In order to gain muscle mass you need to increase calorie intake, especially calories from protein. A daily serving of ANABOLIC HUGE contains a massive 45g of protein (Whey Protein concentrate, Soy Protein Isolate, Calcium Caseinate), complex carbohydrates (Maltodextrin and Waxy Maize Starch) and is very low in fat. The inclusion of MEGABOL MATRIX (Glutamine, Creatine monohydrate, Taurine, Leucine, Iso-Leucine, Valine) will ensure that you remain in an anabolic state, which will allow you to pack on huge amounts of muscle mass faster than ever before.
