I had the opportunity to become close w/ a couple of top level national competitors at the gym I had been working out at for the past year, prior to just moving out of the country. They advised that most top level amateurs and the pros do lie about what they take, especially if they consider you legitimate competition. They don´t want to give up their secrets and their edge. Since I was not a competetive threat, over time, I got some truthful answers, and what it really boils down to is that it varies per individual. One guy I talked to was running 750 mg test, 400 deca and 3 i.u. of growth, but he admitted that that is a cruising dose for most guys. Another guy I talked to was running 4,000 mg of test, 150 of anavar (a day) and 20 i.u. of growth/day. He knew of many guys taking up to 5,000 mg of test. Insulin is extremely popular and what A lot of guys attribute to blowing them up to much bigger sizes. One guy said why would I want to take 750 mg of test? That´s just enough to shut me down and replace what I lost? He said even if you´re only eating three times a day, when you´re at 4,000 mg plus of test, you will grow. Another thing I found interesting is that they did not train to consistent failure for fear of overtraining and frying the central nervous system. Instead the would do high volume, moderate intensity, just to get the blood flowing and circulate all their nutrient and super supplements to the muscle tissue.
For the record, non of this is my opinion or advice or what I do. It´s just what I was told by some guys much further up on the bodybuilding food chain and the scale.
