this is what I have seen many important guys and athletes do
in the past they had a "waste" system, a lot of chemistry, a lot of food and a lot of training, but without growing that much (everything they ate and took was only to avoid catabolism from too much training)
by switching to a Top Set / Back Off training, a diet richer in noble proteins, and a reduced training frequency with less chemistry they improved a lot
less chemistry and more results, it seems absurd but it is so, and above all more health
let's stop believing the stories that all the biggest athletes use 5/6 grams, ok the crazy ones are there, but most of them in Off season to grow use a simple combination of
medium/high Testosterone + GH + Insulin + Masteron or Primobolan
