Well, im sure some of our older guys can explain in even better detail than me, but to sum it up, Waxy Maize repleneshes glycogen stores faster than dextrose or any other carb. It also has a very high molecular weight, and low osmolarity, meaning it passes through the stomach very fast and gets absorbed by the intestines quicker than other PWO carbs. WM can also help you absorb other nutrients with it better (creatine, bcaa's, etc.) since it helps them pass through the stomach quicker and get absorbed better into the muscles. Waxy Maize is also sugar free and a complex carb, therefore it causes no bloating, and can be used when dieting. If you cant get a hold of waxy maize in Australia, vitargo is essentially the same thing.
