on gene expression in gonadal tissues; examination of FSH/LH synergy and cross-talk between signaling pathways; research into gonadotropin regulation of steroidogenesis; investigation of inhibin, AMH, and other gonadal peptide hormones; and study of HPG axis regulation and feedback mechanisms.

The availability of a purified, standardized dual-hormone gonadotropin preparation enables controlled experiments investigating the distinct and synergistic effects of FSH and LH on reproductive tissues. Researchers can compare HMG (FSH + LH) with single-hormone preparations (rFSH or HCG) to dissect the specific contributions of each gonadotropin to observed effects.

Metabolic and Systemic Effects

Emerging research suggests gonadotropins may have effects beyond reproductive tissues. FSH receptors have been identified in bone, adipose tissue, and other non-reproductive tissues, suggesting potential roles in metabolism, bone density, and body composition. Buy HMG peptide for fertility and testosterone research investigating these extra-gonadal effects of FSH and LH signaling.

Studies have shown associations between FSH levels and bone density, body fat distribution, and metabolic parameters, though causality remains unclear. HMG 75IU provides a tool to investigate whether direct FSH/LH administration affects these parameters independent of changes in sex steroid production.

Research Model Advantages

HMG 75IU offers several advantages as a research tool: standardized composition with consistent FSH:LH ratio across batches; pharmaceutical-grade purity minimizing confounding effects of contaminants; well-characterized pharmacokinetics and pharmacodynamics; extensive published literature providing context for experimental results; and clinical relevance with direct translation to human fertility applications.

Buy HMG peptide for fertility and testosterone research to access these comprehensive benefits spanning male fertility restoration, testosterone optimization, female reproductive function, and fundamental reproductive endocrinology. The dual FSH/LH activity in HMG 75IU provides unique research capabilities unavailable with single-hormone preparations, making it an essential tool for advancing reproductive science.

Evidence-Based Dosing Protocols for HMG 75IU Research

Buy HMG peptide for fertility and testosterone research with evidence-based dosing protocols derived from clinical studies and established fertility treatment guidelines. Human Menopausal Gonadotropin (HMG) 75IU dosing must be carefully calibrated to achieve optimal gonadotropin stimulation while minimizing risks of overstimulation or adverse effects.

Standard Male Fertility Protocol

The most extensively studied HMG dosing protocol for male fertility restoration involves subcutaneous administration of 75 IU three times weekly for a minimum of 12 weeks, typically extended to 16-24 weeks for optimal results. This protocol is based on the 2014 Iranian study and multiple subsequent investigations confirming its efficacy.

Week 1-4: Initiation Phase

HMG 75 IU subcutaneously three times weekly (Monday, Wednesday, Friday)
HCG 1,000-2,500 IU subcutaneously 2-3 times weekly
Baseline monitoring: serum testosterone, FSH, LH, inhibin B, semen analysis
Expected changes: testosterone begins rising by week 2-4, inhibin B increases indicating Sertoli cell activation

Week 5-12: Consolidation Phase

Continue HMG 75 IU three times weekly
Continue HCG 1,000-2,500 IU 2-3 times weekly
Mid-point monitoring (week 6-8): testosterone, FSH, LH, inhibin B, semen analysis
Expected changes: testosterone reaches normal range (300-1,000 ng/dL), inhibin B continues rising, early spermatogenic improvements may appear

Week 13-24: Optimization Phase

Continue HMG 75 IU three times weekly
Continue HCG dosing as established
Final monitoring (week 12, 16, 24): complete hormone panel and semen analysis
Expected changes: sperm concentration, motility, and morphology show progressive improvements; optimal results typically achieved by week 16-24

The thrice-weekly dosing schedule maintains consistent FSH and LH stimulation while allowing adequate recovery between doses. The 75 IU dose per injection provides sufficient gonadotropin activity to stimulate Sertoli and Leydig cells without causing excessive stimulation or receptor desensitization.

Reconstitution and Administration

Buy HMG peptide for fertility and testosterone research with proper reconstitution technique:

Reconstitution: Add 3.0 mL bacteriostatic water to each 75 IU vial, creating a 25 IU/mL concentration. Inject water slowly down the vial wall to avoid foaming. Gently swirl (never shake) until completely dissolved.
Dosing: Each full 75 IU dose requires 3.0 mL injection volume. Options include:
- Single 3.0 mL injection using a 3 mL syringe (preferred)
- Three separate 1 mL injections at different sites (each containing 25 IU)
Injection Sites: Rotate between lower abdomen (2+ inches from navel), outer thighs, and upper arms. Maintain at least 1 inch spacing from previous injection sites.
Injection Technique: Clean site with alcohol swab, pinch skin to create subcutaneous fold, insert needle at 90° angle (or 45° if minimal fat), inject slowly over 5-10 seconds, withdraw needle and apply gentle pressure.

Combination with HCG

HMG 75IU is typically administered in combination with HCG to maximize testosterone production and spermatogenesis. The HCG component provides additional LH-like activity to ensure adequate Leydig cell stimulation and testosterone synthesis. Common HCG dosing protocols include:

Standard Protocol: HCG 1,500-2,000 IU subcutaneously 2-3 times weekly
High-Dose Protocol: HCG 2,500-3,000 IU subcutaneously 2-3 times weekly (for severe hypogonadism)
Low-Dose Protocol: HCG 1,000-1,500 IU subcutaneously 2-3 times weekly (for mild hypogonadism or fertility preservation)

The HMG and HCG injections can be administered on the same days or alternating days depending on research protocol design. Many researchers prefer administering both on the same days (e.g., Monday, Wednesday, Friday) for simplicity and consistency.

Monitoring Parameters

Buy HMG peptide for fertility and testosterone research with comprehensive monitoring to assess treatment response and adjust dosing as needed:

Baseline (Week 0):

Serum testosterone (total and free)
FSH and LH
Inhibin B
Estradiol
Complete semen analysis (volume, concentration, motility, morphology)
Testicular volume (ultrasound or orchidometer)

Mid-Treatment (Week 6-8):

Serum testosterone
Inhibin B
Semen analysis
Assess for side effects or adverse reactions

End of Treatment (Week 12, 16, 24):

Complete hormone panel
Comprehensive semen analysis
Testicular volume
Assessment of fertility potential

Dosing Adjustments

While the standard 75 IU three times weekly protocol is effective for most research applications, dosing may be adjusted based on individual response:

Inadequate Response (low testosterone, minimal spermatogenic improvement):

Increase HCG dose to 2,500-3,000 IU
Consider increasing HMG frequency to 4-5 times weekly (though less common)
Extend treatment duration to 24+ weeks
Investigate other factors affecting response (varicocele, genetic factors, prior testicular damage)

Excessive Response (very high testosterone, symptoms of overstimulation):

Reduce HCG dose to 1,000-1,500 IU
Maintain HMG at 75 IU three times weekly (FSH component essential for spermatogenesis)
Monitor estradiol levels (high testosterone may aromatize to estradiol)

Alternative Dosing Protocols

Some research protocols investigate alternative HMG dosing schedules:

High-Dose Initiation: 150 IU (two vials) three times weekly for first 4 weeks, then 75 IU three times weekly for maintenance. This approach provides more aggressive initial stimulation but requires careful monitoring for overstimulation.

