Anadrol doesn't aromatize, but does have estrogenic effect - so it can be tricky and if not managed can lead to weird sides.
My advice would be to manage the E on your testosterone base with the arimidex, so it's within range. If you do that then you shouldn't have any problems. I don't mean this as an offence, but if you don't know how to do that yet then skip the anadrol this time around and learn how.
Yeah if you start to get itchy nipples or growing lumps around your nipples then nolva will sort you out, but the general advice on this board is to keep the nolva for PCT and manage estrogen on cycle with adex or asin.
