500 grams of protein is totally unnecessary. I bet if he got less protein and more carbs at the same calories he would have got the same results.
If he ate 500 grams of protein on a regular basis, I seriously questioning what kind of nutritional theory he's basing that on.
CT's quite an athlete, wonder if he was able to regain any of the strength after he took the pictures. The 230 lbs was obviously a few pounds on the heavy side, my guess he would've been lifting just as good at around 215 lbs, or just under.