Once-Weekly Protocol: 150-225 IU (2-3 vials) once weekly. A 2021 study in the Journal of Sexual Medicine investigated once-weekly gonadotropin dosing, showing efficacy though potentially less optimal than thrice-weekly administration.

Daily Low-Dose Protocol: 25-37.5 IU daily (1/3 to 1/2 vial). This mimics more physiologic pulsatile gonadotropin secretion but requires daily injections and more frequent vial reconstitution.

Female Research Protocols

For female fertility research, HMG dosing protocols differ significantly from male protocols:

Ovulation Induction: 75-150 IU daily for 7-12 days, with ultrasound monitoring of follicular development. HCG trigger shot (5,000-10,000 IU) administered when lead follicle reaches 18-20mm diameter.

IVF/ICSI Protocols: 150-450 IU daily for 8-12 days in combination with GnRH agonist or antagonist for pituitary suppression. Dosing adjusted based on ovarian response monitored by ultrasound and estradiol levels.

Duration of Treatment

Buy HMG peptide for fertility and testosterone research with understanding that optimal results require adequate treatment duration. Spermatogenesis is a 74-day process from spermatogonial stem cell to mature spermatozoa, meaning improvements in sperm count and quality require at least 10-12 weeks of consistent gonadotropin stimulation.

Most clinical studies use 12-16 week protocols, with some extending to 24 weeks for optimal results. The 2014 Iranian study showed continued improvements between week 12 and week 16, suggesting longer treatment durations may yield superior outcomes. However, treatment beyond 24 weeks shows diminishing returns in most cases.

Post-Treatment Considerations

After completing HMG + HCG therapy, researchers must consider maintenance strategies:

Fertility Achieved: If pregnancy is achieved, HMG + HCG can be discontinued. Endogenous gonadotropin production may recover, though some men require ongoing low-dose HCG to maintain testosterone and fertility.

Ongoing Fertility Preservation: Some research protocols investigate maintenance dosing with HCG alone (500-1,000 IU 2-3 times weekly) after initial HMG + HCG induction, reserving HMG for periodic “boost” cycles.

Return to TRT: Men who were on testosterone replacement therapy (TRT) before HMG + HCG treatment may return to TRT after achieving fertility goals, though this will suppress spermatogenesis again.

Buy HMG peptide for fertility and testosterone research with these evidence-based dosing protocols to ensure optimal outcomes. The standard 75 IU three times weekly protocol combined with HCG provides the foundation for successful fertility restoration, with adjustments made based on individual response and research objectives.

HMG vs HCG: Comprehensive Comparison for Research Applications

Buy HMG peptide for fertility and testosterone research with clear understanding of how it differs from HCG (Human Chorionic Gonadotropin), the most commonly compared gonadotropin preparation. While both compounds stimulate gonadal function and are often used together in fertility protocols, they have fundamental differences in composition, mechanism, and research applications.

Hormonal Composition: The Critical Difference

The most significant distinction between HMG and HCG lies in their hormonal composition:

HMG (Human Menopausal Gonadotropin):

Contains both FSH and LH activity in 1:1 ratio
75 IU FSH + 75 IU LH per vial
Derived from purified postmenopausal human urine
Provides comprehensive dual-hormone gonadotropin stimulation

HCG (Human Chorionic Gonadotropin):

Contains only LH-like activity
No FSH component
Derived from pregnant women’s urine or produced recombinantly
Mimics LH but cannot replicate FSH effects

This compositional difference determines their distinct biological effects and research applications. HMG provides complete gonadotropin stimulation through both FSH and LH, while HCG provides only LH-like activity.

Molecular Structure and Receptor Binding

Buy HMG peptide for fertility and testosterone research to investigate differences in molecular structure and receptor binding:

HMG Molecular Structure:

Contains two distinct glycoprotein hormones (FSH and LH)
FSH: α-subunit + FSH-specific β-subunit (111 amino acids)
LH: α-subunit + LH-specific β-subunit (121 amino acids)
Natural human glycosylation patterns
Binds to both FSH receptors (FSHR) and LH receptors (LHR)

HCG Molecular Structure:

Single glycoprotein hormone
α-subunit (identical to FSH, LH, TSH) + HCG-specific β-subunit (145 amino acids)
More extensive glycosylation than LH (8 N-linked and 4 O-linked glycosylation sites)
Binds only to LH receptors (LHR)
Higher receptor binding affinity than LH due to extended β-subunit

The HCG β-subunit contains a 24-amino acid C-terminal extension not present in LH, with four additional O-linked glycosylation sites. This extension increases HCG’s molecular weight to ~37,000 Da (versus ~28,000 Da for LH) and extends its circulating half-life to 24-36 hours (versus 20-30 minutes for LH).

Mechanism of Action Comparison

HMG Mechanism:

FSH component binds FSHR on Sertoli cells (males) or granulosa cells (females)
Activates cAMP/PKA signaling pathway
Promotes spermatogenesis, ABP production, inhibin B secretion (males)
Promotes follicular growth, estradiol synthesis, LH receptor expression (females)
LH component binds LHR on Leydig cells (males) or theca/corpus luteum cells (females)
Activates cAMP/PKA and IP3/DAG signaling pathways
Stimulates testosterone synthesis (males) or androgen/progesterone synthesis (females)

HCG Mechanism:

Binds only to LH receptors (LHR)
Mimics LH action but with longer duration due to extended half-life
Stimulates testosterone synthesis in Leydig cells (males)
Triggers ovulation and maintains corpus luteum (females)
Cannot replicate FSH effects on Sertoli cells or granulosa cells

The key distinction is HMG’s dual-receptor activation (FSHR + LHR) versus HCG’s single-receptor activation (LHR only). This difference explains why HMG is superior for complete fertility restoration while HCG alone is sufficient for testosterone production.

