Woah, ok not to start an arguement or anything, but as I always understood it sucrose is composed of 2 sugars (hence mono being the prefix for each individual sugars, and di being the prefix for sucrose, saccaride of course meaning sugar). But yes it is a unique sugar, and dextrose being the only component normally found in blood. Where as fructose is carried to the liver first to be broken into glycogen, glucose, and 6-gluc.
I don't think that shooting it would have any bad effects though. But for the sake of harm reduction I don't think it should be done.
Again, not trying to argue, I know for a fact you are probably smarter than me, and no Im not being sarcastic.
