Valentijn Overeem doesn't know why his brother, Alistair Overeem (36-11 MMA, 1-0 UFC), tested positive for elevated levels of testosterone prior a fight against champ Junior Dos Santos.
But he said it would be news to him if Alistair needed the hormone for medical reasons, as recent speculation would indicate.
"Because I know him so well that I think I should be aware of something like that," Valentijn Overeem today told MMAjunkie.com (www.mmajunkie.com). "If that was the case, I think I would know. I would be surprised."
Valentijn Overeem, a longtime MMA fighter and former Strikeforce fighter, is in Holland with an expectant girlfriend and said he hasn't trained with his younger brother since he left for the U.S. in March but said he never received any indication that Alistair was suffering from a condition that would necessitate the use of testosterone. He is unsure why the pre-fight drug test came back high for a high T/E ratio.
"There are different reasons why someone could have high testosterone," Valentijn Overeem said. "Taking steroids is one of them. Some people have natural testosterone at a high level anyway. I'm not saying my brother is one of those people, but there's more possibilities. If the [athletic commission] tests the sample again, just to make sure there were no mistakes, I think that would be a good start." LINK
