Anderson Silva tested positive for two separate substances in his recent USADA drug test, MMA Fighting confirmed Friday.
The UFC legend had both methyltestosterone and a diuretic turn up in his system in a sample collected Oct. 26, sources confirmed. Combate was the first to report the news earlier this week.
Methyltestosterone is considered an anabolic agent in the UFC anti-doping policy, which carries a maximum suspension of two years. Silva, 42, has denied knowingly using any banned substances and is currently going through the adjudication process with USADA.
Per WebMD, methyltestosterone is a medication used by men whose bodies cannot produce enough testosterone and is similar to the natural testosterone a body produces.
