About PT-141

PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analogue of α-MSH that acts as a non-selective melanocortin receptor agonist with affinity for MC1R, MC3R and MC4R. Laboratory research has investigated its activity at central melanocortin receptors and its association with arousal-related neural pathways in animal models. Supplied as a lyophilised powder for in vitro research use only.
