Well here we go again, but I hate to say this, chances are (and I am a pessimist) he will not be fine. He is in law enforcement, and if they are going to test him for steroids they will not only test the test/epitest ratio but will also send the sample for gas chromotagraphy/mass spectrometry. It's a city, state, federal, or county agency, they don't care about the $, if they plan to do the test, they do it and they do it completely. A city with a multi million dollar budget isn't gonna care about spending a few hundred dollars to a thousand dollars to find out if a member of law enforcement is violating departmental substance abuse policy. How would I know anything right? Well I have first hand knowledge in that aspect, and at the time I thought they too would just look at test/epitest, but it just doesn't work that way.
Tren is a derivative of nandrolone and will show up as such on a test.
Pelon, if you are truly worried, refuse the test, and if you are at high risk of losing your job, claim you are addicted to juice, under the ADA your department will be required to provide treatment for your "addiction." If you take the test and are found to be positive, it's too late for ADA to cover you. If I could go back in time I'd have done this and I'd still be in law enforcement.
This of course applies if you are a member of a law enforcement agency in the US. If you're in Canada, I have no idea what their practices are.
Either way Pelon, good luck.
