Optimum Nutrition Serious Mass (12lbs) Strawberry - Weight Gainer

Product Description

Serious MASS by ON is a formula designed primarily for building muscle mass. Ideal for people who have difficulty gaining weight, Serious Mass helps increase size and supports physical development. To gain mass and weight, it is necessary to consume enough calories. Sometimes, it is difficult to properly take in the increased nutritional intake required to build muscle tissue and gain weight. That is why Serious Mass was developed. In fact, for people with a fast metabolism who are very active during the day, it is practically impossible to obtain the right nutrients in sufficient quantities every day through a conventional diet alone. Thanks to its calorie-rich formula with a high protein and carbohydrate content, plus the addition of a complete profile of vitamins, minerals and certain nutrients essential for muscle growth, Serious Mass helps meet these needs. Each serving contains 1250 quality calories, providing more than 50g of protein and 250g of carbohydrates. Enjoyed between meals, after training or simply as a meal replacement, Serious Mass is the ideal companion for those with ambition in the weight room.

Instructions for use: Add 168 g (~ 1 heaped scoops) to a blender filled with 360 ml of water. Blend for 30-45 seconds.
