Excellent points.
Just pointing out that for most, drugs, no matter how much, isn't going to take you to pro size as far as lean muscle mass. I've just known too many people over the decades that juice to the extreme (10grams/week) plus gh/slin that just didn't get there. They got very big and heavy but fat. And they were using the same gear as others who did much better on less.
I agree, true
Genetics is the most important attribute, that’s a given, combine with powerful PED’s and you have an exceptional physique
Seems flex and Kevin were examples of tiny individuals when truly natural, skinny, but very lean, hard gainers but combined with anabolics they blew up. The downside to their physiques from observations is that they are more quicker to lose A LOT when coming down dosages or stopping as say compared to someone like Shawn Ray or Ronnie whom are built much different and more of that thicker, bigger boned meso frame than the other two
