In regards to testing for the creatine, you can buy adulterant strips which have ph, creatine, and a few other tests on the strip as well. Basically, you dip the strip in the urine, and the 5 or 6 small squares on the strip will all turn a different color. They provide you with a chart which indicates what each color means, and this is how you can see if your creatine levels, and ph levels are normal or abnormal.

Suppose I drink 48oz of gatorade before the test. Should I drink all this at once, or should I stretch my fluid consumption out? Do I want to stay away from coffee? Will drinking 48oz of water give me abnormal creatine levels?

Thanks for the advice, much appreciated.
