Optimum Nutrition Serious Mass

The formula of Serious Mass by ON is primarily aimed at building muscle mass. This product is ideal for individuals who struggle to gain weight and supports the increase in body size as well as the development of body composition. To gain mass and weight, one must provide the body with enough calories. Sometimes it can be challenging to meet the increased nutrient needs adequately to build muscle tissue and add more weight. Serious Mass was developed for such cases. For individuals with a fast metabolism who are also very active during the day, it is indeed practically impossible to consume the right nutrients in sufficient quantities through conventional diet alone. Thanks to its calorie-dense formula with high protein and carbohydrate content, along with a comprehensive range of added vitamins, minerals, and essential nutrients for muscle growth, Serious Mass meets this need. Each serving contains 1250 high-quality calories and delivers more than 50 g of protein and 250 g of carbohydrates. Serious Mass can be consumed as a snack, post-workout, or simply as a meal replacement, making it an ideal companion for anyone who is ambitious in the gym.
