true!

protein before and after is probably the best way to go, unless cutting weight, in which you would only want to have about 1/2 a shake pre and then a low carb high protein shake post. Since I am cutting thats what I am doing, and I am also using ON Monohydrate creatine post workout, I am losing weight and I can actually see an increase in my muscles, granted there is going to be some water retention from the mono, but it is also making my recovery time even less, which is great!
All depends on your goals, so what are they?
