PT-141
Research use only.
PT-141 (Bremelanotide) is a lab-made peptide studied for its effects on sexual desire and arousal. It works through the brain rather than the blood vessels, which sets it apart from many other options.
What it is studied for
- Libido: its effect on sexual desire in men and women.
- Arousal: how it acts through brain pathways.
About PT-141
PT-141 (bremelanotide) is a cyclic heptapeptide melanocortin-receptor agonist, derived from Melanotan II, with activity mainly at MC3R and MC4R. Unlike most peptides it is studied for effects in the central nervous system, which makes it a distinct area of neuroendocrine research.
Key research areas
- Melanocortin receptors — MC3R/MC4R agonism in the central nervous system.
- Sexual-function research — CNS pathways involved in arousal and libido models.
- Neuroendocrine research — Hypothalamic signalling studies.
- Melanotan comparisons — How it differs from its parent compound, Melanotan II.
