PT-141

$51.74

PT-141, also known as Bremelanotide, is a high-purity synthetic cyclic heptapeptide, a derivative of alpha-melanocyte-stimulating hormone (α-MSH), designed exclusively for laboratory research. This peptide acts as a potent, non-selective agonist of melanocortin receptors (primarily MC3R and MC4R), making it a valuable tool for investigating neuroendocrine signaling, appetite regulation, and inflammatory pathways. Supplied as a lyophilized powder for reconstitution, PT-141 provides researchers with a precise compound to study its effects on metabolic and physiological processes in experimental models.

Research Applications:

PT-141 is extensively studied in preclinical research for its ability to modulate melanocortin signaling, which influences appetite, energy expenditure, and inflammation in cellular and animal models. Investigations focus on its activation of MC4R to suppress appetite and increase energy expenditure, making it a key compound for weight loss studies. Research also explores its anti-inflammatory properties and potential to enhance tissue repair, which may support muscle recovery by reducing exercise-induced inflammation and promoting cellular repair. Its role in regulating energy homeostasis and metabolic health further supports its use in health optimization research.
