What is PT-141 (Bremelanotide)?
PT-141, also known as Bremelanotide, is a synthetic peptide designed to enhance sexual desire and arousal in both men and women. Unlike traditional medications for erectile dysfunction (which act on blood vessels), PT-141 works directly on the central nervous system, targeting the brain’s hypothalamic pathways to naturally increase libido.
How Does PT-141 Work?
PT-141 activates melanocortin-4 receptors (MC4R) in the brain areas linked to sexual desire, mood, and motivation.
This central action promotes the release of neurotransmitters such as dopamine, which plays a key role in pleasure and arousal.
In men, PT-141 enhances erections and sexual satisfaction, even for those unresponsive to PDE-5 inhibitors like Viagra or Cialis.
In women, it helps increase sexual desire and improve satisfaction during intimacy.
