PT-141 (bremelanotide) is a synthetic peptide derived from Melanotan II that acts primarily at the MC4 receptor in the central nervous system. Unlike vasodilator-class compounds, PT-141 produces its observed effects through the CNS rather than through blood flow. The FDA approved bremelanotide for hypoactive sexual desire disorder in pre-menopausal women in 2019 under the brand Vyleesi; outside that indication, the compound remains a research tool for studying MC4-mediated pathways. Produced under documented quality control. For research use only.
