I met Kurt back in 2000 at Gold's Gym and he was definitely a good sized guy, same type of physique as Benoit. But over time you could see it go down hill. He had pinched nerves in his neck and back which limited his lifting abilites.
Did he do GH, probably since there is no way to test for it.......
At the rate he IS going, he will be in wheelchair in the next 5-10 yrs, just like Dynamite Kid....
