I think these are reasonable guidelines, considering that an intermediate guy, a typical AAS-using gym rat might be around 90 kg, so 630 mg/w as an upper limit is reasonable. If you can't gain with that, then you need to look at nutrition and training, and after eliminating all negative influences, accept that genetic endowment is lacking. Likewise at the other extreme, a 135 kg super-heavyweight competitor can blast up to 2,700 mg/w (e.g., 850 mg testosterone, 750 mg drostanolone, 600 mg trenbolone, 50 mg/d fluoxymesterone, 50 mg/d oxandrolone). Plenty, on all counts.
