I'm not calling you a liar so please don't take it that way. I've spoken to Louie on several occasions as well as email and have never heard him say that. What was the context of that conversation. I will agree you can't get to the elite level without it.
I imagine his attitude is that if you're not on drugs you're not dedicated, you're not doing everything you can to be your best. That's the impression I have from rading his stuff.
He also seems to have the same attitude about gear vs. raw, if you're not in gear you're not
"going all out." Really seems to diss the raw lifters. Gear is a joke, almost all powerlifters agree
actually IME, even the ones who compete in gear. When you bench more than you deadlift it's an absolute joke. I think Louie said his athletes were the strongest even raw, but then some PLer, forgot his name, crazy strong dude, put out a challenge, just show up at a meet and prove it. This wasn't long ago.
As far as Ben, only read this last page, but Ben squatting anywhere close to 600 is a joke.