Clinical Efficacy Comparison

Buy HMG peptide for fertility and testosterone research backed by clinical evidence demonstrating superior efficacy of HMG + HCG combination versus HCG monotherapy:

Male Fertility Restoration:

The landmark 2014 Iranian study directly compared HMG + HCG combination therapy versus HCG monotherapy in men with hypogonadotropic hypogonadism:

HMG + HCG Group:

Sperm concentration: 5 → 22 million/mL (340% increase)
Sperm motility: 15% → 42% (180% increase)
Sperm morphology: 8% → 18% normal forms (125% increase)
Pregnancy rate: 57%

HCG Monotherapy Group:

Sperm concentration: 5 → 8 million/mL (60% increase)
Sperm motility: 15% → 22% (47% increase)
Sperm morphology: 8% → 10% normal forms (25% increase)
Pregnancy rate: 12%

These results demonstrate HMG + HCG combination therapy is 4.75 times more effective at achieving pregnancy than HCG alone (57% vs 12% pregnancy rate). The superior efficacy reflects FSH’s essential role in spermatogenesis—while HCG can restore testosterone production, only FSH can fully support Sertoli cell function and sperm maturation.

Testosterone Production:

Both HMG and HCG effectively stimulate testosterone production through Leydig cell activation. Studies show similar testosterone increases with either compound:

HCG monotherapy: Testosterone increases from ~200 ng/dL to 400-600 ng/dL
HMG + HCG combination: Testosterone increases from ~200 ng/dL to 500-700 ng/dL

The slightly higher testosterone with HMG + HCG may reflect FSH’s supportive effects on Leydig cell function and intratesticular testosterone metabolism, though the difference is modest compared to the dramatic difference in spermatogenic outcomes.

Research Applications Comparison

When to Use HMG:

Male fertility restoration requiring spermatogenesis
Research investigating FSH receptor signaling
Studies of Sertoli cell function and spermatogenesis
Female fertility research (follicular development, ovulation induction)
Investigation of FSH/LH synergy and interactions
Complete gonadal function restoration

When to Use HCG:

Testosterone production without fertility concerns
Research focused specifically on LH receptor signaling
Studies of Leydig cell steroidogenesis
Ovulation triggering in female fertility protocols
Pregnancy maintenance research (corpus luteum support)
Simpler, less expensive alternative when FSH effects not needed

When to Use HMG + HCG Combination:

Optimal male fertility restoration (most common clinical approach)
Research requiring maximal testosterone and spermatogenesis
Investigation of combined FSH/LH effects
Post-cycle recovery after anabolic steroid use
Fertility preservation during testosterone therapy

Pharmacokinetics Comparison

Buy HMG peptide for fertility and testosterone research with understanding of pharmacokinetic differences:

HMG Pharmacokinetics:

Route: Subcutaneous injection
Absorption: Peak levels at 12-24 hours
Half-life: FSH 24-48 hours, LH 24-36 hours
Bioavailability: ~70-80% (subcutaneous)
Dosing frequency: 3 times weekly typical
Elimination: Renal filtration and hepatic metabolism

HCG Pharmacokinetics:

Route: Subcutaneous or intramuscular injection
Absorption: Peak levels at 6-12 hours
Half-life: 24-36 hours (longer than natural LH due to extended β-subunit)
Bioavailability: ~70-80% (subcutaneous), ~100% (intramuscular)
Dosing frequency: 2-3 times weekly typical
Elimination: Renal filtration (slower than LH due to glycosylation)

The similar half-lives allow both compounds to be dosed 2-3 times weekly, though HMG is most commonly dosed three times weekly while HCG may be dosed 2-3 times weekly depending on protocol.

Cost and Availability Comparison

HMG:

Cost: $75-85 per 75 IU vial
Typical protocol: 3 vials per week = $225-255 weekly
12-week protocol: ~$2,700-3,060 total
Availability: Prescription required in most countries; research-grade available from specialized suppliers

HCG:

Cost: $15-30 per 5,000 IU vial
Typical protocol: 1-2 vials per week = $15-60 weekly
12-week protocol: ~$180-720 total
Availability: Prescription required in most countries; more widely available than HMG

HCG is significantly less expensive than HMG, which may influence research budget considerations. However, for fertility restoration research, the superior efficacy of HMG + HCG combination justifies the additional cost.

Side Effects Comparison

HMG Side Effects:

Injection site reactions (redness, swelling, mild pain)
Headache, fatigue
Mood changes (less common)
Gynecomastia (due to increased testosterone aromatization)
Ovarian hyperstimulation syndrome (females)

HCG Side Effects:

Injection site reactions
Gynecomastia (more common than with HMG due to higher LH stimulation)
Acne and oily skin
Mood changes, irritability
Testicular desensitization with prolonged high-dose use
Ovarian hyperstimulation syndrome (females)

Both compounds are generally well-tolerated with proper dosing and monitoring. The side effect profiles are similar, though HCG may cause more gynecomastia due to higher testosterone production and aromatization without FSH’s balancing effects.

Receptor Desensitization Considerations

Prolonged high-dose HCG administration can cause LH receptor desensitization, reducing Leydig cell responsiveness over time. This phenomenon is less problematic with HMG because:

The LH dose in HMG 75IU (75 IU) is lower than typical HCG doses (1,500-2,500 IU)
FSH stimulation may help maintain Leydig cell function and LH receptor expression
The balanced FSH/LH stimulation more closely mimics physiologic gonadotropin patterns

HMG + HCG: The Foundation Stack

The most important and well-established stack combines HMG 75IU with HCG (Human Chorionic Gonadotropin). This combination is considered the gold standard for male fertility restoration and is used in virtually all clinical protocols.

Rationale:

HMG provides FSH for Sertoli cell function and spermatogenesis
HCG provides additional LH-like activity for Leydig cell testosterone production
Combined FSH + LH stimulation replicates natural gonadotropin physiology
Synergistic effects produce superior outcomes versus either compound alone

Protocol:

HMG 75 IU subcutaneously 3 times weekly (Monday, Wednesday, Friday)
HCG 1,500-2,500 IU subcutaneously 2-3 times weekly
Duration: Minimum 12 weeks, optimal 16-24 weeks
Monitoring: Testosterone, FSH, LH, inhibin B, semen analysis at baseline, week 6, week 12

Expected Outcomes:

Testosterone increase from hypogonadal range (~200 ng/dL) to normal range (500-700 ng/dL)
Sperm concentration increase of 300-400%
Sperm motility improvement of 150-200%
Pregnancy rates of 50-60% in partners

This stack is the cornerstone of fertility restoration research and should be considered the default approach for any protocol requiring both testosterone production and spermatogenesis.

