Steroid testing in baseball

anyone know if these random drug tests they are doing on mlb players are testing for all steroids or just certain ones. just curious on how easy it is for a player to get around this testing.. either way, watch alot of the players stats to drop this season..

in all honesty they shud let the masses have free reign to all AAS's life would be so much easier no?

its' going to be a very boring season that's for sure. Camps are reporting players coming in 15-25pounds under weight. Hmmm...i wonder why?
