CAS: 189691-06-3
PT-141 (Bremelanotide) is a cyclic melanocortin peptide and metabolite of Melanotan II. FDA-approved (Vyleesi) for hypoactive sexual desire disorder. Activates MC3R and MC4R centrally to produce sexual arousal independent of vascular mechanisms. 99.0% HPLC purity.
Specifications
For laboratory research use only. Not for human consumption.
Mechanism of Action
MC3R/MC4R agonism in hypothalamic and limbic regions drives sexual arousal via central neural pathways rather than the peripheral vascular mechanism of PDE5 inhibitors, making it active in both sexes.
Research FAQ
What distinguishes PT-141 from Melanotan II?
PT-141 lacks the ring-opening that gives Melanotan II broad melanocortin activity. PT-141 is more selective for MC3R/MC4R (CNS sexual arousal) with less MC1R (tanning) activity.
