PT-141
10mg · £29.99
PT-141 is bremelanotide, a melanocortin receptor agonist derived from the alpha-MSH family. Unlike most compounds in this catalogue it has been through full regulatory approval elsewhere: Dhillon and Keam documented its first approval in Drugs in 2019.
That approval is for a licensed medicine in another jurisdiction. Material supplied by BSR is research material, not that product, and is not authorised for use in people.

Mechanism in the literature
Bremelanotide is a parenterally administered melanocortin receptor agonist. The melanocortin system is distinct from the incretin and growth hormone pathways covered elsewhere in this catalogue.
The clinical literature concerns an approved medicine used under prescription. It is not guidance for research material, and nothing here should be read as suggesting use in people.
Handling and reconstitution
Supplied lyophilised at 10mg and 20mg. Room temperature before reconstitution, diluent down the vial wall, gentle swirling.
Storage and stability
Lyophilised at -20°C, protected from light. Reconstituted solution refrigerated and used within a short window.
Common questions

They are the same compound. PT-141 is the development code and bremelanotide the approved name.
