PT-141

PT-141 Peptide Description

PT-141 (bremelanotide) is a synthetic peptide analogue of alpha-melanocyte-stimulating hormone (α-MSH) that acts on melanocortin receptors, particularly MC3R and MC4R, in the central nervous system. PT-141 operates via a unique mechanism distinct from peripheral-acting agents like phosphodiesterase type 5 (PDE5) inhibitors. This action is believed to stimulate sexual arousal and desire by activating neurons in the hypothalamus, a key area involved in sexual function.
