Optimum Nutrition Serious Mass


Optimum Nutrition Serious Mass is designed for the “hard gainer”, those who just can’t put on weight or keep on weight, the skinny guy with a fast metabolism. Sound familiar, don’t despair the calorie dense Serious Mass will have you gaining lean muscle before you know it.


ON Serious Mass provides 1,640 calories when consumed with low fat milk making ramping up your calorie intake easier and more convenient. Serious Mass contains 50g protein per serve from fast acting to slow release sources allowing for a rapid and prolonged release of amino acids into the circulation to repair muscle. Combined with a massive 252g carbs to fuel muscles, restore glycogen levels and enhance nutrient delivery, Serious Mass should have you stacking on muscle mass. Also containing anti-catabolic nutrients such as glutamine and creatine, proven to increase lean muscle gains, struggling to gain weight should be a thing of the past.



Whether you’re a novice or professional, Serious Mass will get you to your goal weight faster and with noticeable strength gains along the way.



Optimum Nutrition Serious Mass Directions:

Add 2 heaped scoops of Serious Mass with 700ml water or low or non fat milk  and consume 30 - 45 minutes post-workout. 

New users may begin with half a serving and increase gradually one or more full servings per day.

For best results use Serious Mass combined with intense weight training (3 - 5 times per week).
