PT-141

Also known as Bremelanotide

A melanocortin-receptor agonist studied for sexual arousal and desire, acting through the central nervous system rather than the vascular system.

Melanocortin pathwayCNS arousal

What it is

PT-141, or Bremelanotide, is a melanocortin peptide derived from the same family as Melanotan 2 — but optimised toward the sexual-function receptor rather than pigmentation. It is notable for working through the brain.

How it's thought to work

PT-141 activates MC4R receptors in the central nervous system, influencing the neural pathways behind sexual desire and arousal. Unlike vascular drugs, it acts on desire centrally rather than purely on blood flow.

Potential health benefits

Studied for:

  • Increased sexual desire and arousal in both men and women.
  • A mechanism that may help where blood-flow-based approaches don't.

What the research says

Bremelanotide has been through human clinical trials and is approved in some regions for a specific form of low sexual desire in women — giving it a real clinical evidence base. Reported side effects include nausea and transient flushing.

Considerations

Sold here as a research compound. Discuss with a qualified clinician, especially if you have blood-pressure concerns.
