Sexual health & libido support
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analogue of alpha-MSH that acts centrally on melanocortin receptors (MC3R and MC4R) in the hypothalamus. Unlike PDE5 inhibitors, it works via the central nervous system to enhance sexual arousal and desire in both men and women, and has received FDA approval for hypoactive sexual desire disorder.

Mechanism of Action
PT-141 is a cyclic heptapeptide metabolite of Melanotan II that acts as a non-selective melanocortin receptor agonist. Unlike PDE5 inhibitors, it acts centrally via MC3R and MC4R in the hypothalamus to modulate sexual arousal pathways. Research investigates its mechanism in hypoactive sexual desire and central arousal neuroscience.
