to much of supplements can make you fail a test.mainly creatine..i have failed because of a negative diluted sample just for having to much whay/trac creatine in my system.
This is incorrect. A urine sample is ruled "diluted" when creatinine levels are low. A urine sample with a creatinine level of 2 - 20 mg/dL is ruled diluted. There are no upper limits established for creatinine, so therefore a lab cannot flag samples for having high creatinine. As long as the creatinine level is over 20 mg/dL, its satisfactory.
