PT-141 (Bremelanotide) is a synthetic peptide analogue of α-melanocyte-stimulating hormone (α-MSH) designed to activate melanocortin receptors (MC3R/MC4R) in the hypothalamus. Unlike peripheral PDE-5 inhibitors, PT-141 works centrally to influence sexual arousal, libido, and related neuroendocrine pathways.
Activates central melanocortin pathways, enhancing sexual desire and performance
Modulates dopaminergic signaling, parasympathetic tone, and nitric-oxide–mediated vasodilation
Influences mood, energy, and central nervous system arousal
Primarily researched for sexual dysfunction in men and women, including hypoactive sexual desire disorder (HSDD)
Men: 1–2 mg subcutaneously per administration; may increase up to 4 mg for research purposes
