Gaining size isn t as easy for some as it is for others. For people with faster metabolisms, smaller appetites, and that are constantly on the go, it is difficult to get the added calories and protein needed for muscle growth. That s where Dymatize's Super Mass Gainer comes in. Each serving is packed with 1900 calories, 82 grams of high-quality proteins, and 17 grams of branched-chain amino acids which are directly involved in the building of muscle and speeding recovery. That means that you can put on the muscle and mass you want faster.* Plus, the formula has recently been improved to create a shake that tastes and mixes even better than before. If you re looking for a great tasting way to bulk up, look for Super Mass Gainer.
