When I studied abroad in the Netherlands protein was equally expensive. I drank a liter of chocolate milk after training. I also ate an enormous amount of chicken.
Think about it, if you get in 5 hearty whole food meals a day with lean protein, complex carbs, veggies, and healthy fat how will you NOT grow?
Evan Centaponi eats pretty much all whole food. Shelby Starnes doesn't do post-workout stuff when he's dieting for a contest because his main goal is to be anti-catabolic. The only powders he has is like a whey/casein mix with some peanut butter and the only reason he eats that over whole food is just out of convenience.
So Food is your alternative for no protein powder.
