What is PT-141?
PT-141 (bremelanotide) is an FDA-approved peptide, sold under the brand name Vyleesi, used to treat low sexual desire in premenopausal women. Unlike drugs that work on blood flow (like Viagra), it works directly in the brain to increase sexual desire and arousal. It’s also used off-label in men to help with low libido and erectile difficulties.
