I've wondered the same thing for a while now. Hopefully someone will know. Is it just me or did he look alot smaller in Pitch Black the in his newer movies?
After looking at his build for awhile in Chronicles of Riddick I think he is natural. He doesn't look like a bloated gorilla. I see juice monkies all the time in the club I work at and they all look the same.
Looks natural to me. His abs etc arn't that defined in "XxX", he doesnt look ripped and mega veiny at all.
If anything he could have better ABS, but pretty good physique tbh.
