ON Serious Mass also contains 250g of carbs, which is the second most important macronutrient for building muscle, right behind protein.

When you combine that with the fact that this product also contains 250g of carbs, 50g of protein, and 1,250 calories per serving, then you are ingesting a monster of a weight gainer.
Along with the effects of Creatine, ON Serious Mass also is enhanced with Glutamine & Glutamic Acid. These both help in the formation of protein in the body, which is used to help build muscle.
