Chael Sonnen fails random drug test UFC light heavyweight Chael Sonnen has failed a random drug test and will not fight Vitor Belfort at UFC 175 on July 5. The Nevada State Athletic Commission randomly tested Sonnen last month while he was in Las Vegas to attend a UFC news conference. Results confirmed the presence of two illegal substances, anastrozole and clomiphene. NSAC chairman Francisco Aguilar confirmed the test results to ESPN.com on Tuesday. UFC officials also acknowledged the situation. "UFC officials acknowledge irregularities in a recent random test," the promotion stated. "Chael is planning on addressing the matter this afternoon." The substances Sonnen tested positive for are classified as antiestrogenic. Anastrozole is used to treat early stages of breast cancer. Clomiphene is used in cases of female infertility. link
They are not used to mask PEDs, they are used to bring up his testosterone. He was on TRT for many years and has been asked to quit it if he wants to continue getting licensed to fight. Makes perfect sense, receive artificial testosterone due to having low testosterone problems. Asked to quit cold turkey so that he can have a fight in a few months, so he uses something other than TRT to try and maintain some balance of testosterone. It's like giving methadone to a heroin user. His body would be totally wrecked if he didn't take something initially, after being on TRT for several years. Now the reason he was on TRT was probably from steroid use early in his career but it's not like he got popped for performance enhancing drugs.
