The other thing that is misleading here are the sports who have athletes using the juice, substantial psychological effects themselves. The science is there on the harmful effects of these substances, however know one wants to discuss them. Look at the high profile football players from the 70's, 80's and 90's that have suffered tragic ends, they were all notorious users, same with guys like Lenny Dykstra.
Don't forget baseball.
In college I worked out in a couple of hard core gyms.
There was always the "clean" side and "juice" side.
It was easy to tell when a guy started to "juice".
All of a sudden his bench would start going up in leaps and bounds.
We used to laugh when they'd say it was a new diet.
Now I work out at Gold's.
You hear guys talking about the "benefits" of juicing,if you do it "right".
"Right" meaning you don't get caught.
When someone brings up the harm they cause the usual answer is something like "I'll deal with that when I'm 40".
