A completely ignorant statement.
As an adult, and with lousy genetics, I gained 30 pounds of muscle at 9% BF in 2 years. COMPLETELY DRUG FREE.
I worked out at a gym in the 80's where nobody there ever saw a steroid. Many of those guys looked better than most of the guys posting pics on this board.
Guys like Larry Scott, Dave Draper, Sergio Oliva , Don Howorth and yes Arnold, took dosages that were a fraction of what I see recommened for first timers. No one wants to accept that because they'd then have to admit they haven't got the guts,genetics, and work ethic necessary to look that good.
Sure lots of supps are crap. I've said so myself. And most supplement manufacturers are just salesman. But when you have experts like Anthony or someone like myself who's been doing this for almost 40 years designing stuff with the bodybuilder in mind and they've been show to improve muscle growth, even a litte, well, f*ck dude, a lot of people want that little bit of an advantage and will take it. If you don't, you don't have to.
Guys like you need to step back from the keyboard more and get a little closer to the weight rack.
