Product Description (Professional Use)

PT-141 (Bremelanotide) is a synthetic cyclic peptide belonging to the melanocortin receptor agonist class.

It is structurally derived from α-melanocyte-stimulating hormone (α-MSH) and has been modified to enhance receptor selectivity and biological stability.

In research settings, PT-141 is primarily studied for its interaction with the central nervous system via melanocortin pathways, rather than vascular mechanisms.

This differentiates it from traditional compounds that act through nitric oxide pathways.

PT-141 supports erectile function indirectly by activating brain pathways that trigger sexual arousal, rather than directly increasing penile blood flow.
