  • Provides 50 Grams of Quality Protein
  • Includes a Blend of Fatty Acids and Medium Chain Triglycerides For Energy
  • Great Source of Key Amino Acids

Serious athletes are aware that while trying to achieve muscle mass and strength gains, proper sports nutrition is a must. While striving for such gains, it is essential that you get enough calories, including a balance of quality carbohydrates, protein and fat. Falling short on any of these nutrients can obstruct your performance goals. Pro Performance® Mass XXX™ is the right nutrition drink to help you meet your nutritional needs and keep you fueled while working towards gaining muscle mass and strength.

This special blend of carbohydrates includes 84% complex carbohydrates (maltodextrin and fiber) and only 17% sugar. Each serving of this highly specialized sports formula boasts 66 grams of quality protein and 146 grams of carbohydrates when mixed with 2% milk. It also features a blend of essential fatty acids including some health unsaturated fats, medium chain triglycerides (MCTs) which are quickly absorbed for energy, and no trans fats. This combination of protein, carbs and fat help to provide the extra-calories that you need to put on the added pounds that you want.

Mass XXX supplies key amino acids such as arginine and the Branched Chain Amino Acids (BCAA); isoleucine, leucine and valine. Amino Acids are needed to build the various proteins used in the growth, repair and maintenance of body tissues such as skin, bones and muscle. BCAA helps fuel your skeletal muscles, preserve muscle glycogen stores and help to reduce the amount of protein breakdown. Adding BCAA to your diet can be anti-catabolic and have a protein-sparing effect. Arginine is an essential precursor of nitric oxide and is involved in the body's natural formation of creatine.

In addition, Mass XXX contains a special blend of carbohydrates, the body's primary source of energy. Carbohydrates are an important fuel during intense or high intensity exercise. Carbohydrates also replenish energy stores after high intensity exercise. Furthermore, the combination of dietary protein with carbohydrates following resistance exercise supports muscle protein synthesis.
