400 to 600 grams. Yes. You disagree? Stay small then. I don't care.
Who says he can only eat 6 times a day? Who says he can't eat ten times a day?
Your only limiting factor is you.
I also think we shouldn't be dishing out steroid advice to someone we know nothing about. We don't know any stats about the OP, his age, time training, weight, height, what his goals are, etc. We know nothing about his diet or training, yet someone is already telling him to use test prop...oh and look, he knows NOTHING about that either!
He says he "will have a good diet and workout routine while taking steroids". I am saying if you don't ALREADY have a good diet and workout routine that you've already been doing consistently for at least 2-5 years (depending widely on the individual) then you're NOT READY for steroids.
How much are you trying to gain in how short of a time? You just trying to get a "beach body" for summer (good pumped look and not too much bloating)? Steroids CAN (sometimes-not always) help someone with a shitty diet and poor training routine look better while he's on them. But, if you don't already have your shit together like I am saying, it won't fuckin matter and you may as well save your money.
600 grams of protein a day is rediculous. You would have to relay on supplements for the majority of that. I take in 300 and thats a hell of alot of meat....600 would be VERY hard to keep up, exp if you try to eat same everyday. Your kidneys would'nt let you do that for too long anyway!
