Mass Attack Heavyweight is a High Protein and Carbohydrate food supplement with natural colourings, natural flavourings & artificial and natural sweeteners. It is a high-calorie version of the ever popular Mass Attack family. Some people have a very fast metabolism, which means it is physically very difficult to eat enough without feeling sick or bloated in order to gain weight. Mass Attack Heavyweight is specifically designed for "hardgainers". Containing a massive 60g of muscle-building protein, together with quality complex carbohydrates and medium chain triglycerides (a fat that is processed in the body like a carbohydrate). Mass Attack Heavyweight packs a monster 1300 calories per serving when mixed with water (more if mixed with milk). This potent blend of nutrients and energy should be enough to pack muscle on the most stubborn frame. In addition, Mass Attack Heavyweight contains the heavyweight gain stack, a precise mix of Creatine monohydrate and dextrose monohydrate designed to transport Creatine to the muscles quickly and efficiently. Continued supplementation with Creatine has been shown to increase muscular performance in repeated intense exercise bouts like weight lifting. Unlike most high calorie mass gain products, Mass Attack Heavyweight mixes easily in a shaker and is not overly thick, making it easy to consume. Available in delicious flavours, Mass Attack Heavyweight contains no artificial colours, flavours or preservatives and is unique in that it also does not contain any artificial sweeteners.
