PT-141 (Bremelanotide)
The most researched peptide for its role in sexual function and desire.
Unlike other compounds that act on blood flow, PT-141 acts on central nervous system receptors involved in desire.
What is it?
A synthetic peptide derived from the hormone α-MSH, designed to interact with melanocortin receptors in the brain. It acts on the central nervous system to study its role in desire and sexual response.
How does it work?
It activates melanocortin receptors, especially MC4R, which are linked to sexual desire. Unlike medications that improve circulation, it aims to act on the brain's mechanisms of arousal.
What science is researching
Observed results
Results may vary from person to person and depend on the context of the study.
- Increased sexual desire in some participants
- Improved sexual response in studied populations
- Interest in its action independent of blood flow
- Potential usefulness in female and male sexual function
What it does NOT do
- Does not guarantee a sexual response in everyone
- Does not replace medical evaluation
- Is not a universal treatment for every sexual dysfunction
- Its use depends on each country's regulations

Quick summary
PT-141 was developed from research on Melanotan II, when it was observed that some of its effects were linked to sexual-function receptors rather than to pigmentation.
