1. Eat lots of red meat the day before and day of the test.
2. Drink tons of water from the moment you wake up.
3. 1 1/2 hours before the test, drink a bottle of QCARBO. This step is very important because it will offset the dilution and give your urine a natural color.
4. Don't go to the test until you start to pee yelow again.
5. Use only the mid stream of you piss. Let the first and last go into the toilet.

Do a test run at home and good luck.
