This is the ultimate new, re-formulated lean muscle gainer you've been waiting for! Mutant Mass is a serious calorie-dense formula, designed with only hard working athletes in mind, who demand power, absolute size and all out strength. If you are serious about gaining slabs of lean muscle mass, faster than ever, then Mutant Mass is the answer. Mutant Mass was developed following several years of research and is based on sound, proven science. More importantly though, the finished Mutant Mass formula was also tested in the gym, where it was put through its paces by real life bodybuilders and strength athletes. Mutant Mass is all about gaining rock hard muscle - and lots of it! Building muscle requires the right protein mix to expand the muscle tissue and repair it fast. The protein must also be spared from being wasted for the body's energy needs, while the muscle also requires massive infusions of clean calories to replace glycogen used up during training. Digestion, absorption, triggering calorie uptake and manipulating protein sequencing - the Mutant Mass formula takes all that into account and hits a home run like nothing else you've ever tried! With every conceivable form of the highest-quality proteins available, healthy "fat burning" fats and low GI, slow-burning carbs and gut healthy fibres, this is truly the most thoughtfully-designed lean mass gainer formula in the history of bodybuilding!
