Dextrose speeds your insuline...it's a kind of cabohydrate which is converted very quickly but it makes you fat so don't take to much, but it's good when taken together with creatine cause it increases the creatine uptake.

By the way the best Creatine is made by SKW. It's a German factory and it's 100% pure. SKW kixx ass it's also used by Scitec and a few others.
