Everyone will believe what they want to believe. I would guess that most pros run quite a bit more than is mentioned here, but I also know there is a wide spectrum of response, and assuming things tends to backfire. When I competed, I usually ran more than Dusty mentions here, and I'm like half his size. My typical test dose was about 1.2g per week and I never competed at more than 202 pounds. I tried 2g test for a short period but noticed zero difference (maybe because my genetics suck) so I stopped. I also rarely cruised, at least for the first handful of years I competed. And I was a shitty pro. I made a lot of progress from my starting point, though. I probably could have done it with less, but there was no control condition in the experiment so who knows. Later in my competitive career I started using a little less, and got away with it for a little while, but over time my physique suffered (but at the same time I was also getting older, which also plays a role).
I'm not going to sit here and say that the top pros don't use a lot - I'm sure many / most do. Most reading this already have their minds made up about this stuff, and aren't going to change (their identity is tied up in their belief).
Perhaps like you say I'm not someone that can be trusted, but I know that I'm human, which means that I only see a tiny fraction of what is going on in the world, and that tiny fraction is biased regardless of my awareness of it (and the same goes for every human reading this). So I try to be a bit slow(er) to judge, or call bullshit, when I'm really only guessing at best.
