He's about 5'2" so I'd say maybe a buck 50.
Wasn't this the guy going around a few years ago saying he had a "Myostatin deficiency" to explain his super-human muscle mass? Oh brother 
No, he's not. He's about 5'10". Somewheres in there.
There is something very strange about his genetics though. Very, very weird look to his physique. He sorta looks like those " myostatin " pics. You know, the ones of the cattle an such ??
