We know that you want to work to the maximum during training. This will definitely require determination, motivation and the fire that drives you throughout your training sessions. This is the most important ingredient. However, if you want to maximize your potential, you need to be properly energized to keep up with a long training regime. Supercarb Xpress contains five sources of carbohydrates with different rates of assimilation — slower and faster. It has been scientifically proven that performance during long-term workouts is hindered by limited glycogen reserves in the muscles. These reserves can be better replenished by higher carbohydrate intake. More replenished reserves = more effective training. It's so simple.
