PT-141 peptide, also known generically as bremelanotide, is a synthetic heptapeptide and a melanocortin receptor agonist. It is derived from α-melanocyte-stimulating hormone and primarily targets central melanocortin receptors, specifically MC1R, MC3R, and MC4R. Among these, it exhibits the highest affinity for MC4R in the hypothalamic regions associated with sexual behavior.
