IF u want
whey protein, is best to shop by price. IF you workout, u need 1 lb per body weight daily (all of it shouldn't come from supplements). IT dont matter which brand protein you take. I usually go with On's
Optimum Whey because of the price and you get 24 grams of protein per serving. The reason why they sell protein for cheap price is beacuse they produce there own, and i have never once seen on's optimum whey protein advertise in physical magazine. Nitro-Tech probably dont produce there own protein and they advertise like crazy in workout magazines.
