Putting on size requires heavy training combined with a high protein and calorie intake. Where some people build muscle easily, others will burn through nutrition sources rapidly and have a harder time turning their physical efforts into body mass. Perfect for athletes with a fast metabolism or hard gainers who struggle with weight gain, MASS FUSION® contains 950 clean calories per serving of mass-building fuel. Unlike basic gainers, every milkshake-like scoop of MASS FUSION® contains clean carbs like sweet potato and quinoa, time-release proteins, plus the healthy fat MCT – with zero amino spiking! Prepare to shatter your previous size limits and build mass faster than you ever thought was possible.†
