50 grams protein per serving. 100 % whey protein isolate. 10,900 mg BCAA's per serving. Lactose free. 4.6g l-glutamine per serving. 600 calories. Instanized. We're all more than muscle. Lean mean carb free machines. 50 grams of 100% pure whey protein isolate and not a carb in sight. And it still comes with glutamine and nutrients, but no lactose or impurities, so it's easy to drink. Your gut will agree.