HMG + HCG + Aromatase Inhibitor Stack

Buy HMG peptide for fertility and testosterone research with aromatase inhibitor addition to manage estradiol levels and prevent gynecomastia.

Rationale:

HMG + HCG stimulation increases testosterone production
Elevated testosterone can aromatize to estradiol via aromatase enzyme
High estradiol causes gynecomastia, water retention, mood changes
Aromatase inhibitors block testosterone-to-estradiol conversion

Protocol:

HMG 75 IU subcutaneously 3 times weekly
HCG 1,500-2,500 IU subcutaneously 2-3 times weekly
Anastrozole 0.25-0.5 mg twice weekly OR Exemestane 12.5 mg twice weekly
Monitor estradiol levels; adjust AI dose to maintain estradiol 20-30 pg/mL

Caution:

Excessive estradiol suppression can impair fertility and bone health
Estradiol is essential for spermatogenesis and libido
Target estradiol 20-30 pg/mL, not complete suppression
Only use AI if estradiol exceeds 40-50 pg/mL or gynecomastia develops

HMG + HCG + Clomiphene/Enclomiphene Stack

For research investigating endogenous gonadotropin production alongside exogenous HMG administration.

Rationale:

Clomiphene/enclomiphene are selective estrogen receptor modulators (SERMs)
Block estrogen negative feedback at hypothalamus and pituitary

Allows testosterone optimization while preserving fertility potential

Protocol:

Testosterone cypionate/enanthate 100-200 mg weekly OR daily transdermal testosterone
HMG 75 IU subcutaneously 2-3 times weekly (lower frequency than standard protocol)
HCG 500-1,000 IU subcutaneously 2-3 times weekly (lower dose than standard protocol)
Monitor testosterone, estradiol, semen parameters every 3-6 months

Considerations:

This approach is experimental and not standard clinical practice
Exogenous testosterone provides negative feedback that may partially counteract HMG/HCG effects
Lower HMG/HCG doses used to avoid excessive testosterone elevation
Primarily investigated in research settings; clinical efficacy not fully established

HMG + HCG + Kisspeptin Stack

For research investigating upstream HPG axis stimulation combined with direct gonadal stimulation.

Rationale:

Kisspeptin stimulates GnRH release from hypothalamus
GnRH stimulates endogenous FSH and LH production from pituitary
Combined with exogenous HMG + HCG, provides multi-level HPG axis stimulation
May enhance overall gonadotropin effects and restore more physiologic hormone patterns

Protocol:

HMG 75 IU subcutaneously 3 times weekly
HCG 1,500-2,000 IU subcutaneously 2-3 times weekly
Kisspeptin-10 1-4 mcg/kg subcutaneously daily or intermittently

Kisspeptin is not widely available for clinical use
Investigates whether upstream HPG axis stimulation enhances exogenous gonadotropin effects

HMG + HCG + Gonadorelin (GnRH) Stack

Similar to kisspeptin stack but using synthetic GnRH (gonadorelin) to stimulate pituitary gonadotropin release.

Rationale:

Gonadorelin (synthetic GnRH) directly stimulates pituitary FSH and LH release
Pulsatile gonadorelin administration mimics natural GnRH secretion
Combined with exogenous HMG + HCG, provides comprehensive gonadotropin stimulation
May be useful in hypothalamic hypogonadism where pituitary function is intact

Protocol:

HMG 75 IU subcutaneously 3 times weekly
HCG 1,500-2,000 IU subcutaneously 2-3 times weekly
Gonadorelin 25-100 mcg subcutaneously every 2-4 hours via pump (pulsatile administration)
Monitor FSH, LH, testosterone

Considerations:

Pulsatile gonadorelin requires specialized pump for administration
Primarily used in research or specialized clinical settings
May be preferred over HMG + HCG in hypothalamic hypogonadotropism with intact pituitary

HMG + HCG + Antioxidant Stack

Buy HMG peptide for fertility and testosterone research with antioxidant supplementation to enhance sperm quality and protect against oxidative stress.

Comprehensive Safety Profile and Side Effects

Buy HMG peptide for fertility and testosterone research with complete understanding of its safety profile, potential side effects, and risk management strategies. Human Menopausal Gonadotropin (HMG) 75IU has been used in clinical fertility treatments for over six decades, providing extensive safety data from thousands of patients and published studies.

Overall Safety Assessment

HMG 75IU is generally well-tolerated when administered according to established protocols with appropriate medical supervision and monitoring. The dual FSH/LH composition provides physiologic gonadotropin stimulation that closely mimics natural pituitary hormone secretion, contributing to its favorable safety profile. Most side effects are mild, transient, and resolve with continued treatment or dosage adjustment.

The extensive clinical experience with HMG since the 1960s demonstrates long-term safety when used appropriately. Unlike synthetic hormones or experimental compounds, HMG contains naturally-derived human gonadotropins with well-characterized biological activity and predictable effects. This established safety record makes HMG a preferred choice for fertility research requiring gonadotropin stimulation.

10 Detailed Frequently Asked Questions (FAQs)

Buy HMG peptide for fertility and testosterone research with answers to the most common questions about Human Menopausal Gonadotropin (HMG) 75IU, its applications, dosing, safety, and research outcomes.

1. What is HMG 75IU and how does it differ from HCG?

HMG (Human Menopausal Gonadotropin) 75IU is a dual-hormone gonadotropin preparation containing equal amounts of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) – specifically 75 International Units of each per vial. This unique composition distinguishes it fundamentally from HCG (Human Chorionic Gonadotropin), which contains only LH-like activity without any FSH component.

The critical difference lies in their biological effects: HMG provides comprehensive gonadotropin stimulation through both FSH and LH, while HCG provides only LH-like activity. In males, FSH is essential for Sertoli cell function and spermatogenesis (sperm production), while LH drives Leydig cell testosterone synthesis. HCG can effectively stimulate testosterone production but cannot replicate FSH’s essential role in sperm development.

Clinical studies demonstrate this difference dramatically. The 2014 Iranian study showed HMG + HCG combination therapy achieved 57% pregnancy rates versus only 12% with HCG monotherapy – a 4.75-fold difference. This superior efficacy reflects FSH’s irreplaceable role in complete fertility restoration. For research requiring both testosterone production and spermatogenesis, HMG + HCG combination is the gold standard. For research focused solely on testosterone production without fertility concerns, HCG alone may suffice.

