I can't speak for Miami but I've been told he was juicing at an early age . SI is loaded w juice so this is really no big deal unfortunately

Regardless that kid had near super human strength , go find manny kids that can close Gip 405 lbs on the bench . He might of been a jerk off but the kid was bona fide tough . Like I said he went toe to toe with another SI heavy weight to a draw lol
