Looking
to bulk up? Or do you have trouble getting the calories needed to support lean
muscle growth? Mass gainers differ from normal protein powders
as they contain more carbohydrates and high-quality calories per serving. It’s
hard to cram enough protein, carbs, and calories into each day to fuel your
body’s bulking needs. Mass gainers are a convenient, high-quality way to get
the fuel to build the body you want.