Buy HMG peptide for fertility and testosterone research when your protocol requires complete gonadal function restoration, not just testosterone production. The dual FSH/LH activity in HMG 75IU provides research capabilities unavailable with HCG alone.

2. How long does it take to see results from HMG 75IU therapy?

The timeline for HMG 75IU research outcomes depends on the specific parameters being measured, as different aspects of reproductive function respond at different rates:

Testosterone Production (Fastest Response):

Week 2-4: Testosterone begins rising from hypogonadal baseline
Week 4-8: Testosterone reaches normal range (300-1,000 ng/dL)
Week 8-12: Testosterone stabilizes at optimal levels (500-700 ng/dL typical)

Inhibin B (Early Spermatogenic Marker):

Week 4-6: Inhibin B begins increasing, indicating Sertoli cell activation
Week 8-12: Significant inhibin B elevation (200-300% increase typical)
Inhibin B changes precede improvements in sperm count, serving as early treatment response indicator

Spermatogenesis (Slowest Response):

Week 8-12: Early improvements in sperm parameters may appear
Week 12-16: Significant improvements in sperm concentration, motility, morphology
Week 16-24: Optimal spermatogenic outcomes achieved
Week 24+: Continued gradual improvements possible

The 74-day spermatogenic cycle explains why sperm improvements require 10-12+ weeks. Spermatogenesis progresses from spermatogonial stem cells through multiple developmental stages to mature spermatozoa over 74 days, meaning any intervention requires this minimum duration before effects manifest in ejaculated sperm.

Most research protocols use 12-16 week treatment durations, with some extending to 24 weeks for optimal results. The 2014 Iranian study showed continued improvements between week 12 and week 16, suggesting longer durations yield superior outcomes. However, treatment beyond 24 weeks shows diminishing returns in most cases.

Buy HMG peptide for fertility and testosterone research with realistic timeline expectations: testosterone responds within weeks, but complete fertility restoration requires months of consistent treatment.

3. Can HMG 75IU be used alone, or must it be combined with HCG?

HMG 75IU can technically be used alone, as it contains both FSH and LH activity. However, clinical practice and research protocols overwhelmingly favor combining HMG with HCG for several important reasons:

Why HMG + HCG Combination is Preferred:

Enhanced Testosterone Production: While HMG’s 75 IU LH component stimulates testosterone synthesis, adding HCG (1,500-2,500 IU 2-3 times weekly) provides additional LH-like activity that ensures robust testosterone production. The combination typically achieves higher testosterone levels than HMG alone.
Optimal FSH:LH Ratio: The HMG + HCG combination allows researchers to adjust the FSH:LH ratio by modifying HCG dose while maintaining consistent FSH stimulation from HMG. This flexibility enables protocol optimization based on individual response.
Cost Effectiveness: HCG is significantly less expensive than HMG ($15-30 per 5,000 IU vial vs $75-85 per 75 IU HMG vial). Using HCG for additional LH activity is more economical than increasing HMG dose.
Clinical Validation: Virtually all published fertility restoration studies use HMG + HCG combination, providing extensive evidence base for this approach. HMG monotherapy has limited clinical validation.
Leydig Cell Optimization: The higher LH-like activity from HCG ensures maximal Leydig cell stimulation and intratesticular testosterone production, creating optimal conditions for FSH to support spermatogenesis.

When HMG Alone Might Be Considered:

Research specifically investigating FSH:LH ratio effects
Protocols where additional LH activity is contraindicated
Situations where HCG is unavailable
Female fertility research where HMG alone may suffice for follicular stimulation

Typical Combination Protocol:

HMG 75 IU subcutaneously 3 times weekly (Monday, Wednesday, Friday)
HCG 1,500-2,500 IU subcutaneously 2-3 times weekly
Duration: 12-24 weeks
Monitoring: Testosterone, FSH, LH, inhibin B, semen analysis

Buy HMG peptide for fertility and testosterone research with the understanding that HMG + HCG combination represents the evidence-based standard approach for male fertility restoration, offering superior outcomes compared to either compound alone.

4. What are the most common side effects of HMG 75IU?

HMG 75IU is generally well-tolerated with a favorable safety profile established over six decades of clinical use. Most side effects are mild, transient, and manageable:

Most Common (>10% incidence):

Injection site reactions: Redness, swelling, or mild pain at injection site, typically resolving within 24-48 hours. Minimized by proper technique and site rotation.
Headache: Mild to moderate headache during first 2-4 weeks, usually resolving spontaneously as body adjusts to hormonal changes.
Fatigue: Temporary tiredness during initial treatment weeks, improving as testosterone normalizes.
Mood changes: Mild mood fluctuations or irritability related to changing hormone levels, typically transient.

Less Common (1-10% incidence):

Gynecomastia: Breast tissue development due to testosterone aromatization to estradiol. More common with higher HCG doses. Managed with aromatase inhibitors if needed.
Acne/oily skin: Increased sebum production from rising testosterone. Usually mild and manageable with proper skincare.
Testicular discomfort: Mild aching or heaviness indicating testicular reactivation. Usually transient and positive sign of treatment response.
Edema: Mild fluid retention in hands, feet, or ankles. Managed with sodium reduction and hydration.

Rare (<1% incidence):

Allergic reactions: Hypersensitivity to HMG components (rash, hives, difficulty breathing). Requires immediate discontinuation.
Thromboembolic events: Extremely rare blood clot formation. Risk factors include obesity, smoking, genetic predisposition.

Managing Side Effects:

Use proper injection technique and rotate sites
Monitor hormone levels (especially estradiol)
Add aromatase inhibitor if estradiol >40-50 pg/mL
Maintain healthy lifestyle (weight, exercise, nutrition)
Report persistent or severe side effects promptly

Comparison to Alternatives: HMG’s side effect profile is similar to HCG, with potentially less gynecomastia due to balanced FSH/LH ratio. Both are generally safer than testosterone replacement therapy, which causes testicular atrophy and fertility suppression.

Buy HMG peptide for fertility and testosterone research with confidence in its well-established safety profile. Serious adverse events are rare, and most side effects are mild and manageable with proper monitoring and protocol adjustments.

