PT-141, also called Bremelanotide, is a synthetic peptide that acts as a melanocortin receptor agonist. It is studied in laboratory research and supplied for research use only.
What PT-141 is
PT-141 is a synthetic peptide derived from the melanocortin peptide family. As a melanocortin receptor agonist, it is designed to interact with receptors in that system, which is the basis for the research interest in it.

How it is studied
In the laboratory, PT-141 is studied as a research compound within melanocortin-system research. Like any research peptide, it is a study tool, not a therapeutic, and it is not approved or intended for human use.
Browse research-grade peptides
Every Axis compound is third-party tested to 99.4%+ purity, with a certificate of analysis on every batch.
What to look for
Because peptide identity and purity cannot be judged by eye, a research-grade PT-141 should ship with a batch-specific certificate of analysis. It is sometimes compared to Melanotan II, another melanocortin peptide.

A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
