I have got Cell Tech Creatine includes a big scoop (51 g) inside the box. It is written on the ingredients label that the serving (1 scoop) contains 5 g creatine + 15 g sugar + vitamins + etc... As I know, I should take 5 g creatine a day but I got confused whether I should take (1 scoop of 51 g) per day mix it with water or I have to measure 5 g of the creatine powder by using the food scale ? Please help.
