I am in the process of joining the Army, and am currently using test e. I went through meps a few weeks ago about 5 weeks into my cycle. I got blood drawn, piss test, the whole 9 yards. I wasn't caught by either test. The piss and blood test only test for 5 different drugs, or so the recruiter said, normal street drugs stuff. As far as I understand, the whole Army does something like a few thousand random tests each year from meps for steroids. It would be outrageously expensive for the government to pay for every person to get tested. But I guess our government does know how to spend money on useless shit lol. As far as them testing once you are in, they cannot just pick you out and test you, you must give them reasonable suspicion to test you. IE beating the hell out of people all the time, having an uncontrollable temper etc. There are plenty of people on steroids in the military. You just can't be dumb about it, don't trust anyone else around because you never know if you have someone who will rat you out and start the process of getting you tested.
