PT-141 (Bremelanotide) — Buy in Canada

What is PT-141?

PT-141 (Bremelanotide) is a synthetic cyclic peptide analogue of alpha-MSH (alpha-melanocyte stimulating hormone) that acts on melanocortin receptors MC3R and MC4R in the central nervous system. Unlike vasodilatory approaches to sexual dysfunction research, PT-141 works via CNS pathways — making it one of the only peptides studied for centrally-mediated sexual arousal in both male and female research models. It was FDA-approved in 2019 as Vyleesi for hypoactive sexual desire disorder in premenopausal women.

VELTRIDE supplies PT-141 10mg lyophilized powder at ≥98% HPLC-verified purity with Certificate of Analysis, shipped discreetly across Canada from West Kelowna, BC. Researchers studying melanocortin pathways, sexual function, and CNS-mediated arousal use PT-141 as a well-characterized reference compound.

Research Highlights

• Acts on MC3R and MC4R receptors — CNS-mediated mechanism distinct from PDE5 inhibitors
• FDA-approved (Vyleesi) for hypoactive sexual desire disorder in women
• Studied in both male and female sexual function models
• Potential applications in erectile dysfunction research via central arousal pathways
• Melanocortin receptor activity also studied for energy balance and mood
• Half-life approximately 2-4 hours — controllable dosing windows in research
• Complementary to Melanotan-2 research with more CNS-selective profile

PT-141 vs Melanotan-2

PT-141 is a metabolite of Melanotan-2 with a more CNS-selective profile and reduced tanning activity. Researchers studying sexual function specifically may prefer PT-141; those studying tanning, appetite suppression, and broader melanocortin activity may select Melanotan-2. Both are available from VELTRIDE Canada.
