If gyno symptoms are flaring up I usually recommend Femara for a couple weeks at 2.5mcg per day until it subsides and then remain on Femara (Letro) or Arimidex for the remainder of the cycle at 0.5-1mcg/eod.
Letro and Adex are very similar but letro (femara) seems to do a better job of clearing symptoms up if they rear their head.
