For starters, screw the T-400 crap and just stick with the cyp.
You can add an oral like tbol if you want to, but IMO, that's just going to be more for "the now" not your long term goal. If you're looking for big size and size that you are going to maintain for a while, while competing, bump up your test, to 1000mg/wk, and in HGH and/or IGF...preferably both.
Something else you can do for the AAS portion of your cycle, at wk 12-14 drop the deca and switch to tren...maybe run it until wk 22 or so.
