SKU: pt-141-10mg
PT-141 (bremelanotide) is a synthetic melanocortin receptor agonist derived from alpha-melanocyte-stimulating hormone that stimulates sexual arousal through central nervous system pathways. Unlike vascular-based treatments, it targets MC-4R and MC-1R receptors to address sexual desire disorders in both males and females.
