Clearly you know nothing of Clancy Ross or any of the old guys.  You need to do some more research in regards to when Steroids were first implemented.
Now it's the word "implemented?" Just like you apparently flip-flopped on the Tom Prince bet, you've now changed from when something was invented to when something was implemented. 
And, clearly, because I state that when a drug is invented, I have no idea about older bbers? Good generalization! 

 Just like your other generalization that "no drugs were used PERIOD." 
You weren't there, you do not know if they used or not. You can't say that. But the fact that the drug was discovered and invented means it 
was available to them and they COULD have used it.

Lo and behold it starts in the same year that Ross' did (According to your background check anyway), and years after testosterone was discovered. 
You just cannot make the assumption that your correct and say they never used. 
There's a story from MMI years back, where Vince Gironda, Bill Pearl, and numerous others were sitting around a table discussing wether to up their dosage from (I think it was) 5mg to 10mg. Nobody knew the effects it could have, but that they were getting good results so they all wanted to try to use more. 
As far as Ross' workout routine, did you ever read the article regarding him in MMI about how he can't move anymore due to his joints being so fucked? He attributes this to his workout routine, saying how he used to do the same workout 3x/week and always heavy and hard. Now he regrets that, saying he'd changed it up. Just a FYI...nothing more.
