Class:
Synthetic cyclic heptapeptide / non-selective melanocortin receptor agonist
Status:Research compound — NOT FDA approved. FDA issued warning letters. WADA banned substance.
Mechanism:A synthetic cyclic heptapeptide (Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH₂) analog of α-MSH. Melanotan II is a high-affinity non-selective agonist at MC1R, MC3R, MC4R, and MC5R. MC1R activation induces melanogenesis (skin darkening/tanning); MC4R activation affects sexual function, appetite suppression, and energy homeostasis. Carries significant safety risks including nausea, hypertension, and priapism.
