From all I have seen on this subject here is a summary on beating a drug test: Beat The Piss Test Water >>>Drink a lot of water/juice the day prior to the test. >>>Drink 2 quarts a few hours before the test. Note: You may want to add pectin to water. See pectin below Pectin (Certa or Certo) Found In Supermarket Canning Supplies for Making Jelly Fruit pectin is a soluble fiber that binds and passes bile acid through the colon. Some people swear by it. I've heard rumors about people who smoked right up to the day before the test, consumed fruit pectin (a canning substance similar to Certa), and passed the test. However, there hasn’t been any test to validate these claims. >>> Drink 2 packs (1 box) of Pectin with a bunch of water the day before and the morning of the test. Creatinine Creatine can be bought at GNC stores Creatinine levels drop below normal when people dilute their urine by drinking a lot of water. Tests ensure that the subject didn't drink unusual amounts of water. Eating red meat will bring up creatinine levels or you can >>>Use 10 grams of Creatine 4 times a day starting 72hrs before your test. Color If a urine sample looks clear, the lab will suspect that it's watered down. They may reject the sample. >>>Take vitamin B complex to color your urine yellow. B-2 or B-12 (found in B-complex vitamins) are the most effective, though some will argue that vitamin C is better. Fiber "THC is eliminated primarily in the stool via bile acids. Thus a person with a high fiber diet will excrete a majority of THC [metabolites] in the stool" >>>A fiber-based laxative will also help to cause the THC metabolites to be excreted in the stool Exercise When fat is burned, THC by-products are released into the blood. Exercising between drug tests will clean THC metabolites from the system at a faster rate >>>Exercise increases the amount of THC metabolites in the urine. >>> Quit exercising a week before the test. Be lazy, and eat big. Aspirin >>>Taking 4 aspirins a few hours prior to the test might help you. Aspirin is said to interfere with the test. It seems that aspirin absorbs at the same wavelength that NAD does which is how it interferes with the assay. Sugar >>>Consume an ample amount of sugar on the day of testing. This will slow down the burning of fat. Pee Stream Don't give urine from your first urination of the day. It's the dirtiest, and can be heavily filled with metabolites. >>>Urinate at LEAST 2 times in the morning before the actual test. >>>Don't give the beginning or end of the stream. Piss in the toilet, then quickly stop and go in the cup. Stop, and shift back to the toilet for the last portion. Only give a midstream sample. Just be sure to give 60 cc's.
