Steroids in MMA
Which MMA Fighter Will Test Positive For Steroids Next?

Vinicius Quieroz Fired by the UFC After Testing Positive for Steroids

Just a month and a half after Chael Sonnen tested positive for performance enhancing drugs following his middleweight title fight against Anderson Silva, the UFC has more dirty urine on its hands. MMA Junkie broke the news yesterday that Octagon first-timer Vinicius Quieroz — who was submitted by Rob Broughton in his debut at UFC 120 in London — tested positive for the anabolic steroid Stanozolol after the match and has been fired by the UFC.

As they usually do for overseas events, the UFC conducted its own drug screening at #120, testing main event fighters Michael Bisping and Yoshihiro Akiyama, as well as six other fighters selected at random. Quieroz was the only fighter who tested positive. In addition to his release from the promotion, the 5-2 Chute Boxe product will forfeit an undisclosed discretionary bonus from the UFC; his test results will also be given to the Nevada State Athletic Commission, which could affect Quieroz’s ability to get licensed to fight in the U.S.

As the newly-updated MMA Steroid Bust Timeline tells us, Stanozolol has been the PED of choice for fighters such as Tim Sylvia, Kimo Leopoldo, Phil Baroni, Ken Shamrock, and Chris Leben — who was also nabbed by the UFC’s independent testing at a U.K. event two years ago.

According to MMA fighters who have seen it first-hand, anywhere from 50% of competitors to everybody except Nate Diaz turn to drugs for athletic advantages — and having another steroid bust in the UFC so soon after the last one only underscores that it’s a serious problem. It also proves that not all steroid busts are created equal in the UFC. If you’re a prospect without a fan-base who loses his first fight in the prelims, you’re clearly expendable. (Later, Vinicius.) But if you’re a title contender who knows how to promote a fight, well…"what else do you do to a human being?"

Sonnen is going to be vindicated! You guys just wait! He was on Testosterone and it's going to come out in his hearing that those hormones were medically prescribed to help him through the last stages of his sexual differentiation procedure. Who wants to go through life as a non-functioning sexual hermaphrodite? It's like a virtual train wreck of biology and naughty parts.

Actually, I think some of the anti-UFC crowd should take away from this that the UFC is actually doing testing at their own expense when/where they aren't required to. Is it perfect? Hell no. But that is being more responsible than a lot of organizations would be. I don't love everything they do, but I gotta give them credit where it is due.

I'm totally with ArmFarmer on this. It makes perfect sense to ditch this loser.

Plus, if this guy ever moved up the ranks and had to fight Lesnar, Brock would pronounce his name "Queer-Ozz", and that just doesn't sound good on camera.

Whoa! It's Danny Glover!!!

If I had the choice on who to fire, I'd fire the guy who I'd get more pleasure out of firing.

Therefore I'd fire Sonnen. Even if he wins the appeal. Fuck that guy.

Sonnen tested positive for high Testosterone/Estrogen ratio, which is indicative of anabolic steroid use. This guy tested positive for stanozolol, a known steroid.

There is a difference... but really, not a big difference. Fuck PEDs.

I just want to know what it is Sonnen took. I mean, he TOLD the fuckers he took it and that he'd prolly piss hot. Then he tries to appeal?

I don't get it.

Guy looks like a cross between James Thompson and Lius Cain.

@V_N - sonnen has already lost his immediate rematch for the belt and has had his name linked to that failed test for 3+months too. even if the commission decides to reduce the sentence, that will not "prove his innoncence". consider sherk; everybody still thinks he cheated.

If Sonnen wins his drug trial, will that really prove his innocence? Or just how good his verbal techniques are?
ArmFarmer- November 3, 2010 at 7:59 am
Makes sense to me. If I ran ufc I'd treat some noob that got finished in his debut by some other noob a lot differently than my contenders and title holders too.. fact of the matter is, this guy won't be missed. I wouldn't even know who he was if he hadn't popped positive.

Also, Nate Diaz is in fact on performance enhancing drugs, just like his brother. According to the guy that ruled the diaz/gomi fight a no contest anyway...

Hey, it's Chandella.

If you're Leben or Sonnen, you apparently deserve a second chance. If you're nobody, GTFO fucker.

hehe - cp is not trying to get on dana's good side

Let that be a lesson to all you kids out there. If you're gonna cheat to win, make sure you win.

An what of Sonnen's fate?

And what's this I hear about a sack of dead babies?

Said Vinicius: "In hindsight, I probably shouldn't have drank Sonnen's pee."
