If you have nolva and have already started running it. Just keep it going. Run it at 40mg along side of Aromasin at 25mg ED until you start to see improvement. IT WILL TAKE TIME!!!!! Then drop down to 20/12.5 and slowly taper off. It could take weeks or even months. But it will work!
Letrozol is just a very powerful AI and does not block estrogen from binding to the tissue in the breast.
Rolox is a SERM and WILL prevent estrogen from binding to the breast tissue. (That is what you want)
A combination of either Rolox/Aromasin or Nolva/Aromasin is what you will need to reduce gyno
