About PT-141
PT-141 (Bremelanotide) is a synthetic melanocortin receptor agonist derived from Melanotan II. Unlike Melanotan II which primarily targets MC1R for tanning and weight effects, PT-141 preferentially targets MC3R and MC4R receptors in the brain, which are involved in sexual arousal in both men and women.
PT-141 is FDA-approved under the brand name Vyleesi for hypoactive sexual desire disorder (HSDD) in premenopausal women. In research settings, it has been studied for both male and female sexual dysfunction and arousal enhancement.
PT-141 is typically supplied in 10mg vials. Reconstituting with 2ml of bacteriostatic water gives a concentration of 5,000 mcg/ml. The typical research dose is 0.75–2mg (750–2000mcg), administered 45–90 minutes before anticipated activity via subcutaneous injection.
PT-141 has a half-life of approximately 12 hours. It is generally not recommended for daily use. Common side effects in research include transient nausea and flushing.
