Melanotan II (i) is a synthetic analogue of the naturally-occurring melanocortin peptide hormone α-melanocyte-stimulating hormone (α-MSH) that in usage has been shown to produce melanogenesis (part of the tanning process that produces darkening pigmentation in the skin) and have aphrodisiac effects in preliminary studies and clinical trials. Developed at the University of Arizona, it is a cyclic lactam analogue of α-MSH with the amino acid sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2.
