Arimadex 0.5mg eod 1-13
Pct 14-18

Just starting first week an nipples are a bit puffy. Not really sore a slight bit sensitive maybe.
Not sure if it’s just me though. Should I up the Dex dosage to .5 ED? As novla will kill the Dex off. If this is gyno it is early days but rather sooner than later.

Any help appreciated
