Which vendors sell Ipamorelin with independent COA testing?

44 vendors in the Merit Verified directory have independent COA evidence on file for Ipamorelin — 287 COAs total. COA coverage and test dates are listed on the Ipamorelin page at https://meritverified.org/peptides/ipamorelin.

How do I verify the quality of Ipamorelin from a vendor?

To verify Ipamorelin quality, look for an independent certificate of analysis (COA) from a third-party lab — not a lab the vendor owns or pays directly. The COA should state the tested compound, lot number, purity percentage (identity and concentration), and the lab's name. Cross-reference the lot number against the vendor's current stock. Merit Verified indexes COAs for Ipamorelin at https://meritverified.org/peptides/ipamorelin so you can compare evidence across vendors before buying.

What is the regulatory status of Ipamorelin?

Ipamorelin is tracked in the Merit Verified registry. Regulatory status for research peptides in the US has been evolving — the FDA has reclassified a number of peptides out of the 503A compounding ingredient list since 2025. Merit Verified does not provide legal or regulatory advice; check official FDA sources or consult a licensed professional for the current status of Ipamorelin in your jurisdiction.

Growth Hormone Secretagogues

Ipamorelin

Also known as: IPA

Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) originally developed by Novo Nordisk and later advanced by Helsinn/Nycomed. It is a selective ghrelin receptor agonist / growth hormone secretagogue (GHRP). Its defining feature versus older GHRPs (GHRP-2, GHRP-6, hexarelin) is that in preclinical and early clinical studies it raised GH without meaningfully increasing ACTH, cortisol, or prolactin. It is not FDA-approved for any indication; a Phase 2 trial for postoperative ileus failed to meet its primary endpoint and clinical development was discontinued. In the wellness/grey market it is sold as a research chemical and used off-label for anti-aging and body-composition goals despite no clinically validated human dose for those uses.
