His statements do make me curious as to how many fighters do take TRTs.
What are the chances that Anderson Silva does?
It's unlikely Anderson does. It's exceptionally hard to prove someone isn't doing something, but if he is taking testosterone, it hasn't been approved by a state AC.
The last state Anderson fought in was Nevada. In Nevada, they've only given out three (one more than USADA has ever given out) therapeutic use exemptions (TUEs) for testosterone. The recipients were Dan Henderson, Todd Duffee, and Shane Roller.
Here's a list of fighters who have been on TRT according to athletic commissions, published reports, or self admitted:
Chael Sonnen- Pretty famous case. Said he'd keep using it, so he may have gotten TUEs from Texas and Illinois. Both those commissions are bottom of the barrel.
Dan Henderson- Definitely has a TUE in Nevada and has since his Pride fight with Wanderlei. Interestingly, to me anyway, he was approved years before the NSAC implemented a rule that you couldn't qualify for a TUE for TRT if Anabolic steroid induced hypogonadism was the reason you needed TRT, or if you had ever done steroids at all.
Todd Duffee- Definitely has a TUE in Nevada.
Shane Roller- Definitely has a TUE in Nevada.
Nate Marquardt- Was on TRT for at least his fight with Dan Miller, but ultimately was denied his TUE in New Jersey and not allowed to fight in Pennsylvania. Has failed a steroid test in the past.
Dennis Hallman- Was diagnosed with celiac disease in the last few years. Making him the only person on this list with a diagnosed disease that can cause hypogonadism. I think he's been on TRT for his last four fights, meaning he has TUEs from California and several other ACs. But he's also been busted for steroids before, so there's that.
Bristol Marunde- According to Dave Meltzer, Marunde had a TUE for TRT in Ohio when he fought Jacare.
There could be more. I'm sure there are in rinky dink ACs.
But Nevada has been public that they've only issued three. Back in 2010, California had issued a total of one, but is probably up to at least two now that Henderson and Hallman fought there recently. The NJAC wouldn't give names to a reporter but said they've given out less than five. I haven't seen the Ohio AC make any statements about it. Those are the closest things we have to good commissions, though even they aren't what I would objectively call good. But compared to most other state ACs though, they're great.
