Ross and I butt head a lot, but when he's right, he's right.
I know it's hard for people to accept, but pros aren't pros because they take more gear than everyone else. They're pros because they have ungodly genetics AND a great reaction to gear.
Could they be exaggerating and maybe forgetting a little this or that? Sure. But I've seen guys blow up on a few dbol a day and I've seen guys take over 2 grams a week and they looked no better than when they took 750.
So yeah, I believe it. Look at Dorian after one year of training. The progress was ridiculous. THe guy just had those one in a million genetics.
