cosmeticPT-141 is a research-use-only peptide. PeptideSource compares suppliers on purity, COAs, and price-per-mg.
Also known as: Bremelanotide, PT141, Bremenalotide
PT-141 acts by activating melanocortin receptors, specifically MC3R and MC4R, influencing sexual arousal pathways. Known as Bremelanotide, this peptide is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH), derived from research into hormonal regulation of sexual function. Initial studies emerged from efforts to address sexual dysfunction, with researchers exploring its potential to modulate physiological responses related to desire and arousal. Today, it is primarily studied for its effects on:
- Enhancing sexual arousal
- Treating sexual dysfunction
- Modulating melanocortin pathways
