Ok. A few things:

I don't particularly care for "ramping" up your dose. I've tried it. I think it's unnecessary.

I'm not concerned about your test dose if you're ready for it, but god damn 900mg/wk of deca. You won't feel good man.

I've gone up to 800mg/wk of deca and had to scale it back. 600mg/wk is a solid dose, yeilds excellent gains, and you won't have a shit ton of sides to deal with .

It's up to you with the Prov/aromasin thing, but it would probably be easier and simpler to just run an AI.
