MuscleMaxx is not a well known brand but their three supplements are nothing to shy away from. Mass Gainer is as obvious as it’s title. This protein may be sporting a powerful 1,326 calorie serving but it is made up of all the wrong things. The 56g of protein is a great start, it is the 39g of sugar and 10g of fat that brings the weight gainer down. Something like Real Mass Pro equals the ingredients with 100 calories less. This is one of the mass powders that may get the weight on however not the kind you want.
