What is everyones' take on whey protein as far as health goes. I just bought this Optimum Nutrition 100% Whey Gold Standard™ Delicious Strawberry - OPTIMUM NUTRITION - GNC yesterday (one with the least carbs)

I'm just using it to drink a shake at school and get my grams of protein in, I don't really believe in that "window of opportunity after your workout" bs, I just thought it might be a healthy form of protein for me to substitute some meals with.
