I totally agree with Mustang_18 on this one. I think it is a bunch of crap when people say "your body can only use 50G of protein at a time." Where the fuck do people get these numbers.
They hear about it some place, it sticks in their head and then they repeat it. I have a degree in biology and one in biochemistry and I never heard anything like that! I even did my independant research on muscle tissue!
It's the same stupid people that say that red meat take weeks even months before it makes it through the body! BULLSHIT. If that was case I would gain 7 pounds a week. (I eat about a pound a day!)
My point is, don't go throwing numbers around like it is the gospel unless you know what your taking about and have the scientific to back it up.
