Cardarine sarm is a popular PPARδ receptor agonist, often mislabeled as a SARM (Selective Androgen Receptor Modulator). It enhances endurance, fat loss, and metabolic efficiency by boosting stamina and oxidation of fats. Unlike SARMs, it doesn’t affect testosterone but is banned in sports due to its performance-enhancing effects. Users take it for cutting cycles and improved athletic performance, though its long-term safety remains controversial.
