Which vendors sell GHRP-2 with independent COA testing?

6 vendors in the Merit Verified directory have independent COA evidence on file for GHRP-2 — 19 COAs total. COA coverage and test dates are listed on the GHRP-2 page at https://meritverified.org/peptides/ghrp-2.

How do I verify the quality of GHRP-2 from a vendor?

To verify GHRP-2 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 GHRP-2 at https://meritverified.org/peptides/ghrp-2 so you can compare evidence across vendors before buying.

What is the regulatory status of GHRP-2?

GHRP-2 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 GHRP-2 in your jurisdiction.

Growth Hormone Secretagogues

GHRP-2

Also known as: Growth Hormone Releasing Peptide-2

GHRP-2 (pralmorelin) is a synthetic hexapeptide ghrelin receptor agonist that stimulates pituitary growth hormone release. It is approved in Japan (Kaken Pharmaceutical, 2004) as a single-dose diagnostic agent for GH deficiency, but is NOT FDA-approved in the US and is research-only. Unlike ipamorelin, GHRP-2 is non-selective and modestly raises ACTH, cortisol, and prolactin.
