multiply the cycle you would do by 10 and that is more than likely what a top pro does...
but if you look at ronnie coleman right before he turned pro he was all natural! He had like 21" arms and was bigger than most pros are with juice! He was still a cop and there is no way he would have been able to cycle until he quit his job as an officer.
Genetics are a very big part pof the overall package steroids are not a miracle!!!!!!!!
