The word is officially out, Chael Sonnen failed the random sanctioned drug test conducted by the Nevada State Athletic Commission (NSAC) that took place in late May for UFC 175. Earlier this evening, Sonnen explained his side of the story in interview on FOX Sports 1, and “absolutely” intends to file an appeal.

Two BANNED substances came back positive in the results: Anastrozole and Clomiphene. Sonnen says these drugs are necessary for his TRT transition and fertility issues:

I have a legitimate medical need for testosterone, I was not an abuser. I was a user of testosterone. So when you come off of this and you have a medical need, you must transition. Now what you’ll take is Clomiphene and HCG. I took Clomiphene and I took HCG. That is what happened. Now this also serves as a fertility drug. That was on accident… I was having fertility issues. That’s not part of my life I wanted to share with you or anybody else. That can be very embarrassing, but now it’s out.
