PT 141 10mg
PT-141, or bremelanotide, is a synthetic peptide that activates melanocortin receptors in the brain to enhance sexual desire, currently FDA-approved for premenopausal women with hypoactive sexual desire disorder (HSDD), with off-label use in men for erectile dysfunction and low libido.
Mechanism of Action
PT-141 works centrally in the brain rather than targeting blood vessels. It is a melanocortin receptor agonist, primarily stimulating MC3R and MC4R in the hypothalamus and arcuate nucleus, key areas regulating sexual desire, arousal, and motivation
. Activation of these receptors promotes dopamine release and neural signaling associated with sexual motivation, making PT-141 distinct from PDE5 inhibitors like Viagra or Cialis, which improve sexual function via vascular mechanisms
.
