So with that the latest fighter to be approved for a therapeutic use exemption (TUE) for testosterone replacement therapy (TRT) was former UFC heavyweight champion Frank Mir prior to his fight at UFC 146 against Junior Dos Santos.
Nevada State Athletic Commission Executive Director Keith Kizer confirmed the approval to MMAWeekly.com on Friday.
The TUE allows a fighter to receive treatment from their physician for low testosterone, but they must still test multiple times prior to and after a fight for ultimate approval.
Mir underwent all the necessary testing required by the commission and his testosterone levels all fell in line to compete on the card.
Ultimately, Mir lost in the fight as he was finished by Dos Santos with punches in the 2nd round.
TRT has become a highly publicized issue lately in mixed martial arts with more and more fighters coming out as practitioners of the process as prescribed by their doctors.
Recently, UFC 148 main event fighter Chael Sonnen had his application for a TUE for the same TRT treatment approved by the Nevada State Athletic Commission for his bout against Anderson Silva on July 7.
