PT-141, also known as Bremelanotide, is a synthetic cyclic heptapeptide and analog of alpha-melanocyte stimulating hormone (α-MSH). It has been studied in research models for its activity at melanocortin receptors, specifically MC3R and MC4R, which are expressed in the central nervous system. Published research has examined PT-141’s role in melanocortin receptor signaling pathways, its observed effects on hypothalamic activity in animal models, and its interactions with dopaminergic and serotonergic systems. PT-141 is distinct from MT-1 and MT-2 in its receptor binding profile and research applications. This product is supplied as lyophilized powder for laboratory reconstitution by qualified researchers.
