Melanotan II Research Peptide

Yes. Every batch of Melanotan II is tested by an independent third-party laboratory using HPLC and MS-UPLC, confirming purity and mass identity before the batch is released. Pure Peptides does not test its own material.

Yes. The Certificate of Analysis for the batch currently in stock can be viewed and downloaded directly on this page, before you place an order. Each certificate states the batch number, the measured purity, and the date of analysis, and can be verified independently with the issuing laboratory using the report number it carries.

It means Melanotan II is supplied for in-vitro laboratory research and for no other purpose, and must not be administered to humans or animals. Melanotan II is legal to purchase in the United States for in vitro and non-clinical laboratory research. It has no FDA approval and no approved human use. Melanotan II is not a scheduled substance under the Controlled Substances Act. Sold strictly for qualified research use, not human or veterinary administration.

Melanotan II ships from US stock with cold-chain packaging and full tracking; orders placed before noon EST on business days are typically dispatched the same business day. On arrival, store the lyophilized powder at -20°C or below, dry and protected from light.

A substantial part of the indexed literature on this compound consists of case reports and clinical toxicology reports arising from unregulated use, rather than receptor pharmacology. Published reports describe melanoma in situ and changes in existing moles, including one case in which sequential video dermoscopy recorded changes that made a mole difficult to distinguish from a melanoma. Others describe severe muscle breakdown with intensive-care admission, and a prolonged painful erection that required surgery after standard first-line measures failed. Each is a single case. Case reports do not establish incidence and they do not establish causation, but they are what the literature contains.

One published study bought vials sold as injectable tanning products from three online shops and analyzed them by liquid chromatography and tandem mass spectrometry. Each shop claimed 10 mg of Melanotan II per vial. The measured content ranged from 4.32 to 8.84 mg. Samples from two of the three shops contained unidentified impurities of between 4.1 and 5.9 per cent. A separate study identified Melanotan II and bremelanotide in samples confiscated by police alongside anabolic steroids and stimulants.

No. Bremelanotide is a further analogue derived from Melanotan II and is listed separately on this site. A separate alpha-MSH analogue again, afamelanotide, is a different molecule from both. No result reported for either is a result for this one.
