Serious Mass

Only 5.4kg Chocolate flavour is Informed Sports approved!

ON’s Serious Mass is the ultimate weight gain formula. If you find it difficult to gain weight, Serious Mass can help you develop the physique you’ve always wanted! Without adequate calories and quality protein, you simply can’t get any bigger, without enough fuel and muscle-building nutrients like protein, you simply won’t grow! Enter Serious Mass…

What Does It Do?
Each delicious shake delivers an incredible 1,250 calories, but no added sugar. This includes 50g of blended protein to support building muscle and 250g of carbs to fuel your workouts. That’s serious calories, serious protein and serious carbs…that’s Serious Mass!

Increase performance during high intensity training

3.4 g of pure Creatine Monohydrate to increase muscle power.

Mix with water, juice or your protein shake.

Amino Energy 270g

Informed Sports approved flavours – Fruit Fusion, Cola and Orange

Everybody wants a lean, muscular physique. Like anything worth having, wanting it isn’t enough. You have to commit to a rigorous diet and training program that will tax your strength mentally as well as physically. To help you satisfy both of these demands, ON’s Essential Amino Energy combines the optimal ratio of rapidly absorbed free-form amino acids with natural energizers and N.O. boosting ingredients to help you reach your next level – including muscle-building BCAAs and arginine for more intense, vascular pumps. At 10 calories per serving, it’ll make a big impression without denting your diet.

Fish Oil

Fish Oils contain long-chain fatty acids, with equally long names like docosahexenoic acid (DHA) and eicosapentaenoic acid (EPA). DHA and EPA are essential fats that cannot be made by your body. So, consuming them through foods like salmon and supplements such as the Optimum Nutrition Fish Oil Softgels is the only way to get DHA and EPA. Better yet, Fish Oil Softgels are enteric coated, which means that you get all of the benefits of fish oils without the fishy aftertaste that you might encounter without this special coating.

Directions of Use

Serious Mass

Add 2 heaped scoops of Serious Mass™ to a blender filled with 710ml (24oz) of water. Blend for 45-60 seconds, then add a few ice cubes and, if desired, calorie-contributing ingredients.

Tips: Mixing 2 scoops of Serious Mass™ with 710ml (24oz) of skimmed or semi-skimmed milk will give you a thicker, creamier, higher-calorie shake. New users may find it beneficial to begin with ½ of a serving daily for the first week, and then gradually increase to 1 or more full servings several times a day.

Serious Mass™ can be used to feed serious calorie needs in a variety of different ways.

Between Meals: Drink ½ – 1 serving of Serious Mass™ between meals to support a high calorie diet.

Post-Workout: Begin drinking ½ – 1 serving of Serious Mass™ 30-45 minutes following exercise.

Before Bed: Drink ½ – 1 serving of Serious Mass™ about 45-60 minutes before bed to provide nutrients to muscles throughout the night.

For best results, use Serious Mass™ combined with intense weight training (3-5 times per week) and a sensible, whole foods diet.
