What dose are you running it? Test U is a great option, it takes some time to build up though so better spend some time in steroid plotter to find when to start and with what dose. For a long term plan is the best solution, but if you're planning to work there for like 3-5 months and then return to normal habits and pinning i'm not sure it worth it, the time it takes to build up and the time it still lingers in the body after last pin is kinda meh to estimate and dial in.
A second option and i know some guys might cringe a little, is to buy some test E in castor oil and spread a good dose subcutaneous before you enter the camp. Even if you shoot it IM you'll probably be fine for 2 weeks since castor oil dispurse very slow, i just think by lowering it more with subc you might not have to deal with side effects from the bolus dose and faster peaking in serum.
There's still many TRT clinics who have their patients doing one shot every 2 weeks, so don't get too worried about it. Just make sure you can sneak some AI in your multivitamin pills to have for your 2 week periods.
I believe you're doing the right thing though, i'd be so anxious with carrying gear with me that sides from the test trough would be childish compared with my fear not to get caught.
