how much dextrose pwo

Given that the glycemic index value of slow cooking oatmeal is 70, would it be just as effective to use a similar GI value powder, such as lactose (65)? And would it be even more effective than oats, given the value of lower GI nutrients post-workout, to use a very low GI value powder, such as fructose (32)?

I am just talking out of my arse here as an avid lurker/reader, but from what I've gathered from the experts sources around the boards (Alan, Bobo, Layne etc) they would probably tell you even though the GI of said powder is low, there is probably little or no micronutrient value when compared to oats. Even though I assume it a milk derivative, because lactose is actually the sugar present in milk, I would assume it would not retain milk's other numerous beneficial properties.

As for the fructose, despite its low GI, I believe fructose tends to replenish liver glycogen not muscle stores. This would essentially cause a pretty quick spill-over in the BB'er, though I think it would have more useful application perhaps in endurance athletes?
