Ripped Up Nutrition Lean Muscle Gainer is a high protein high-calorie supplement to support lean muscle gains. The carbs to protein ratio of 2:1 ensure both more protein per serving and sufficient energy to meet heavy duty work outs. 30g of protein per serving from a combination of Whey Protein Isolate & Whey Protein Blend ensure quick recovery post work out. Zero added sugar in the supplement and added Creatine and Glutamine makes it the best solution for lean muscle gains.
