How much Sustanton?
What E test was performed and what is the normal range?
I think what Couchlockd was questioning was the amount of Arimidex (anastrozole). For most E tests, 50 pg/mL is not all that high and 0.5 mg of anastrozole E2D is a whopping huge dose. I would be surprised if you have any E conversion, which is just as bad as having high E.
