Overview PT-141 (Bremelanotide) is a synthetic melanocortin peptide derived from Melanotan-2, developed specifically for its potent effects on sexual arousal and libido. Unlike traditional sexual health compounds that work through the vascular system, PT-141 acts directly on the central nervous system — making it one of the most unique and targeted peptides studied in the field of sexual health research.
Mechanism of Action PT-141 works by binding to melanocortin receptors in the brain — specifically MC3R and MC4R — which are directly involved in regulating sexual arousal, desire, and motivation. By activating these central pathways, it stimulates dopaminergic activity in the hypothalamus, producing a neurological response that drives increased libido and sexual motivation in both male and female research models.
Research Applications Research on PT-141 has focused on hypoactive sexual desire disorder (HSDD) in both men and women, erectile dysfunction, and female sexual arousal disorder. It has been studied as a potential treatment for sexual dysfunction that does not respond to PDE5 inhibitors, and has shown efficacy in both pre-menopausal and post-menopausal female subjects in clinical trials.
Reconstitution & Storage PT-141 is supplied as a lyophilized powder. Reconstitute by adding bacteriostatic water slowly along the inner wall of the vial. Store unreconstituted vials in a cool, dry place — refrigeration is recommended. Once reconstituted, keep refrigerated.
PT-141 / Bremelanotide (10mg) — Libido Activation & Sexual Performance comes as a lyophilized powder and must be reconstituted before use.
You’ll need bacteriostatic water and insulin syringes,
both available for purchase as add-ons below.
