PT 141

PT-141 – Overview

PT-141 (Bremelanotide) is a peptide that targets sexual function by acting on the central nervous system rather than directly on the reproductive organs. It is studied for enhancing libido and sexual arousal in both men and women.

How PT-141 Works

PT-141 works by:

✔ Activating melanocortin receptors

• Binds to MC3 and MC4 receptors in the brain

• Stimulates sexual desire and arousal signals

✔ Central nervous system modulation

• Works through the brain rather than directly affecting hormones

• Enhances natural sexual response

✔ Promoting vascular response

• May increase blood flow indirectly through neurological signaling

• Supports arousal and sexual readiness
