About Melanotan II

Melanotan II is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH). Its lactam bridge confers greater structural stability than native α-MSH, which is why it appears throughout melanocortin-receptor research.

Purvexis supplies melanotan II as a lyophilised powder in sealed vials and as a measured spray, manufactured in the United States and released at ≥99% verified purity.

Melanotan II — Frequently Asked Questions

What is melanotan II?

Melanotan II is a synthetic cyclic analogue of alpha-melanocyte-stimulating hormone used in melanocortin-receptor research. Purvexis supplies it strictly as a research chemical, not for human or veterinary use.

What purity is your melanotan II?

Every melanotan II batch is tested by HPLC and mass spectrometry to ≥99% purity. A third-party certificate of analysis (COA) is available on request for the exact lot you receive.

Is melanotan II sold for human use?

No. melanotan II is supplied strictly as a research chemical for in-vitro and laboratory research use only. It is not a drug, food or dietary supplement, and it is not for human or veterinary use, diagnosis or treatment.

How should melanotan II be stored?

Lyophilised melanotan II is shipped at ambient temperature and is stable in transit. Store the sealed vial refrigerated at 2–8 °C, protected from light, for long-term storage; once reconstituted with bacteriostatic water, keep refrigerated and use within the window your protocol specifies.

How fast does melanotan II ship?

Every order ships free via USPS Priority Mail, typically arriving in 2–3 business days. Orders placed before the daily cut-off are packed the same business day, and tracking is emailed as soon as the label is generated.
