Goodmorrow,
I have all the old late 70's mags that Pete talks about this. I believe it was Rochester NY..the city made famous by GetBig's own Bob Chick! I also have a mag where the guys were talking about what Arnold took...they did the same thing and didn't look like Arnold. I've witnessed Pro's in my very own house inject bottles of Steris Test Suspension into many bodyparts two days before the contest. Many people feel they need to lower the dossage when talking because it discounts all the hard work they've put in. I can tell you that the Pro's in the late 80's and early 90's did at least 10 grams, at least the Pro's that I knew. Now injecting two 20cc bottles of Steris test suspension at 100mgs a CC might have been "panic" mode, but I don't think so.
On the upside I have always maintained that one can achieve a Pro Bodybuilding Physique just by proper nutrient timing,working out and getting enough rest. These are three things that are a must in achieving a Pro Build. If one of the componets is off then one will fall short.
STAY POSITIVE!!!!!!!!!!!!!!!!!
