Description
PT-141, also known as Bremelanotide, is a synthetic cyclic peptide derived from Melanotan II that acts on the melanocortin receptor system, specifically MC3R and MC4R in the central nervous system. Unlike phosphodiesterase inhibitors, it works through neurological pathways rather than vascular mechanisms. PT-141 is studied for its effects on sexual arousal and libido modulation in both male and female research models, offering a unique mechanism of action in the field of sexual function research.