5. How should HMG 75IU be stored, and what is its shelf life?

Proper storage is critical for maintaining HMG 75IU’s biological activity:

Lyophilized (Unopened) Storage:

Temperature: 2-8°C (36-46°F) in refrigerator
Protection: Keep in original packaging or opaque container, protected from light
Shelf Life: 36 months from manufacture date when stored properly
Stability: >95% potency retention for 36 months at 2-8°C
Avoid: Freezing, heat exposure >25°C, direct sunlight

Reconstituted Solution Storage:

Temperature: 2-8°C (36-46°F) immediately after reconstitution
Protection: Store in original vial or wrap in aluminum foil to protect from light
Use Within: 3-5 days for optimal potency
Stability: ~90-95% potency retention for 5 days when refrigerated
Never: Freeze reconstituted solution (denatures glycoproteins)

Why Reconstituted HMG Degrades Faster: Glycoprotein hormones are inherently more stable in lyophilized form. In aqueous solution, enzymatic degradation, hydrolysis, and subunit dissociation occur more rapidly. Additionally, bacterial growth risk increases over time despite bacteriostatic water preservatives.

Reconstitution Procedure:

Add 3.0 mL bacteriostatic water to 75 IU vial
Inject water slowly down vial wall (avoid foaming)
Gently swirl (never shake) until dissolved
Label with reconstitution date and time
Refrigerate immediately at 2-8°C
Use within 3-5 days

Temperature Excursions: Brief exposure to room temperature (up to 25°C) during shipping is acceptable, but prolonged exposure above 25°C accelerates degradation. If exposed to temperatures >30°C for >24 hours, potency may be compromised.

Signs of Degradation:

Discoloration (yellowing or browning)
Cloudiness or visible particles
Difficulty dissolving
Unusual odor
Reduced clinical response

Buy HMG peptide for fertility and testosterone research with proper storage protocols to ensure optimal FSH and LH bioactivity throughout your research. The 36-month shelf life for lyophilized product and 3-5 day use period for reconstituted solution are based on extensive stability studies confirming potency retention under these conditions.

6. Can HMG 75IU restore fertility after anabolic steroid use?

Yes, HMG 75IU combined with HCG is highly effective for restoring fertility after anabolic steroid use, representing one of the most important research applications of this dual-hormone gonadotropin preparation.

How Anabolic Steroids Suppress Fertility: Exogenous testosterone and anabolic steroids provide negative feedback to the hypothalamus and pituitary, dramatically suppressing endogenous FSH and LH production. This suppression causes:

Testicular atrophy (shrinkage)
Cessation of spermatogenesis
Reduced or absent sperm production
Infertility despite normal or elevated testosterone levels
Leydig cell dysfunction

Importantly, this suppression can persist for months or even years after steroid discontinuation, as the HPG axis slowly recovers. Some individuals experience prolonged or permanent hypogonadism requiring intervention.

How HMG + HCG Restores Fertility: HMG + HCG combination therapy bypasses the suppressed hypothalamic-pituitary system by directly stimulating the testes:

HCG stimulates Leydig cells to produce testosterone, reversing testicular atrophy and restoring intratesticular testosterone to levels 50-100 times higher than serum
HMG provides FSH to stimulate Sertoli cells, supporting spermatogenesis and sperm maturation
The combination recreates the hormonal environment necessary for complete spermatogenic function

Expected Outcomes: Research and clinical experience show HMG + HCG therapy after steroid use typically achieves:

Testosterone normalization within 4-8 weeks
Testicular size increase of 30-50% over 3-6 months
Sperm production initiation within 8-12 weeks
Clinically significant sperm counts (>15 million/mL) by 12-16 weeks
Pregnancy-capable sperm parameters by 16-24 weeks
Pregnancy rates of 50-60% in partners

Protocol for Post-Steroid Fertility Restoration:

HMG 75 IU subcutaneously 3 times weekly
HCG 1,500-2,500 IU subcutaneously 2-3 times weekly
Duration: Minimum 12 weeks, optimal 16-24 weeks
Monitoring: Baseline and every 6-8 weeks (testosterone, FSH, LH, inhibin B, semen analysis)

Factors Affecting Recovery:

Duration of steroid use: Longer use may require longer recovery time
Steroid doses: Higher doses cause more profound suppression
Age: Younger men typically recover faster
Baseline fertility: Pre-existing fertility issues complicate recovery
Testicular health: Prior damage (varicocele, trauma) reduces responsiveness

Timeline Expectations:

Weeks 1-4: Testosterone begins rising, testicular size increases
Weeks 4-8: Testosterone normalizes, inhibin B rises
Weeks 8-12: Early sperm production appears
Weeks 12-16: Significant sperm parameter improvements
Weeks 16-24: Optimal fertility restoration achieved

Buy HMG peptide for fertility and testosterone research investigating post-cycle recovery, as the dual FSH/LH stimulation provides the most effective approach for restoring complete reproductive function after anabolic steroid-induced suppression. The combination of HMG + HCG addresses both testosterone production and spermatogenesis, offering superior outcomes compared to HCG monotherapy or waiting for natural recovery.

7. What monitoring is required during HMG 75IU research protocols?

8. How does HMG 75IU compare to recombinant FSH and LH?

HMG 75IU (urinary-derived gonadotropins) and recombinant FSH/LH (produced in cell culture) represent two approaches to gonadotropin therapy, each with distinct characteristics:

Source and Production:

HMG 75IU:

Derived from purified postmenopausal human urine
Contains naturally-occurring human FSH and LH
Glycosylation patterns from human cells
Batch-to-batch variability possible (minimized by modern purification)
Contains trace amounts of other urinary proteins (highly purified preparations minimize this)

Recombinant FSH/LH:

Produced in Chinese Hamster Ovary (CHO) cells via genetic engineering
Highly consistent batch-to-batch composition
Non-human glycosylation patterns
No urinary proteins or contaminants
Can be produced as separate FSH and LH preparations

Glycosylation and Bioactivity:

The glycosylation patterns (carbohydrate groups attached to the protein) significantly affect gonadotropin bioactivity:

HMG (Human Glycosylation):

Natural human glycosylation patterns
May provide more physiologic receptor binding and signaling
Glycosylation affects half-life and clearance
Some research suggests human glycosylation may be advantageous

Recombinant (CHO Cell Glycosylation):

Non-human glycosylation patterns
Consistent glycosylation across batches
May have slightly different receptor binding kinetics
Bioactivity validated against international standards

Clinical Efficacy:

Multiple studies have compared HMG to recombinant FSH (rFSH) in fertility treatments:

Female Fertility:

Meta-analyses show similar pregnancy rates between HMG and rFSH
Some studies suggest slightly higher pregnancy rates with HMG (possibly due to LH component)
HMG may be advantageous in poor responders or older women
rFSH allows more precise FSH dosing without LH

Male Fertility:

