PT-141 10mg — Self-Injection Pen

PT-141 (Bremelanotide) is a melanocortin-receptor agonist that acts on the nervous system rather than on blood flow, so it works on desire itself. Researchers study it for sexual arousal and libido in both men and women. Delivered as a prefilled, click-dose self-injection pen — compounded in a US-licensed pharmacy and shipped cold-chain. Refrigerator-stable; store at 2–8°C. For use under licensed-provider supervision.

Prescription therapy. A licensed provider reviews every order before it ships — your free consultation is included.
