Melanotan II Research Compound (MT2)

"Premium grade Melanotan II validation."

Melanotan II is a synthetic cyclic heptapeptide with the sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2, joined by a 23-membered lactam bridge, and acts as a non-selective melanocortin receptor agonist. It was reported to be markedly more potent and longer-acting than alpha-MSH in melanotropic bioassays (Al-Obeidi et al., J Med Chem 1989, PMID 2555512). Melanotan II research peptide is supplied lyophilized at ≥99% purity verified by HPLC, with identity confirmed by mass spectrometry and a batch-specific Certificate of Analysis (COA) included. Store lyophilized powder at −20 °C, protected from light and moisture. For laboratory research use only — not for human or animal consumption.
