How can a win-win situation go terribly wrong? What little details can ruin everything?

- Hi, I have a question for you: is it possible to fail a drug test when using synthetic urine?
- Absolutely not – premixed synthetic urine is a 100% clean sample.
- Well, I haven’t used the premixed urine, I had that dry thing, you know, the one that you have to mix yourself?
- Oh, we don’t have that product and I can’t really give any information on it…
- My sample came up adulterated, and I’m not sure if it is because of how much water I put in it, if it got diluted, or what happened, but I just want to make sure that if I get your stuff it will work for me.
- Where did you get the water to mix it?
- Just regular tap water – I actually got lucky, I heard that they shut off the faucet before they let you in.
- Substances like fluoride can be used in public water systems that can show up as an adulterant. In a pre-mixed urine the bottle is sealed and nothing gets inside the sample, so it is unlikely to come up diluted or adulterated in any way.

If you are using anything besides what’s inside of sealed bottle, make sure that will not alter the sample. Pre-mixed synthetic urine provides a pure sample that guarantees successful test results.
