CardarineBenefits, Dosage & Interactions
Also known as: GW-501516
Cardarine (GW501516) is a PPAR-delta agonist developed in the 1990s for dyslipidaemia and metabolic disease, and frequently mislabelled online as a SARM — it is not one, and it does not bind androgen receptors. Research on Cardarine focuses on blood sugar control, heart and circulatory health, and weight loss.
How much Cardarine do people take?
No human dose-finding trial was published; development was halted after rodent carcinogenicity findings. Route reported: Oral in the animal work. Frequency reported: Daily in the rodent protocols. These are amounts documented in the cited studies and labels for Cardarine — they are reported for reference, not a recommendation. Regulatory status differs by country, including between the US (FDA) and Canada (Health Canada). Confirm any amount with a licensed clinician before you take it.

Quick answer
Cardarine (GW501516) is a PPAR-delta agonist developed in the 1990s for dyslipidaemia and metabolic disease, and frequently mislabelled online as a SARM — it is not one, and it does not bind androgen receptors. Development was halted after long-term rodent studies produced tumours across multiple organ systems at a range of doses. It is banned by WADA, is not approved for human use anywhere, and is sold only as an unregulated research chemical.
