What it does

PT-141 (Bremelanotide) activates melanocortin MC3R and MC4R receptors in the hypothalamus — the brain's arousal centre. Unlike PDE5 inhibitors (Viagra, Cialis) that work on blood flow, PT-141 works on the central nervous system to stimulate genuine sexual desire and arousal. This makes it effective for both men and women, including cases with psychological components.

The mechanism is fundamentally different from every other sexual health compound on the market — it creates desire rather than just enabling the physical response.
