Lyoto Machida Accepts Blame, Apologizes for UFC on FOX 19 Anti-Doping Violation
A few short hours after it became public that he admitted to using a banned substance in a routine out-of-competition drug test, Lyoto Machida took to his Facebook page to explain the situation, and to apologize.
“I'm here to tell you that I was caught by surprise by this news. It has been very dificult for me,” Machida wrote on Facebook. “I've trained a lot for this fight, I've dedicated a lot with all my team mates. I want to tell you that I really didn't know about this substance, so I listed it on my declaration form amongst everything else I was taking, and this substance was recently banned in 2016, so I take the blame for not knowing that, and I'd like to say I'm really sorry and apologize to my fans, team mates, and my family… I always try to play by the book, but unfortunately this happened.
“The supplement used by Lyoto was 7-Keto, that contains the substance DHEA, found in products sold at every supplement store and it's very popular.”
