Well I actually like your protocol.
This is the only thing I would change:
(weeks 1 - 12) Test-E @ 300mg
(weeks 1 - 10) Tren-E @ 500mg
^^ I prefer to keep the Tren dosage lower; It's the most powerful AAS for a reason, you might as well run a low dose of test, and allow the tren to do all the work (and change your body!)
Honestly though, you may want to start at a lower dosage, and bump it up (if you feel you're ok with the side affects). I wouldn't recommend starting off with 500mg, because chances are you'll get owned by sides
