Chris Weidman: Vitor Belfort using testosterone after he got caught cheating is 'unfair'

If the decision was up to Chris Weidman, then Vitor Belfort would be retired.

So too, would Chael Sonnen, Frank Mir and countless other mixed martial arts (MMA) fighters who are currently relying on testosterone replacement therapy (TRT) to help them stay competitive in combat sports.

Even if they are doing it within the established guidelines set forth by participating athletic commissions.

The reigning UFC middleweight champion is expected to defend his 185-pound strap against "The Phenom" later this year in Las Vegas, Nevada, and just like Michael Bisping and Luke Rockhold before him, is not overlooking the fact that Belfort has been a bad boy in previous "Sin City" outings.

His comments to FOX Sports (via MMA Fighting):

"He's failed a drug test before. He's on TRT now. I don't agree with TRT to begin with, so him failing a drug test and being on TRT, I don't really like it. So I appreciate there will be a commission making sure he's doing things right. I don't have high testosterone at all. I'm completely fine. I guarantee his testosterone on TRT is two or three times higher than mine. I wake up and I work hard two or three times a day. I don't feel that there's a need for it, and if it comes to point where you need it, then you retire, you don't fight. Fighting is a sport where strength is important, and if you're going to have extra testosterone, especially after you've been caught cheating, it's unfair."

Despite what UFC President Dana White says, Weidman may have an unlikely ally at the Nevada State Athletic Commission (NSAC).

Belfort tested positive for 4-hydroxytestosterone following his unanimous decision loss to Dan Henderson at PRIDE 32 way back in 2006, when the Japanese-based fight promotion made its way to Las Vegas. He was suspended for nine months and fined $10,000 for the infraction.

Fast-forward six years and Belfort is now competing on TRT.

Not coincidentally, he's performed better than ever, winning his last three fights by way of devastating head-kick knockout. That list of victims includes the aforementioned Bisping and Rockhold, as well as "Hendo," a fellow TRT user.

"The Phenom" claims he's been relegated to events in Brazil because of his marketability and not because he's ducking stateside commissions, and even promises to abandon his testosterone treatments (if he has to) for a return to Las Vegas, though feels such a move would put him at a competitive disadvantage.

Now he knows how Weidman feels.
