does he take deca and glutamine for recover?

That actually depends on his work life and how much cardio he does with this workout. So there is a good chance that he does need that amount of calories.

I agree with carrnage23, this is just propaganda to sell their products...

that would be true if this workout was the only thing he was doing but realistically he is obviously going a lot harder and I do think most of his carbs/protein are being utilized because hes a body builder this isn't a body builder routine its just a mass gain he obviously does way more stuff that he doesn't mention here to keep things straight forward

He is a professional body builder and prob hits the gym two to three times per day. I guarantee he does eat all of that food. I eat 3500 cal/day and I have a very structured workout plan that is working right now but I know that if I stop eating so much I will lose weight. I would eat more but I don't make all that much money to spend half of my check on food.
