Mass Gainers

Mass Gainers are used to build muscle mass and size quickly, particularly by ectomorphs or "hard gainers" - those who struggle to put weight on. They are a combination of protein and carbohydrates along with other ingredients unique to each brand and are designed to be taken between meals as a way of boosting calorie intake. The more you eat the bigger you get and mass gainers let you consume more food in a convenient and cheap manner.
