What Cardarine is
A PPAR-delta agonist that GSK abandoned in 2007 after long-term rodent studies produced cancers in multiple organs; still sold widely for endurance and fat loss despite the signal and a WADA ban.
Cardarine shifts muscle toward fat oxidation and in the 2008 Cell paper combined with training to raise mouse endurance. Development stopped when two-year rodent studies showed tumors in the liver, bladder, stomach, skin, thyroid and other tissues.
Mechanism: PPAR-delta agonism that upregulates fatty-acid oxidation genes in skeletal muscle.
Regulatory history: Never approved; development halted for carcinogenicity
