Pt 141 mechanism of action?

In the research literature, PT-141 is described as a cyclic heptapeptide melanocortin receptor agonist, a metabolite-like analogue of Melanotan II with a C-terminal acid, used in melanocortin receptor research. It is classed as a cyclic peptide. This describes its use as a laboratory research tool only, not any effect in people. Sable Peptides supplies it for laboratory research use only; it is not for human consumption.
