PT-141
10mg
PT-141 (Bremelanotide) is a synthetic peptide analog of alpha-MSH (melanocyte-stimulating hormone). It has been studied for its effects on sexual arousal and desire, acting primarily through activation of the MC4R receptor in the central nervous system. It has been researched in contexts of hypoactive sexual desire disorder (HSDD) and erectile dysfunction.
How to Order
Preclinical Research Areas
- ●Activation of MC4R pathways (melanocortin system)
- ●Sexual arousal and desire enhancement (non-vascular mechanism)
- ●Research applications for HSDD
- ●No vasoconstrictive effects (unlike PDE-5 inhibitors)
- ●Possible effects on mood and motivation
Research doses typically range from 0.5–2.0 mg, administered via subcutaneous injection approximately 45–60 minutes before anticipated activity. Onset of effects can vary by individual. The peptide has a relatively short half-life, typically studied for acute dosing rather than daily use. Side effects observed in research include nausea (usually mild and transient), flushing, and headache in some subjects.

PT-141 is unique among sexual health compounds in that it does not act on vascular smooth muscle (like PDE-5 inhibitors) but instead activates central melanocortin pathways. The MC4 receptor is involved in reward and motivation circuits, and PT-141 appears to modulate these pathways to enhance sexual desire and arousal. The peptide has demonstrated efficacy in both male and female subjects in clinical research. It was approved by the FDA in 2019 for HSDD in women (as Vyleesi).
