You'll need Arimidex. I don't think you will be in need of a Progesterone Antagonizer. If you can successfully keep your Estrogen levels in range, than your prolactin levels should be in range as well.
If you start noticing some puffy nipples, you can try adding some Pramipexole or Cabergoline.
So i will definently need arimidex? I have decided to do 125g test eod, and 50g tren eod. Thanks if i notice this i will definently add one of them.
