Melanotan II is a synthetic cyclic heptapeptide α-MSH analogue developed in academic research in the 1990s. It activates melanocortin receptors — primarily MC1R for pigmentation, with secondary effects via MC3R/MC4R on appetite and sexual behavior.
Compared with native α-MSH, MT-2 shows greater receptor affinity and pharmacological stability, with characterized pigmentation, anorectic, and pro-erectile effects in research models.
