Cardarine GW-501516

An experimental endurance compound popular in fitness circles despite being banned in sports, working by changing how the body burns fat for energy. Long-term studies in rodents found it caused cancer in multiple organs, which is why its original human development program was shut down.

Also known as GW501516, Endurobol, GW 501516, 7I2HA1NU22, CHEBI:73726, RefChem:574663, GW 1516, GW 501,516
