What it is

A cyclic melanocortin-receptor agonist derived from alpha-MSH, studied in the nervous system's desire and arousal pathways rather than in blood flow.

PT-141 is studied as a melanocortin agonist that signals through the central nervous system, unlike compounds that act on blood flow.

Melanocortin receptors. Studied as an agonist at the MC3 and MC4 receptors.

Desire and arousal pathways. Researched in the nervous system's signalling for sexual desire and arousal.
