This category features melanocortin peptides, a class of molecules that act as agonists for melanocortin receptors (MCRs). These compounds, including Melanotan and PT-141, are widely used in preclinical research. Scientists use them to investigate a range of physiological processes. Key research areas include skin pigmentation (tanning), sexual arousal, and appetite regulation. They provide researchers with precise tools to explore the diverse functions of the melanocortin system. All products are for in-vitro laboratory research only.
