One of the original methods of avoiding detection is to buy synthetic urine and substitute your urine with synthetic one. This works very well if you're not supervised. Another problem is that labs know what the temperature of a fresh urine sample should be and they also know that a sample should have blood particles in it of the blood type of the person being tested; so it is riskier to try and evade the urinalysis test by using a urine substitution. But if you don't have enough time for other way, this method is the only.

The other way is to clean your body from toxins and to pass the test in natural way.

First of all, cleanse your system - the way this is done is to drink a very lot of fluids and urinate as frequently as you can. This will dilute the concentration of THC metabolyte in your urine. Start washing yourself out days before the test, that is preferable, although it is much more important to do it hours before the test.

Exercise. As we know, THC stores in fat cells - exercises are burning fat and THC byproducts are released into the blood and urine that goes out while you cleansing your system. But it is important to stop burning fat cells near test time (up to 48 hours before your drug test). On test day, it doesn't matter what's in your lipid tissue. What's in your blood and urine does matter.

Eating foods rich in protein like red meat will slightly increase creatinine levels. Creatinine is a substance in urine, it level drops below normal when people dilute their urine. Labs test creatinine levels to ensure that the sample is valid and the subject didn't drink unusual amounts of water.

There is testing industry data that aspirin interferes with the chemicals in the test, so taking 4 aspirins a few hours prior to the test might help you.

If a urine sample looks clear, the lab will suspect that it's watered down. They can't report it as positive, but they may reject the sample and inform your employer that you tried to beat the test. To avoid this, color your sample yellow by taking vitamin B. The most effective vitamins B-2 or B-12 you can find in detox drinks and detox pills that are selling in our store.
