Ipamorelin 5mg
Ipamorelin, the five-residue GHS-R1a agonist, in a 5 mg freeze-dried fill
Ipamorelin is a five-residue growth hormone secretagogue containing two D-amino acids and an amidated C-terminus. This vial holds 5 mg of freeze-dried powder, half the amount in the 10 mg main fill, and is made and tested as its own lot. Published work on ipamorelin covers growth hormone release in cell, rat and pig studies, its selectivity against stress hormones and the ghrelin receptor it acts on.

Other fills
This is the 5 mg fill. The Ipamorelin 10mg page is the main listing for this compound, with the full research summary and every fill side by side. Other fills: 10 mg.
What the research covers
In the 1998 paper that introduced it, ipamorelin released growth hormone through the GHRP receptor with a potency close to GHRP-6, and in swine it kept ACTH and cortisol at the levels seen after GHRH even at more than 200 times its ED50 for growth hormone release1. Those results come from animal and cell work. The Ipamorelin 10 mg page has the full research summary, including the receptor biology and a rat study of muscle and bone.
The Sermorelin vs Ipamorelin vs Tesamorelin guide covers the literature in more depth.
How each lot is tested
Every lot is tested in PrymaLab’s own laboratory in Ashland, Kentucky before release: RP-HPLC for purity, LC-MS for identity, Karl Fischer titration for water, LAL for endotoxin and USP <71> for sterility. The results for the lot now shipping are in the certificate panel on this page, and the certificate number, key and QR code can be checked on the verify page. These are in-house results from PrymaLab Analytical, not an independent test, and the lab is not accredited to ISO 17025. The third-party testing guarantee on this page still applies: if any independent laboratory finds the wrong compound, or less than the stated purity or amount, the order is refunded and the cost of the test is reimbursed.
Frequently asked questions
Is the 5 mg vial the same peptide as the 10 mg vial?
Yes: Aib-His-D-2-Nal-D-Phe-Lys-NH2 with a theoretical mass of 711.9 Da. 5 mg is about 7.0 µmol, a little less after the certificate's water content. The 5 mg fill is its own lot with its own certificate.
Does ipamorelin need any special handling?
Its safety data sheet lists skin, eye and respiratory irritation hazards and asks for storage locked up. Keep the sealed vial at −20 °C, dry and dark, and the reconstituted solution at 2 to 8 °C away from light.
