Each serving provides 24 grams of rapidly digesting whey protein with low levels of fat, cholesterol, lactose and other stuff you can do without. There's no doubt this is the standard all other proteins are measured against.
After my GNC protein started to upset my stomach, I thought I'd give the old Optimum Nutrition a try. Yum, amazing flavors (I have mint chocolate right now), still lactose free and BCAAs per scoop! Great for pre and post workout, AND no nausea yet.
