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

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

What is the regulatory status of Tesamorelin?

Tesamorelin 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 Tesamorelin in your jurisdiction.

Growth Hormone Secretagogues

Tesamorelin

Also known as: Egrifta

Tesamorelin (Egrifta / Egrifta SV) is a stabilized analog of human GHRH(1-44) with a trans-3-hexenoic acid moiety at the N-terminus that protects against protease degradation. FDA-approved in November 2010 for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy, it is the only FDA-approved GHRH analog for this indication. Off-label use for general body composition and visceral fat reduction in non-HIV populations is common but outside the approved label.
