KNOWLEDGE BASE

FAQ

PrymaLab is an American-made peptide research supply company specializing in high-quality reagents. We specialize in providing the purest research peptides, lyophilized peptide compounds, and liquid research reagents and chemicals to scientists, laboratories, and qualified researchers worldwide. Every product in our peptide catalog is manufactured in the USA and guaranteed to meet 99%+ purity standards verified through HPLC testing and third-party analysis.
Absolutely not. Every product sold on PrymaLab.net is strictly for research use only and is not intended for human consumption under any circumstances. If any product is intentionally or accidentally ingested, contact a healthcare provider immediately. Any customer who indicates intent to consume our research peptides will have their order canceled and their account permanently suspended. PrymaLab will not discuss potential effects of ingestion — doing so would be unlawful.
Most orders are processed and shipped the same day they are placed. Orders submitted after 12:00 PM EST will ship the following business day (excluding Sundays). Because all of our research peptides ship from within the United States, delivery times are exceptionally fast regardless of your chosen payment method.
We do not process orders by phone. We utilize a professional answering service that will forward your inquiry to our support team, but all research peptide orders must be placed directly through our website at PrymaLab.net to ensure accuracy and security.
Our reputation depends on delivering the purest research peptides available. Every product is tested using HPLC analysis and mass spectrometry to verify molecular identity and purity. We guarantee 99%+ purity on all research peptides — if any product fails to meet this standard, we replace it free of charge. Certificates of analysis are available with your order for complete transparency.
All of our research peptides and liquid research chemicals are proudly manufactured in the United States. PrymaLab is committed to American-made quality, ensuring every product meets the highest standards of purity, potency, and scientific integrity.

No. All liquid research chemicals are stable at room temperature. However, we recommend refrigerating any research peptides after reconstitution with bacteriostatic water to preserve stability.
Lyophilized is the scientific term for freeze-dried. It describes the state in which our research peptides are shipped and stored. Lyophilized peptides remain stable at room temperature for approximately two years and do not require refrigeration until reconstituted. This method preserves molecular integrity, purity, and potency throughout storage and transit.

ok i was honestly skeptical because ive tried SO many hair supplements and most of them do nothing. But the HHB blend is different, within a few weeks of my research protocol i started noticing less breakage and my nails stopped peeling at the tips. The janoshik COA gives me confidence im working with a legit product. Price is way better then the competition and i love that its american made. Already set up my monthly subscription

What really sets this company apart is the pricing, i compared it to 4 other sites and prymalab is cheaper accross the board. Will be a regular customer

This blend is priced better then buying the two compounds seperately from most other sites, which is wild. Packaging was solid, came with the janoshik report and everything looked great. I've tried 3 other suppliers for this same blend and prymalab is the best combination of price, quality and shipping speed. Veteran owned too which is always a plus in my book

This is my second order of the HHB blend and i have no plans to stop. The quality is consistent, which matters alot for serious research protocols. Both batches had janoshik COA's and both tested clean. I set up the monthly subscription after my first order and the savings are significant. Prymalab is genuinely the best supplier i've used in terms of price AND quality combined, usually you have to sacrafice one for the other

First time ordering capsules instead of powder and honestly its so much more convenient. The 10mg dosing is accurate per the COA, janoshik verified. Price per capsule is cheaper then anywhere else i compared. Shipping was quick, maybe 2-3 business days. Set up a monthly subscription and saving even more. Solid company

Really impressed with the quality here. The nasal spray format is so much more convenient for my research protocols and the concentration is exactly what the label says per the lab report.
