Axe & Sledge Demoday is a peri-workout carbohydrate powder which means that it can be used before, during, and after training. Unlike most carbohydrate powders that use cheap dextrose or maltodextrin, Demo Day utilizes three trademarked/patented carbohydrate sources that are easy on the stomach and spike your blood sugar levels. In addition to carbohydrates, demo day contains several ingredients that boost performance, pumps, hydration, and carbohydrate uptake. This aspect of the formula is what sets demo day over the top when it comes to carb powders!
