Like, what the hell is creatinine, urine.....this doesnt mean URIC Acid does it?
No it does not.

Creatinine is the end waste product found in urine that is tested for in determining an overdiluted sample. The labs will also test the creatinine level to see if a non-human sample is being used.

Creatinine begins life as creatine. Creatine is found in all human muscle tissue. As the muscle tissue is broken down and rebuilt, creatine is metabolized into creatinine and exits the body via the urine.

In order for the urine sample to be satisfctory, the creatinine level must be over 20 mg/dL. Urine samples with a creatinine level between 2 - 20 mg/dL are ruled "too-dilute" . A urine sample with a creatinine level under 2 mg/dL is ruled "not consistent with human urine" (aka 'substituted' specimen).

When doing any creatine loading (via the use of creatine supplements, fish or red meat consumption, etc) it must be understood that it takes 2-3 days for the body to metabolize the creatine into creatinine in order for it to be present in urine.
