Which vendors sell Sermorelin with independent COA testing?

38 vendors in the Merit Verified directory have independent COA evidence on file for Sermorelin — 161 COAs total. COA coverage and test dates are listed on the Sermorelin page at https://meritverified.org/peptides/sermorelin.

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

To verify Sermorelin 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 Sermorelin at https://meritverified.org/peptides/sermorelin so you can compare evidence across vendors before buying.

What is the regulatory status of Sermorelin?

Sermorelin 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 Sermorelin in your jurisdiction.

Growth Hormone Secretagogues

Sermorelin

Also known as: Geref

Sermorelin is a synthetic analog of growth hormone-releasing hormone (GHRH) consisting of the first 29 amino acids of the 44-aa native hormone — the shortest fragment that retains full biological activity. It was FDA-approved in the 1990s as Geref (EMD Serono) for diagnostic testing of pituitary GH reserve and later for pediatric idiopathic GH deficiency, but was withdrawn from the US market in 2008–2009 at the manufacturer's request for commercial reasons (not safety or efficacy). It remains on the FDA Category 1 list of bulk substances nominated for use in 503A compounding, where it is now widely prescribed off-label for adult GH insufficiency and "anti-aging" indications.
