I would get on HRT and then get the test elsewhere. You win because you've got the scrip. No more worries about law enforcement (at least with the test).

About the cycle, I would structure the deca so that it is tapering out of your system while you are still running the test. I always run deca this way and it eliminates the deca shutdown issues due to the decanoate ester. I would also run hcg intermittently throughout the cycle to prevent testicular atrophy. Doing so will enhance post cycle recovery.

If you really wanted to get fancy, you could throw in fast acting stuff on the back-end and time it so that everything clears at the same time.
