What did Jones test positive for, a performance enhancer or something illegal?
Chael Sonnen said on the Joe Rogan Podcast Jones was caught with 2 estrogen blockers in his system, no performance enhancing per se, but synthetic testosterone masking agents. If I am not wrong I think it was Tamoxifen and Clomid.
Basically trying to lower his estrogen levels after using a full testosterone cycle, that is what he was busted with.
