Cardarine, also known by its research code GW-501516, is one of the most talked-about compounds in the fitness and bodybuilding world. Although it's often grouped with SARMs (Selective Androgen Receptor Modulators), Cardarine is not actually a SARM. Instead, it’s a PPARδ receptor agonist, designed to enhance endurance, improve metabolism, and promote fat loss. https://www.sarmsup.co/products/cardarine-gw-501516
