Great!

I'd say try the Arimidex the way they prescribed at first. I'd then suggest getting bloodwork around day 5-7 from your test pin to see where everything is at and tweak it if need be. I'm guessing that they have you taking the dose on days 1 and 3 because your Aromatase will spike the most the first few days after your test pin, but again...that's just an assumption.
