PT-141 (Bremelanotide) – Peptide for Libido & Sexual Function

Product Name: PT-141
Generic Name: Bremelanotide
Form: Injectable (subcutaneous) or nasal spray
Category: Melanocortin receptor agonist
Primary Use: Treatment of sexual dysfunction, libido enhancement

Description:

PT-141 (Bremelanotide) is a synthetic peptide derived from Melanotan II. Unlike traditional treatments for sexual dysfunction (such as Viagra or Cialis), which work by affecting blood flow, PT-141 acts directly on the nervous system by stimulating melanocortin receptors, especially MC4-R, to enhance sexual arousal and desire.

It is FDA-approved in the U.S. (under the brand name Vyleesi) for treating hypoactive sexual desire disorder (HSDD) in premenopausal women and is also used off-label by men for erectile dysfunction (ED) and libido enhancement.

Key Benefits:

• Increases sexual arousal and desire

• Works in both men and women

• Rapid onset (typically within 30–60 minutes)

• Doesn’t rely on the vascular system — neuroactive mechanism
