First How many grams are in a 1/2 cup? 100? Does anyone know how many carb grams are in the Dextrose powder at Pro factory. Is it 92 grams per 1/2 cup or is it 74 per 1/2 cup? I called pro factory and the women said 74 per half but SHE could have been mistaken she had to put me on hold to look up the information. I could see a mistake happening there. ANYONE?
