PT-141 (Bremelanotide) is a synthetic melanocortin peptide that activates brain receptors to enhance sexual desire in both men and women. Unlike PDE5 inhibitors (Viagra, Cialis), PT-141 works neurologically — increasing sexual motivation from the hypothalamus and limbic system. FDA-approved as Vyleesi (1.75 mg) for hypoactive sexual desire disorder in pre-menopausal women. Effects begin 45–90 minutes after injection and last 6–12 hours. Effective for both sexes.
