PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide α-MSH analogue with selective activity at MC3R and MC4R receptors in the central nervous system. It bypasses peripheral vascular pathways and acts on CNS-mediated arousal and behavioral pathways.
Research has characterized PT-141 in models of stress, appetite, reward, and sexual function across both sexes.
