PT – 141

PT-141, also known as Bremelanotide, is a synthetic peptide and a research compound primarily investigated for its effects on sexual dysfunction. It is a melanocortin receptor agonist, specifically targeting melanocortin receptors 3 and 4, which are involved in various physiological processes, including sexual arousal. Unlike other treatments for sexual dysfunction, such as Viagra, which primarily act on vascular mechanisms, PT-141 works through the central nervous system, influencing sexual desire and arousal.
