Product Description

PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It primarily acts on melanocortin-4 receptors (MC4R) in the central nervous system. This peptide has been studied extensively in neuroendocrine research for its unique mechanism of action distinct from peripheral vasodilatory pathways.
