PT-141

The libido peptide

OtherResearchResearch compound — not for human use

Overview

Bremelanotide. Acts on melanocortin receptors in the brain to increase sexual desire and arousal in both men and women. Works centrally on the brain rather than through blood flow mechanisms — a fundamentally different approach from other treatments.

Key Benefits

  • Increased sexual desire in men and women
  • Improved arousal response
  • Central brain mechanism — works differently from PDE5 inhibitors
  • Effective for both sexes
  • FDA approved (Vyleesi) for HSDD in premenopausal women

How to Use
