Nobody on this site knows whether Jason is juiced or not. Juice is a short cut, & if Jason is doing everything else right, he wouldn't necessarily need it to compete at top levels. For decades, baseball players did quite well without it. & Jason didn't get all his strength & stamina from a bottle, nor did Barry or Mark or Sammy.
As for Grimsley, his baseball career is over. & he's stopped talking to the feds. So far no elite athlete in the general sports arena has gone to jail for anabolic use. If Grimsley had been a competitive bodybuilder, he'd already be behind bars.
