PT-141 (10mg)

PT 141 (Bremelanotide) is a synthetic cyclic heptapeptide melanocortin receptor agonist derived from α-MSH. It acts on sexual dysfunction by activating central MC3R/MC4R pathways. For males, it improves erectile function through corpus cavernosum smooth muscle relaxation. For females, it enhances sexual desire via CNS-mediated regulation of libido. Its mechanism circumvents traditional PDE5-inhibitor pathways, making it effective for PDE5-resistant cases. PT 141 has demonstrated rapid onset of action within minutes post-administration. Preclinical and clinical evaluations have shown it to be well-tolerated overall.
