PT-141 10mg Research Peptide
PT-141, also known as bremelanotide, is a cyclic heptapeptide melanocortin receptor agonist derived from MLT II. It is supplied as a 10mg lyophilized research vial.
Research Applications
PT-141 is studied for its activity at the MC3 and MC4 melanocortin receptors in the central nervous system. Lab research focuses on hypothalamic melanocortin signaling and how it differs from peripheral melanocortin activity.
Why Researchers Choose It
- Central melanocortin (MC3R/MC4R) research tool
- Compare with MLT I and MLT II
- Lyophilized for stability in storage and transit
- Batch-tracked with third-party COA testing
