there were a few post about month ago, one guy covered all the services.
in a nut shell. they do not test for juice, ubless you really look the part and act it. ie rage. most will look at 5-6% with sucle and skill a God sed. If you plan to juice b4 boot camp, you are most likly gonna piss it out. Get ripped nad strong (fin,anavar) fo the stamina you wil need. After boot, intro it gently, kep the muscleteck, GNC powers VISABLE, while you try and cycle. Best to keep off base, as your locker is not yours.
Oh they can test when ever and for what ever.. Estp if you plan anything special in the service. Do becareful, and wise.
