A testosterone user, himself, UFC commentator Joe Rogan can't seem to account for Vitor Belfort's vicious performance last weekend in Sao Paulo, Brazil.

Belfort passed four different random drug screenings conducted by USADA leading up to his Nov. 7 TKO win over Dan Henderson, but Rogan isn't quite ready to give 'The Phenom' the benefit of the doubt.

"When you look at Vitor now, he definitely looks better in this fight then he did in the Chris Weidman fight," Rogan said on his podcast. "He looked more built, but he still didn't look like he did when he was on [testosterone replacement therapy] TRT. But the question is, what is he doing now? If he needed testosterone replacement before how has his body recovered like this? Has he figured out some nutritional way to get around it or is he figuring out some undetectable way to use? No one knows. We're not going to know unless he gets caught.

"Tim Kennedy said it best. He said, 'It doesn't look like Vitor is using as many steroids. Tim Kennedy is hilarious. He said he wanted to fight 'the slower, fatter Vitor.'"

Bookended by title bouts with former champion Anderson Silva and current champ Chris Weidman, the era of "TRT Vitor" only lasted from 2011 to 2013.

Belfort was awarded a testosterone use exemption (TUE) following his first-round KO loss to Silva at UFC 126 and made his return without the TUE in his TKO loss to Weidman at UFC 187.

We know Belfort's record against the champs without TRT, but Rogan believes those title bouts may have gone differently with testosterone involved.

"I think Vitor on TRT is one of the scariest fighters the MMA world has ever seen," said Rogan. "At the highest level. I would have loved to see TRT Vitor vs. Chris Weidman. TRT Vitor vs. Anderson Silva. I would have loved to see it. I understand that it's not fair and I wouldn't expect Weidman to take that fight if he knew Vitor was on TRT. I wouldn't expect it, but damn, I would have loved to see it.

"He knocked out Michael Bisping with a head kick and f***ed his eye up, permanently. Michael Bisping's eye is permanently disfigured because of Vitor kicking him in the head. He's one of the scariest guys in the history of the sport when he was on TRT. It was like a four-fight run where he was just f***ing smashing people."

Squats.

Definitely the most weight I've done using such a narrow stance, also went down lower than usual on the low box. Altogether with bar and plates 425lbs #GATathlete GAT Posted by Jon "Bones" Jones on Thursday, November 12, 2015

No funky.

My garbage opponent missed weight! He's on the clock. — Ben Askren (@Benaskren) November 12, 2015

Santos missed. My demand is that Santos makes 190lbs tomorrow or else the fight is off. — Ben Askren (@Benaskren) November 12, 2015

So sick of amateur Jabronis that refuse to honor the contract put in front of them. — Ben Askren (@Benaskren) November 12, 2015

@Benaskren is a true #champion!!! Came ready to fight. Gave Santos another chance and Santos still can't make weight!! #unreal #ONE — Loren (@lorenonefc) November 13, 2015

I'm disgusted. Sapo fails to make weight then despite Askren offering a fight at 190lbs, Sapo still refuses. Completely unprofessional #ONE — Victor Cui (@victoronefc) November 13, 2015
