Here are my 2 cents worth from a thread at CEM:
I think this is a topic that could be argued indefinitely. Most of the experts say protein requirements are in this range for strength athletes:
"Present data indicate that strength athletes should consume approximately 12-15% of their daily total energy intake as protein, or about 1.5-2.0 g protein/kg.d-1 (approximately 188-250% of the U.S. recommended dietary allowance). Although routinely consumed by many strength athletes, higher protein intakes have not been shown to be consistently effective and may even be associated with some health risks." (1)
I get around 200 grams a day and do OK. The question always arises whether you need more on steroids. I don't know. One could make a case either way.
For instance, amino acid flux studies of people using steroids generally show lower rates of amino acids leaving cells, suggesting that the cells are recycling their proteins for muscle rebuilding more efficiently when a person is using steroids:
"We recently reported that 5 days of oxandrolone administration increased skeletal muscle anabolism by stimulation of protein synthesis, because protein breakdown was unchanged (15). Also, we reported a significant decrease in outward amino acid transport (FV,M), along with a calculated increase in protein synthetic efficiency, together indicating increased intracellular reutilization of amino acid"
This would argue for lower protein intake while juicing.

Torsten, an MD at our site has presented compelling studies showing that a high protein diet actually leads to a catabolic state by inducing low grade metabolic acidosis. (Amino acids are acidic, after all.) The acidosis elevates cortisol levels leading to muscle catabolism. The low pH degrades bones, and the calcium is deposited as kidney stones. Unless a person undertakes a serious buffering regimen (potassium citrate is best according to studies presented by Dr. Torsten) the acidosis will be a serious impediment to gains.
