You can try and take what the directions call for , then check your efforts 2-3 days later with a validity test strip. Do not overload on creatine supps as this can result in long unwanted bathroom sessions, sitting on the toilet seat.

Validity test strips are available online and they are not at all expensive. Do a Google search for drug adulteration test kits
Burnt Toast Reviewed by Burnt Toast on . Creatinine Levels Since I understand that there is no upper limit for creatinine levels found in urine when it is tested (if true), 2-3 days prior to testing is it best to just follow the suggested useage directions or to be safe should you overload as with the vitamin B2 as recommeded by N2?
