THE DESIRE ACTIVATOR
PT-141
FDA-approved desire enhancement that works through the brain
Also known as: Bremelanotide; Vyleesi; Rekynda
Overview
PT-141 (bremelanotide) is FDA-approved as Vyleesi for treating hypoactive sexual desire disorder (HSDD) in women. Unlike Viagra which works on blood flow, PT-141 works centrally in the brain by activating melanocortin receptors. This means it actually increases desire, not just physical response. It also works for men and has neuroprotective properties.
