All certificates in the COA libraryAbout Melanotan 1
Melanotan 1 is a degradation-resistant linear α-MSH analogue and the reference ligand for the melanocortin-1 receptor in binding assays. The Nle⁴ and D-Phe⁷ substitutions give it the stability the native hormone lacks.
Supplied for in-vitro laboratory research. Not for human or veterinary use.

Shipping & questions
How is purity verified?+
Every lot is sent to an independent third-party laboratory before it is listed. Certificates report HPLC-UV purity, LC-MS identity and net content, and some lots carry extended panels such as heavy metals, endotoxin or sterility. The certificate names the laboratory and report number; your lot’s certificate is linked from its product page and filed in the COA library.
What are these compounds sold for?+
Our compounds are supplied exclusively for in-vitro laboratory, analytical and educational research. They are not approved for human or veterinary use, diagnosis or treatment, and by ordering you confirm you are a qualified researcher.
How does “buy more, save more” work?+
Every research vial in your cart counts toward one total, whatever the compounds or strengths. Two or more vials take 5% off every vial, three or more take 10%, and ten or more take 15% — applied automatically, no code. A discount code can go on top; together they take up to 35% off vials. Mists, topicals and supplies aren’t counted. During the Fall Sale (through October 31) 35% comes off every product instead, with no code, and that is the most a code can bring an order to.
When will my order leave?+
Order by 4 PM ET and it leaves our US facility that business day; anything later goes out within 24 hours. Tracking is emailed at dispatch. US shipping is free over $150 and $9.95 otherwise.
How should peptides be stored?+
For long-term storage, freeze lyophilised vials at −20 °C (2–8 °C is fine for short periods) and keep them away from light and moisture. After reconstitution, keep it refrigerated (2–8 °C) and finish it within 30 days.
For research use only. Not for human or veterinary use, not for diagnostic or therapeutic procedures, and not evaluated by the FDA.
