PT-141 (Bremelanotide) is a cyclic heptapeptide melanocortin receptor agonist with a molecular weight of 1025.18 Da and ≥98% purity. It acts primarily on MC3R and MC4R receptors in the central nervous system. Originally derived from Melanotan II, PT-141 is studied for its effects on melanocortin signaling pathways involved in sexual function and arousal responses. Peak Revival Plus provides PT-141 as a lyophilized powder for in-vitro laboratory research applications only.

Frequently Asked Questions
Common questions about PT-141 (Bremelanotide). Can't find what you're looking for? Contact our research support team.
PT-141 (Bremelanotide) is a synthetic peptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It acts on melanocortin receptors (MC3R and MC4R) in the central nervous system. It is studied in research related to melanocortin receptor signaling and sexual function pathways.
Reconstitute with bacteriostatic water. For a 10mg vial, add 2mL of BAC water for a 5mg/mL concentration. Inject slowly along the vial wall and swirl gently until dissolved. Store reconstituted solution at 39°F (4°C) and use within 7 days.
Lyophilized PT-141 maintains ≥95% stability for 24+ months at -4°F (-20°C). After reconstitution, store at 39°F (4°C) and use within 7 days.
Every batch is independently tested by accredited third-party laboratories with full Certificates of Analysis (COA) available on request.