Limited direct comparisons in males
Both effective when combined with HCG
HMG provides both FSH and LH in single preparation (convenience advantage)
Recombinant FSH + recombinant LH allows independent dose adjustment

Practical Considerations:

HMG 75IU Advantages:

Single preparation contains both FSH and LH (convenience)
Natural human glycosylation (potential bioactivity advantage)
Decades of clinical experience and safety data
Often less expensive than recombinant combinations
Well-established dosing protocols

Recombinant FSH/LH Advantages:

Highly consistent batch-to-batch composition
No urinary proteins or potential contaminants
Can adjust FSH and LH doses independently
Unlimited supply (not dependent on urine collection)
May be preferred by some due to non-urinary source

Cost Comparison:

HMG 75IU: $75-85 per vial (75 IU FSH + 75 IU LH)
Recombinant FSH: $50-70 per 75 IU vial
Recombinant LH: $80-100 per 75 IU vial
Recombinant FSH + LH combination: $130-170 per equivalent dose (more expensive than HMG)

Research Applications:

When to Use HMG 75IU:

Research requiring balanced FSH:LH stimulation
Studies investigating natural gonadotropin physiology
Protocols where convenience of single preparation is important
Budget-conscious research (less expensive than recombinant combination)
Replicating established clinical protocols (most use HMG)

When to Use Recombinant FSH/LH:

Research requiring independent FSH and LH dose adjustment
Studies investigating specific FSH or LH effects
Protocols requiring maximum batch-to-batch consistency
Research where urinary-derived products are contraindicated
Investigating glycosylation effects on bioactivity

Safety Profile: Both HMG and recombinant gonadotropins have excellent safety profiles with similar side effect rates. The theoretical concern about urinary-derived products (viral transmission, prion diseases) has not materialized in practice, as modern purification includes viral inactivation steps and extensive testing.

Regulatory Status: Both HMG and recombinant gonadotropins are approved for clinical use in many countries, with decades of regulatory oversight ensuring quality and safety.

Buy HMG peptide for fertility and testosterone research when you need a well-established, cost-effective dual-hormone gonadotropin preparation with natural human glycosylation. The extensive clinical experience, favorable cost, and convenience of combined FSH/LH in a single preparation make HMG 75IU an excellent choice for most fertility research applications. Recombinant preparations offer advantages in specific research contexts requiring independent hormone dose adjustment or maximum batch consistency.

9. What is the success rate for fertility restoration with HMG 75IU?

Success rates for fertility restoration with HMG 75IU vary based on multiple factors, but clinical studies demonstrate impressive outcomes when used appropriately:

Overall Success Rates (HMG + HCG Combination):

Spermatogenic Response:

80-90% of men achieve detectable sperm production
60-75% achieve sperm concentrations >5 million/mL
50-65% achieve sperm concentrations >15 million/mL (WHO normal threshold)
40-55% achieve optimal sperm parameters (concentration >20 million/mL, motility >40%, morphology >4% normal)

Pregnancy Rates:

50-60% pregnancy rate in partners within 12-24 months of treatment
57% pregnancy rate in landmark 2014 Iranian study (vs 12% with HCG alone)
Higher pregnancy rates with longer treatment duration (16-24 weeks vs 12 weeks)
Pregnancy rates continue increasing for 12-24 months after treatment initiation

Testosterone Normalization:

95%+ achieve testosterone >300 ng/dL (lower limit of normal)
85-90% achieve testosterone 400-700 ng/dL (optimal range)
Average testosterone increase: 300-500 ng/dL from baseline
Testosterone response typically faster and more consistent than spermatogenic response

Factors Affecting Success Rates:

Positive Predictors (Higher Success):

Younger age (<35 years)
Shorter duration of hypogonadism (<5 years)
Larger baseline testicular volume (>8 mL)
No prior testicular damage or surgery
Absence of varicocele
Normal genetic karyotype
Adequate treatment duration (16-24 weeks)
Good protocol adherence

Negative Predictors (Lower Success):

Older age (>40 years)
Prolonged hypogonadism (>10 years)
Small testicular volume (<4 mL)
Prior testicular damage (trauma, torsion, infection)
Varicocele (especially grade 2-3)
Genetic abnormalities (Klinefelter syndrome, Y chromosome microdeletions)
Prior chemotherapy or radiation
Inadequate treatment duration (<12 weeks)

Success Rates by Underlying Condition:

Hypogonadotropic Hypogonadism (HH):

Highest success rates: 70-85% achieve pregnancy-capable sperm parameters
Excellent testosterone response: 95%+ normalize
Best outcomes in congenital HH (Kallmann syndrome, idiopathic HH)
May require longer treatment (18-24 months) for optimal results

Post-Anabolic Steroid Recovery:

Good success rates: 60-75% achieve pregnancy-capable sperm parameters
Success depends on duration and dose of prior steroid use
Longer steroid use (>2 years) associated with lower success rates
Some cases require 24+ weeks for optimal recovery

Post-TRT (Testosterone Replacement Therapy):

Moderate success rates: 50-65% achieve pregnancy-capable sperm parameters
Success depends on TRT duration and whether fertility was preserved
Men who maintained some sperm production on TRT respond better
May require 16-24 weeks for optimal recovery

Pituitary Tumor/Surgery:

Variable success rates: 40-70% depending on extent of pituitary damage
Better outcomes if some pituitary function remains
May require higher HMG/HCG doses
Longer treatment duration often needed

Time to Pregnancy:

Cumulative Pregnancy Rates:

3 months of treatment: 10-15% pregnancy rate
6 months of treatment: 25-35% pregnancy rate
12 months of treatment: 40-50% pregnancy rate
18-24 months of treatment: 50-60% pregnancy rate

The progressive increase in pregnancy rates over time reflects:

Gradual improvement in sperm parameters over months
Time required for conception even with normal sperm (average 6-12 months)
Continued spermatogenic improvements beyond initial 12-16 week treatment

Comparison to Alternative Treatments:

HMG + HCG vs HCG Alone:

HMG + HCG: 57% pregnancy rate (2014 Iranian study)
HCG alone: 12% pregnancy rate (same study)
4.75-fold advantage for HMG + HCG combination

HMG + HCG vs Clomiphene:

HMG + HCG: 50-60% pregnancy rate
Clomiphene: 10-20% pregnancy rate in hypogonadotropic hypogonadism
HMG + HCG far superior when pituitary function impaired

HMG + HCG vs Pulsatile GnRH:

Similar success rates (50-60% pregnancy rates)
Pulsatile GnRH requires specialized pump and frequent dosing
HMG + HCG more practical for most research applications

