1) Bring the test up to 600mg ( more is never better) I know alot of pros and worked with a few gurus in the business for contest prep...and the level of test that you guys use on this forum is for a pro that has been a pro for 5-10 years...
2) Eq is perfect as is.
3) Orals are not needed, the stress you put on your body is not worth what you get out of it.... if you want to run an oral the best is Anavar 8 weeks,,, since it is not toxic to the body. But of course always make sure to get your milk thistle and cranberrry extract. (take note, anavar will start working at full speed at the 2nd or 3rd week, so a 3 week run will do you no good.
4) Run a half of pill or Arimidex EOD (the whole run): some people will tell you wont make as many gains, but as they may not know you will shift the balance of muscle vs fat..by keeping the estrongen under control,, in turn changing the ratio that you currently have in the body...because if not the higher estrogen in your body will make you gain more body fat as you increase your lean muscle tissue.
5) there alot of way to run the PCT, but yours looks good enough.
The other adivise,,,, due the run for 15-16 weeks because the test will not be 100% in your blood until the 3rd week, and same for the Eq. (Eq may take 4 weeks for a 100% concentration, for some)
