First of: I agree that the claim about Berdych's legs is indeed just a step to far. Big muscles can be perfectly natural.Kokoso said:So explain it to me please. Thanks.
But your notion that Ped's would give an even growth on all his muscles is wrong (at least you seem to claim that, sorry if I misunderstand).
Muscles need training. If I take Steroids and only train my arms, my arms will grow stronger, the rest of my body not so much. Also, some natural abilities etc. will come into play (not everyone responds the same). So if Berdych has natural big legs, it's not a given that they would even grow bigger if he uses steroids. It depends on his training regime, his response etc.
