Recently I've gone back to using the cheaper whey proteins instead of the more expensive brands. Frankly I don't see too much difference between them, and the price difference is hard to ignore nowadays...
I just use two scoops of this stuff and I get just as much protein as FOUR scoops of Cytogainer or Muscle Milk. Granted, it tastes like shit, but mixed with milk and banana it all tastes the same.
A 3 pounder of the cheap stuff lasts me almost as long as a six pounder of more expensive brands, and leaves me more money for actual food.
Anyone else do this, or is there a compelling reason to use the most expensive whey protein?
