If you had actually read any of the threads you refer to, you would know that synthetic urine is often detected and nullifies a test.....
I'm not sure I follow.... how does a company that requires drug testing profit from requesting a drug test?
Synthetic urine is often detected in those that abuse one of the two following; 1. Do not properly set up for the synthetic to be used, ex. not heating properly (90% of detections are due to degree) and/or 2. They had an outdated setup, the drug testing industry is huge & they are constantly updating they're methods in order to better detect not only drug use but synthetic use. Therefore, likewise, the synthetic companies who are also a large industry are putting just as much study to stay above the testing facilities. Just like the doctors that put more research into coming out with a steroid that won't be detected for athletes.
With a trusted synthetic brand, up to date, & used properly, you will pass 100% of the time, guaranteed. I'm walking proof of that, I have used a handful myself. The company I use to work for did random drug testing twice a year. I've had my fair share of testing synthetics.
Everybody profits in the drug testing industry, little research on Google or even Yahoo for that matter will open your eyes. Drug testing for employment is one of the biggest scams being ran with little detection. It amazes me really, something so obvious... yet so misunderstood.
