After his heavyweight fight of the year, Bigfoot failed his post fight drug test for elevated testosterone. This, despite having been granted an exemption for TRT.
MMA Junkie first broke the story:
Silva is on a medically approved regimen of testosterone replacement therapy (TRT), and had been in compliance with therapeutic guidelines on all pre-fight tests performed prior to the event,” a statement issued by a UFC rep read. “The results of his test on the day of the event indicated a level of testosterone outside of allowable limit. Silva has been informed that the elevated testosterone level is a violation of the UFC Fighter Conduct Policy and his Promotional Agreement with Zuffa.
After the news was released of the positive test results Bigfoot responded on Facebook with proof that it was not his fault.
Clarification: Months before my fight I looked for the UFC doctor Marcio Tannure in Brazil so I could start the hormonal replacement “TRT” which was authorized and recognized by a professional. I started the treatment and 2 weeks before my fight I did all the exams required by the UFC. My testosterone level continued to be low so I was recommended by the doctor to increase the dosage. Unfortunately my level increased too much and caused me to suspend. I only did what was recommended by someone trained who understands about the subject therefore it was not my mistake. I’m cool because I know that the mistake was not made by me,I never tried doing anything wrong for my fight.
