Product description
Optimum Nutrition Serious Mass (5450g) is a high-calorie weight gainer specifically designed for athletes and fitness enthusiasts who want to increase their muscle mass quickly and effectively. The nutrient-rich blend provides complex carbohydrates, high-quality protein, essential amino acids, and vitamins and minerals to optimally supply the muscles and support muscle growth after intense training sessions. Serious Mass is ideal for people who have difficulty consuming enough calories through their normal diet and want to maximize muscle growth.
Ingredients & Features
The composition of maltodextrin, dextrose, and high-quality protein sources ensures a fast and long-lasting supply to the muscles. Each serving provides a high amount of calories and protein, supports regeneration, and delivers essential nutrients that are important for growth and health. In addition, the product contains a variety of vitamins and minerals that promote metabolism, the immune system, and overall well-being. The creamy consistency and pleasant taste make consuming even larger quantities particularly enjoyable.
Application & Dosage
For optimal results, it is recommended to stir one serving (two measuring spoons) into 600–700 ml of water or milk and consume it after training or as an additional meal. The portion size can be adjusted according to individual caloric needs. Regular intake, especially during intensive training phases, supports targeted muscle growth and an increase in body mass.
