Gaining muscle is often said to be 20% training and 80% eating, yet most people mess up the eating and get less results than they could have. Part of the reason for this is the large amount of calories needed to gain muscle; calories which have to come from good food sources. If you don’t have the time to prepare these meals (6-8 a day) and don’t have the appetite to consume them, don’t fall off by skipping meals or shoveling junk down your throat. Get wise: Get a healthy weight gainer such as Optimum Nutrition Serious Mass.

Each serving contains a whopping 1,250 calories (that’s if you mix it with water), a massive 50g of protein (fast acting whey and egg and slower acting casein), 250g of carbohydrates (20g of which are sugars) for boosting muscular energy stores, 4.5g of fat (1.5g of saturated fat) and 1g of Creatine Monohydrate.

Also included is L-Glutamine and glutamine peptides to aid protein synthesis and prevent immune system depletion, 25 vitamins, minerals, medium chain triglycerides and various other essential nutrients.

Optimum Nutrition Serious Mass is available in Banana, Chocolate, Strawberry and Vanilla.
