Overview

PT-141 (Bremelanotide) for research use only, is a synthetic cyclic heptapeptide and melanocortin receptor agonist derived from the α-MSH peptide family. It has been studied in research contexts involving melanocortin signalling pathways and central nervous system receptor activity.

This vial contains 10mg of PT-141, supplied lyophilised (freeze-dried), research grade, in a sealed vial. Each batch is supplied with a Certificate of Analysis confirming purity and identity testing carried out at the point of manufacture, published on this page before sale.

PT-141 is investigated in research settings including melanocortin receptor pharmacology, neuroendocrine signalling, central nervous system pathway studies, and receptor binding models. Velyx makes no health claims about this compound.
