Trib isn't going to boost your test enough to be any problem. I would also take ZMA along with the trib. Those are both legal, and legal in the military. I think you can even get them at the PX.
You will feel better on both of those, more energy, increased libido.... You will probably put on a little more muscle than without, but it is not going to be too dramatic, and you will have to have a lot of perseverance before you can actually see the difference.
I think the stuff is useful though, I still use it between cycles. The banned prohormones are a little better though. But man I must admit, whenever I tried the real thing, the difference was so freaking remarkable, I could never get excited about anything but real gear after that.
