Peptides for Erectile Dysfunction

PT-141 works through the nervous system, not blood vessels — offering an alternative for men who don't respond to PDE5 inhibitors.

Overview

PT-141 (Bremelanotide) is unique among ED treatments because it works through melanocortin receptors in the brain rather than the vascular system. This makes it effective for men who don't respond to PDE5 inhibitors like Viagra or Cialis. While FDA-approved for female sexual dysfunction (HSDD), it is widely used off-label for male ED.

Key Benefits

  • Works through nervous system, not blood vessels
  • Effective for PDE5 inhibitor non-responders
  • Enhances desire alongside physical arousal
  • No interaction with nitrates or blood pressure meds
  • Available as injection or nasal spray

Frequently Asked Questions

How does PT-141 compare to Viagra?

Viagra (sildenafil) works by relaxing blood vessels to increase blood flow. PT-141 works through melanocortin receptors in the brain, enhancing both desire and physical arousal. PT-141 is a good option for men who don't respond to Viagra/Cialis or who can't take them due to blood pressure medications or nitrate use.

Is PT-141 FDA approved?

PT-141 (Bremelanotide, brand name Vyleesi) is FDA-approved for hypoactive sexual desire disorder (HSDD) in premenopausal women. For male erectile dysfunction, it is used off-label. Many providers prescribe it for men based on clinical evidence and practice experience.
