Unless things have changed in the past two years since I got out, it was my understanding that they did not test for steroids unless you were command referred because the testing for steroid compounds is much more expensive than testing for other illegal substances...don't take this as gospel though, just some barrack's lawyer talk, check out the regs first.
I agree. They dont test for steroids unless the commander ask for it.
I agree as well. I'm a Marine and they will only test you if you are without a doubt juicing or run your mouth too much and someone turns you in.
