alot of these pride guys that used performance enhancers and fought guys twice thier weight are now feeling the effects,when a person is used to training and fighting on enhancers and then cant no more its like night and day,the difference is so dramatic its unbelievable.those enhancers allow the athlete to train twice as often and recover twice as quick,also it increases aggression,makes your joints and ligaments feel better and many other favorable things to a mma athlete.im not saying thats mirkos case but it does seem kinda strange that most of the pride guys are slower,smaller,less muscle mass,weaker,less aggressive then they use to be in pride
