I need a good post-workout drink but I can't afford Surge. I'm 16 and I can pretty much have only 2 out of these things: a car, insurance for car, and gas. So I am on kind of a tight budget. I'm taking protein and creatine right now and was wondering what would be a good post-workout drink b/c usually all I take is my creatine. Also if anyone knows a good place to buy supplememtns in bulk please include it in your post.
