Absorbing protein versus absorbing amino acids in a shake is a different comparison. Your digestion does limit nutrient intake, but if you are eating every 2-3 hours and taking digestive enzymes you'll be in good shape. There comes a point though when carbs become more important for growth than protein intake, but that's only when you start pushing 300 pounds. Most people can take 1-1.5 g protein per lb bw, or 2 g in an ideal situation. What it comes down to is the fact that you need to be putting in hard ass work to grow, and if you aren't doing that then the amount of protein you intake doesn't mean shit.
