Which vendors sell Melanotan II with independent COA testing?

22 vendors in the Merit Verified directory have independent COA evidence on file for Melanotan II — 57 COAs total. COA coverage and test dates are listed on the Melanotan II page at https://meritverified.org/peptides/melanotan-ii.

How do I verify the quality of Melanotan II from a vendor?

To verify Melanotan II 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 Melanotan II at https://meritverified.org/peptides/melanotan-ii so you can compare evidence across vendors before buying.

What is the regulatory status of Melanotan II?

Melanotan II 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 Melanotan II in your jurisdiction.

Melanocortin

Melanotan II

Also known as: MT-2

Melanotan II (MT-II) is a cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH) — Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2 — developed at the University of Arizona in the 1980s by Hruby, Hadley, and colleagues as a candidate photoprotection / sunless-tanning agent. It has never been approved by the FDA or any other regulator for any indication; clinical development was abandoned and it is sold only via grey-market research-chemical channels. Genuine safety signals have been reported, including darkening of existing moles, eruptive atypical nevi, and case reports of new primary melanoma in young tanning-seeking users.
