What is PT-141?
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide melanocortin receptor agonist originally derived from Melanotan-2. Unlike its parent compound, PT-141 was specifically developed to target melanocortin-3 and melanocortin-4 receptors (MC3R/MC4R) with selectivity, making it a valuable research tool for studying central nervous system pathways involved in sexual function. For published research, see PubMed studies on PT-141{:target=“_blank” rel=“noopener”}.
PT-141 operates through a mechanism distinct from PDE5 inhibitors, acting centrally through melanocortin receptor activation rather than peripheral vasodilation.
Best-Peptides supplies research-grade PT-141 with guaranteed ≥99% purity and full analytical documentation.
How Does PT-141 Work?
Melanocortin Receptor Activation
- MC4R agonism - Primary central target
- MC3R activation - Secondary pathway
- CNS signalling - Hypothalamic pathways
- Downstream cascades - Oxytocin and dopamine modulation
Selectivity Profile
- Minimal melanogenesis - Unlike Melanotan-2
- Central mechanism - Not peripheral vasodilation
- Receptor-specific - MC3R/MC4R selectivity
- Dose-dependent - Predictable research responses
Neurochemical Effects
- Dopamine modulation - Reward pathway interaction
- Oxytocin release - Secondary signalling
- Hypothalamic action - Central integration
Research Applications

FAQ
PT-141 (Bremelanotide) is studied for melanocortin receptor activation, particularly MC3R and MC4R. Research focuses on sexual function pathways, central nervous system signalling, and melanocortin-mediated behaviour.
PT-141 is a metabolite of Melanotan-2 but acts selectively on MC3R/MC4R without significant melanogenesis. It was specifically developed to isolate the sexual function pathway from tanning effects.
PT-141 activates melanocortin-3 and melanocortin-4 receptors in the central nervous system, triggering downstream signalling cascades that differ from PDE5 inhibitor mechanisms.
Store lyophilised PT-141 at -20°C for long-term stability. Once reconstituted, keep at 2-8°C and use within 4 weeks. Avoid freeze-thaw cycles.
Our PT-141 is ≥99% pure as verified by HPLC. Each batch includes a Certificate of Analysis with purity data and mass spectrometry identity confirmation.
Yes, PT-141 is often studied in combination with other melanocortin system peptides. Researchers should consider receptor selectivity profiles when designing combination studies.
Reconstitute in sterile bacteriostatic water. Add solvent slowly along the vial wall and gently swirl to dissolve. PT-141 dissolves readily in aqueous solution.
PT-141 is available in 10mg vials for research applications.
