Optimum Nutrition Serious Mass 5.4kg (12lb) Benefits Huge servings to maximise weight gain 50g of a blend of proteins to maximise protein synthesis Additional glutamine for recovery Creatine for mass & strength gains Fibre included to aid digestion Full of vitamins & minerals to ensure health is optimised Tastes great Predator Nutrition Serious Mass 12lb Review Optimum Nutrition Serious Mass is a phenomenally popular weight gainer & Optimum's signature product when it comes to addressing the needs of bodybuilders who struggle to gain weight. Serious Mass is packed full of carbohdyrate, although the source of them, maltodextrin, may raise eyebrows in the quarter where a low GI carb source is preferred. We disagree because for weight gain maltodextrin will lead to faster gastric emptying which will allow for greater overall calorie intake. Using oats, or similar carbohydrate sources would actually make you feel full faster
- the last thing needed for the chronically underweight. Serious Mass uses a blend of protein sources including whey & milk protein which is ideal for providing a balance amino acid profile & balancing fast & slow proteins, while the inclusion of a small amount of fibre for health, alongside a vitamin & mineral blend is important given that users of Serious Mass may not have much room left for foods comprising these nutrients. Creatine & glutamine are both useful additions to help aid recovery & strength gains. Serious Mass is ideal for anyone wanting to gain weight fast. Where a slower pace of growth is preferred we would suggest a higher protein gainer.
