MT-2 (Melanotan II, also known as MTII or Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH₂) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). This research compound has garnered extensive scientific interest for its potent, non-selective agonism at multiple melanocortin receptors (MC1R, MC3R, MC4R, MC5R), with particularly strong activity at MC1R and MC4R. Preliminary and advanced preclinical studies indicate that MT-2 may robustly stimulate melanogenesis (skin and hair pigmentation), induce erections via central melanocortin pathways, modulate sexual behavior, suppress appetite, and influence energy homeostasis. Researchers utilize MT-2 in laboratory and animal models to investigate mechanisms of melanocortin receptor signaling, pigmentation biology, sexual function, obesity, and neuroendocrine regulation. As a research-grade compound, MT-2 is intended exclusively for in vitro and animal studies. Scientists value its enhanced potency, prolonged duration of action compared to native α-MSH, and its utility in dissecting the pleiotropic effects of melanocortin receptor activation across dermatological, reproductive, and metabolic research domains.
