You want to control estrogen on cycle with adex. At this dose, I might start wih .5mg EOD and possibly go to 1mg ED if you feel bad stuff coming on. You can take more than that, I'd say up to 1mg ED if you find that you still get gyno, but really I would not expect it from 250mg test even with less AI than .5mg. Remember you dont want to pull the E out. If you suffer from prolactin sides, caber at .5mg 2-3x wk should be plenty
