army+ detection

First and formost im US army. I love powerlifting and I want to put on more mass... quicker then naturally. My questions are they piss test us randomly. I dont want to get detected, like anyone woudlnt want to. Is there really anything that I could take to help me gain more strength(with it comes mass) without being detected? I dont care the price. Before I joined the army I used sus250/decca/dbol and had wonderful results, i went from 190 - 219 in 10 weeks, then back down to 212.
Ive read in magazines and internet sites the stuff you can take that " a branch chain away from being a real steriod, just legal" and I allways though that was rubbish but - i just thought I would bring that up too, as I have thought about it to much.

Thanks for advise btw

PS. any alternative suggestions where I could take a short cycle with something that woudlnt be in my system for very long - if I get daring and want to take a risk?

Well in response to what you said, you are correct in your assumption. The general "piss test" is for what you said, but they do admit random steroid tests at their discression. If I find out exactly what kind of test it is, is there a way around it or perhaps(like I asked before) other steriods that wont be detected?
