Description
Overview
PT-141 (Bremelanotide) is a melanocortin receptor agonist, specifically MC3R and MC4R, that works centrally in the brain rather than through vascular mechanisms like PDE5 inhibitors (Viagra). This means it activates desire and arousal at the neurological level, working for both men and women. Originally developed from a sunless tanning peptide (MT-II), researchers noted powerful sexual side effects, which led to dedicated development. FDA-approved as Vyleesi for female HSDD. It works within 30-60 minutes and effects last 8-12 hours.
