PT-141

PT-141 (Bremelanotide) is a synthetic melanocortin receptor agonist derived from the alpha-MSH peptide family. It has been widely studied for its activity on central nervous system pathways involved in sexual desire, arousal, and behavioral signaling. Unlike agents that act primarily through vascular mechanisms, PT-141 works through neural melanocortin receptors, particularly MC3R and MC4R, making it a unique subject of interest in sexual-function research. Scientific investigations have explored PT-141’s ability to modulate desire and arousal by activating specific brain pathways that influence motivation, reward, and intimate connection. Research in both men and women has examined its effects on libido, central arousal…
