Dude how the hell old are you? You just out of high school and enlisting? If so you need to re-evaluate some things in your life....especially just planning to be juicing at your age already, especially being in the military....
They probably wont test for it because its so damn expensive...if they do ever your screwed anyways, Deca can be in your system for 18 months or so....worst roid to take for someone being tested.

I doubt they test hormones either, thats a pretty penny and why would they?
Go eat some steak, PBJ, drink lots of milk, throw down protein shakes, and get in a rack doing some powerlifting and a platform doing some olympic lifting...no need to juice if your under 25.....if you are in your teens you have a better anabolic environment than any needle your gonna stick in your a$$, so take advantage of it and your nervous systems ability to fire efficient as heck right now...save the sauce for when you are out of the military, or if you end up spec ops down the road and spending lots of time overseas in bad places killing bad men, and need some recovery to keep your motor running while deployed. Not now for heavens sake...
