Just got some dextrose for my pwo shake. I have been taking 2 scoops of ON whey immediately following my workout. I was wondering how much dextrose I should add to my shake. I read on a previous post that 50-70 g is good. How do I measure 50-70 grams? I used a converter on the internet and it says 50 g is approximately 3.5 tablespoons. Is that correct