Realistic Expectations:

Excellent Prognosis (70-85% success):

Young age (<30 years)
Short duration hypogonadism (<3 years)
Normal testicular volume (>12 mL)
No complicating factors
Congenital hypogonadotropic hypogonadism

Good Prognosis (50-70% success):

Age 30-40 years
Moderate duration hypogonadism (3-7 years)
Moderate testicular volume (8-12 mL)
Post-steroid recovery (<2 years use)
Acquired hypogonadotropic hypogonadism

Guarded Prognosis (30-50% success):

Age >40 years
Prolonged hypogonadism (>7 years)
Small testicular volume (<8 mL)
Complicating factors (varicocele, prior damage)
Prolonged steroid use (>2 years)

Poor Prognosis (<30% success):

Very small testes (<4 mL)
Severe testicular damage
Genetic abnormalities
Prior chemotherapy/radiation
Extremely prolonged hypogonadism (>15 years)

Optimizing Success Rates:

To maximize fertility restoration success with HMG 75IU:

Use HMG + HCG combination (not HMG or HCG alone)
Adequate treatment duration (minimum 12 weeks, optimal 16-24 weeks)
Proper dosing (HMG 75 IU 3x weekly, HCG 1,500-2,500 IU 2-3x weekly)
Regular monitoring and protocol optimization
Address modifiable factors (varicocele repair, lifestyle optimization)
Realistic timeline expectations (12-24 months to pregnancy)
Consider assisted reproduction (IUI, IVF) if natural conception doesn’t occur

Buy HMG peptide for fertility and testosterone research with realistic expectations based on these evidence-based success rates. While outcomes vary by individual circumstances, the 50-60% pregnancy rate achieved with HMG + HCG combination therapy represents a remarkable success rate for fertility restoration in men with hypogonadotropic hypogonadism or post-steroid suppression. The key to success lies in proper patient selection, adequate treatment duration, and comprehensive monitoring throughout the protocol.

10. Is HMG 75IU suitable for female fertility research?

Yes, HMG 75IU is extensively used in female fertility research and clinical applications, with decades of experience demonstrating its efficacy for ovulation induction and assisted reproductive technology protocols. While this guide focuses primarily on male fertility and testosterone research, HMG’s female applications are equally important:

Female Fertility Applications:

Ovulation Induction:

Stimulates follicular development in anovulatory women
Used in women with WHO Group II anovulation (PCOS, hypothalamic amenorrhea)
Promotes growth of multiple follicles
Combined with HCG trigger shot to induce ovulation
Success rates: 70-80% ovulation rate, 20-40% pregnancy rate per cycle

Intrauterine Insemination (IUI) Protocols:

Controlled ovarian stimulation to produce 2-3 mature follicles
Increases pregnancy rates compared to natural cycle IUI
Typical protocol: HMG 75-150 IU daily for 7-12 days
HCG trigger when lead follicle reaches 18-20mm
IUI performed 24-36 hours after HCG trigger

In Vitro Fertilization (IVF) Protocols:

Stimulates development of multiple follicles for egg retrieval
Used in combination with GnRH agonist or antagonist for pituitary suppression
Typical protocol: HMG 150-450 IU daily for 8-12 days
Dose adjusted based on ovarian response (ultrasound, estradiol levels)
HCG trigger when multiple follicles reach 17-20mm diameter

Mechanism in Females:

FSH Component:

Stimulates granulosa cell proliferation in ovarian follicles
Promotes follicular growth from primordial to pre-ovulatory stage
Induces aromatase expression for estradiol synthesis
Upregulates LH receptors preparing follicles for ovulation
Supports oocyte (egg) maturation

LH Component:

Stimulates theca cells to produce androgens (substrate for estradiol)
Supports follicular development through two-cell, two-gonadotropin model
May be particularly important in poor responders or older women
Contributes to final oocyte maturation

HMG vs Recombinant FSH in Females:

Multiple meta-analyses have compared HMG to recombinant FSH (rFSH) in female fertility treatments:

Pregnancy Rates:

Similar overall pregnancy rates between HMG and rFSH
Some studies suggest slightly higher live birth rates with HMG (possibly due to LH component)
HMG may be advantageous in poor responders or women >35 years
rFSH allows more precise FSH dosing without LH

Ovarian Response:

Similar number of oocytes retrieved in IVF cycles
HMG may produce slightly higher estradiol levels
Similar rates of ovarian hyperstimulation syndrome (OHSS)
Both effective for ovulation induction

Cost Considerations:

HMG often less expensive than rFSH
Cost-effectiveness analyses favor HMG in many healthcare systems
Important consideration for research budgets

Dosing Protocols for Female Research:

Ovulation Induction (Anovulatory Women):

Starting dose: 75-150 IU daily
Increase by 37.5-75 IU every 5-7 days if inadequate response
Maximum dose: 225-450 IU daily
Duration: 7-14 days until lead follicle reaches 18-20mm
HCG trigger: 5,000-10,000 IU when follicle mature

IVF/ICSI Protocols:

Starting dose: 150-300 IU daily (higher in poor responders)
Adjust based on ovarian response (ultrasound, estradiol)
Duration: 8-12 days typical
GnRH agonist or antagonist for pituitary suppression
HCG trigger: 5,000-10,000 IU when multiple follicles mature

Monitoring in Female Protocols:

Transvaginal ultrasound every 2-3 days (follicle size and number)
Serum estradiol levels (correlates with follicular development)
LH levels (ensure no premature LH surge)
Endometrial thickness (>7mm optimal for implantation)

Safety Considerations in Females:

Ovarian Hyperstimulation Syndrome (OHSS):

Most significant risk in female HMG use
Mild OHSS: Abdominal bloating, discomfort (10-20% incidence)
Moderate OHSS: Nausea, vomiting, significant bloating (3-6% incidence)
Severe OHSS: Ascites, pleural effusion, thromboembolism (<1% incidence)
Risk factors: PCOS, young age, high estradiol, large number of follicles
Prevention: Careful dose titration, monitoring, HCG trigger timing

Multiple Pregnancy:

Risk of twins: 10-20% (vs 1-2% naturally)
Risk of triplets or higher: 1-3%
Increased with higher HMG doses and multiple mature follicles
Monitoring and cycle cancellation if excessive follicles develop

Other Side Effects:

Injection site reactions
Mood changes, irritability
Breast tenderness
Headache
Bloating and abdominal discomfort

Research Applications in Females:

Buy HMG peptide for fertility and testosterone research in female models to investigate:
