Query: What is this for?

I ordered this product believing that it was one of the "Isopure" protein powder products. Oops, this is not protein powder, it's carbohydrate powder with a little protein. Perfect when you can't expand your spare tire fast enough, or your blood sugar drops below 250 or your arteries start to clear out.However, nutritionally, it's not much different from white bread. Not sure why you would use this when cake and donuts would be so much more fun.Seriously, there was no nutrition info on the Web page and the manufacturer's use of the "Isopure" label is certainly misleading. I'll use other brands in the future. As a side note, Amazon should really include a link to the full information on products like this. I hate to have to do a Web search for every item I look at.
