Buy PT-141 10mg | Bremelanotide Peptide for Research

PT-141 (10mg), also known as Bremelanotide, is a synthetic heptapeptide analog of α-MSH (alpha-melanocyte-stimulating hormone). It is widely studied as a melanocortin receptor agonist, primarily targeting MC4R and MC3R receptors. In research settings, PT-141 is investigated for its effects on sexual arousal, libido, and central nervous system-mediated sexual function, independent of vascular mechanisms. It serves as a valuable tool in neuroendocrine, behavioral, and sexual dysfunction research models.

What is PT-141?

PT-141 (Bremelanotide) is a cyclic heptapeptide derived from Melanotan II by removing the C-terminal amide and modifying the structure to reduce tanning effects while retaining strong melanocortin receptor activity. Unlike PDE5 inhibitors (such as sildenafil), PT-141 acts centrally in the brain via the melanocortin pathway to modulate sexual arousal and desire.

It is one of the few compounds studied for its potential to influence both male and female sexual function through central nervous system pathways rather than direct vascular effects.

Mechanism of Action in Research

In experimental models, PT-141:

• Acts as a potent agonist at melanocortin receptors (especially MC4R)
• Activates neural pathways in the hypothalamus and limbic system involved in sexual behavior
• Enhances sexual arousal and desire without requiring sexual stimulation
• Modulates dopamine release in reward-related brain areas
• Shows minimal peripheral vascular effects compared to other sexual function compounds

Key Research Areas

PT-141 is primarily explored in:

• Central regulation of sexual arousal and libido
• Male and female sexual dysfunction models
• Neuroendocrine studies on melanocortin signaling
• Behavioral pharmacology and reward pathway research
• Comparative studies with other melanocortin agonists

Research Applications

The 10mg vial supports:

• In-vivo behavioral and sexual function studies
• Melanocortin receptor binding and activation assays
• Neuroendocrine and hypothalamic research
• Dose-response and chronic administration experiments

Reconstitution is typically performed with bacteriostatic water for precise laboratory dosing.
