Can you buy pure carbohydrates or does it come in one of those muscle gain formulas?thanks a lot!
You can get it at several places. 2 that I know of are: micro-brewery stores (online or locally) or the Protein Factory (online). Both sell both dextrose (glucose) and maltodextrin.
Beer or wine making supply place. Get some maltodextrin. In bulk I pay about $2.00 per pound.
