How much creatine you need to take all depends on what your "baseline" creatinine level is before diluting - and each persons baseline is different - and you will not know what your baseline level is without testing your creatinine level with a drug adulteration test kit.

Be noted though that there are no upper limits established for creatinine. As long as the creatinine level is above 20 mg/dL, its satisfactory. However, this does not mean you should go crazy with creatine-loading. Going overboard on creatine supps can result in long unwanted bathroom sessions, sitting on the toilet seat.
