Muscle king nutrition have designed this product with one thing in mind QUALITY.

Each serving gives you a mind blowing 36.9g of the highest quality whey protein concentrate (not cheap low quality milk protein which a lot of weight gainers use as their protein source) and 57.2g of complex carbohydrate (maltodextrin) Muscle king designed this product at the athlete wanting to put on good size but not wanting to put on fat as a lot of products on the market are made up of extremely high calorie formulas containing huge amounts of sugars and fats which are cheap to make and sold for ridiculous prices.

Muscle king try to give you the best quality ingredients at a realistic price. Muscle king boast their product contains zero saturated fat, only 7.8g of sugar and 3.8g of fat (Zero Saturated Fat) and it totally aspartame free making this product in our eyes the best quality weight gain product on the market place.

With the quality of this product you would probably think the product may lack in taste but the flavours are amazing. Muscle king weight gain comes in 4 great tasting flavours.
chocolate, strawberry, banana, vanilla and is available in a 2.7kg tub and a 5kg tub.

Muscle king weight gain can be used up to 3 times a day inbetween meals or as replacement . it can also be used as the perfect post workout recovery and muscle growth supplement.
