ON Optimum Nutrition Serious Mass Protein 101: Winter is coming...or Bulking Season. When it's time to bulk, it's time to add mass the right way. The way you build muscle mass is to overload the body with the proper nutrients that force the body to build muscle faster. Serious Mass by Optimum will contain the right carbs, protein, and calories to do this. 

Mass Gainers are also great for anyone having difficulty putting on size due to their fast metabolism. Serious Mass will load your body with enough nutrients post-workout that will prevent it from breaking down existing tissue. This will allow your body to put on mass compared to a whey protein shake.

Why This Mass Gainer is Great: Serious Mass is the ultimate in weight gaining formulas. With 1,250 calories per serving and 50 grams of protein for muscle recovery, this instantized

(not clumpy) powder makes the ideal post-workout and between meals shake for sizing up your goals. Serious Mass provides you with the tools you need to pack on the pounds and help you develop the physique you’ve always wanted.
