Werdum, 41, tested positive for trenbolone and its metabolite epitrenbolone following an out-of-competition urine test conducted on April 25, 2018. Trenbolone is a non-Specified Substance in the class of Anabolic Agents and prohibited at all times under the UFC Anti-Doping Policy, which has adopted the World Anti-Doping Agency Prohibited List. Werdum’s two-year period of ineligibility, the standard sanction for a first offense involving a non-Specified Substance, began on May 22, 2018, the date his provisional suspension was imposed.
Apparently trenbolone is used for getting cut and isn't very good for your cardio. At least a year since Jon Jones popped and still no word.
