IMHO, you didn't need an Aromatase inhibitor (AI) at 200mg a week, but 500 is a whole new ball-game! Get a mild Aromatase inhibitor (AI) like Anastrozole/arimidex and run it steadily at .5 e3d. You'll never know its there. And you'll feel good throughout your cycle.
And keep it simple, just run test at 500/week throughout. Changing levels change sides. It's hard to learn what you're doing if you don't keep things consistent.
And, BEFORE you start your cycle, buy your PCT drugs. You'll need Hgc, Clomid, and Nolvodex.
