Weider is a synonym of health, expertise and results. The oldest quality brand that has been athletes since 1936. Athletes have deposited their trust for more than 80 years and we have supported you to achieve your goals. Times change and science makes progress. Mega Mass 4000 has adapted to the new times to continue offering the best product to grow muscle mass and volume.

Mega Mass 4000 provides high-quality energy and protein to cover all the needs of the most demanding athletes and exigent trainings. We have drastically reduced Mega Mass 4000 sugar content and have created instead a supply of energy to the muscles that need to grow. Its exclusive mix of sugar free carbohydrates are made from a base of corn maltodextrin, native wheat starch, whole oat flour and native potato starch.

The carbohydrates sum up to 69% of the formula with only 13% of sugars. Mega Mass 4000’s matrix protein is made from milk protein isolate, which supplies casein and whey, whey protein concentrate, and egg white protein powder. This combination of fast and slow protein aids a fast as well as a lasting recovery, which guarantees 100% natural anabolism and muscle mass gain.

To refine our formula, we have added 3.4 g of Creapure®, creatine monohydrate, which boosts performance and strength while contributing to gain muscle volume. Likewise, 8 vitamins and 3 minerals have been added to optimize the body’s ability to incorporate the benefits of training.

Mega Mass 4000 is the ideal companion that provides all the nutrients that your body needs so that you only focus on training to the max!
