PT-141 (Bremelanotide) is a lab-grade peptide that targets melanocortin receptors in the brain, triggering sexual arousal and increasing sexual desire in both research models and human trials.

Why Researchers Use PT‑141

• Stimulates sexual desire – Acts via MC‑4R in the hypothalamus to increase libido and arousal 

• Proven in trials – Tested in Phase 2/3 studies and FDA-approved (as Vyleesi) for female Hypoactive Sexual Desire Disorder 

• Unique mechanism – Works on central nervous pathways, not blood flow, making it suitable for studies beyond ED 

Simple Science Explanation PT-141 imitates α‑MSH, binding MC‑4R in the brain to stimulate sexual response without affecting blood pressure or circulation directly.

FAQs

Q: How fast does it work? A: Effects on arousal typically appear ~45 minutes after subcutaneous injection 

Q: Is it safe? A: Well-tolerated in trials. Common side effects include nausea, flushing, and

Q: What makes it different from other libido peptides? A: It works through central melanocortin receptors (MC‑4R/MC‑1R), offering a unique mechanism separate from blood flow–based treatments like sildenafil
