PT-141 (Bremelanotide) — Melanocortin-4 Agonist Peptide
Explore neuroendocrine pathways of sexual arousal and vascular tone with PT-141, a cyclic heptapeptide that selectively activates MC-4R and MC-1R. Pre-clinical and Phase 2/3 data show rapid, transient increases in libido and penile/clitoral blood flow, making PT-141 a valuable tool for studying hypoactive sexual desire and erectile physiology.
