Optimum Nutrition Serious Mass is the ultimate weight gain protein formula that supplies hard gainers and ectomorphs, with the calories needed to pack on pounds of quality muscle and develop a strong, solid and muscular physique. One of Sprint Fit's favourites: this mass gainer delivers nutritional support in the form of 1250 calories, 50 grams of quality blended protein and over 250 grams of carbohydrates in each serve. Add in Creatine Monohydrate and Glutamine into the mix and you have the perfect partner to your intense strength training workouts.
Optimum Nutrition Serious Mass Protein features:
- 1250 calories and 50g of protein helps reach serious weight gain goals
- 50 grams of protein from a combination of faster and slower digesting sources
- Over 250g of carbohydrates to support fueling of intense workouts which aid in the replenishment of glycogen stores - with no added sugar
- Enhanced with creatine and glutamine for muscle growth and recovery
- 25 vitamins and essential minerals including B-vitamins and antioxidants.

As it can be difficult to consume enough calories through regular eating and food, Serious Mass brings quality calories in the form of a tasty shake which can be used in between meals and immediately after your workout. Serious Mass is consumed to help support a calorie surplus for weight gain and muscle building. The added 1g of Creatine Monohydrate has been shown to support muscle strength, power and size when combined with high intensity activities.

Great tasting supplement. I can definitely feel the difference, I don’t put on weight because I have a fast metabolism, using serious mass by optimum nutrition is helping.
