Benefits

Optimum Nutrition Serious Mass is a premium mass gain protein formula designed to support muscle growth and weight gain. This product provides the necessary tools to help individuals hit their calorie goals and put on size. Whether you're struggling to consume enough calories, have a highly active metabolism, a weak appetite, or an on-the-go lifestyle, Serious Mass protein powder can support your mass gain goals.

What sets Serious Mass apart is its comprehensive blend of high-quality ingredients. Each 2-scoop serving delivers 1,250 calories and 50 grams of blended protein to support muscle growth and tissue repair. This powder contains a combination of whey concentrate, whey isolates, casein, and egg proteins, ensuring a diverse amino acid profile. These proteins work together to aid muscle growth and support. Serious Mass also provides a substantial amount of carbohydrates, with over 250 grams per serving, all without any added sugar. Additionally, this product includes 3 grams of creatine monohydrate, which supports muscle strength, power, and size when combined with high-intensity activities. Moreover, Serious Mass is enriched with 20 essential vitamins and minerals, including L-glutamine. These nutrients further enhance the formula's effectiveness in supporting weight gain and overall health. 

This product is suitable for individuals who struggle to consume enough calories from food alone and are looking to establish a calorie surplus. Whether you are an athlete, bodybuilder, or someone striving to achieve weight gain goals, Serious Mass can help meet your nutritional needs effectively.  Available in a range of sizes and delectable flavours, Serious Mass is best enjoyed as a post-workout shake or a meal replacement between meals. It offers a convenient and tasty way to support your muscle-building journey and reach your weight gain goals.
