yep, in bodybuilding, the most important thing is not the training so much (you would laugh at how most of these pros workout), not the diet so much (ditto on how they diet), its not even the drugs, or their genetic natural muscularity,
...........its their genetic response to drugs. how effectively do the steroids work for them..............some guys take 5oomgs of test per week, they gain15 lbs (about half of that is water).........other guys take the same amount and blow up 35 lbs
