A mass gainer differs from a regular whey protein in that it packs in extra carbohydrates alongside protein to help increase total calorie intake, making it suited to people trying to add weight or bulk rather than simply supplement protein. Whey protein powders like MuscleBlaze Biozyme are lower in carbs and calories, aimed more at muscle recovery than overall weight gain.
