in my personal experience (and yes ive had a lot) the only thing that helped my gyno is arimidex
im actually on epi now and by the time i wake up every morning gyno is back stronger then before!!!
im actually going quite high on it though because the effects just seem to keep getting better... sooo ill be at 70mg for another 6 days then 80 for a day then 100 till the end.
even at those doses gyno seems to be a problem and i take adex every night before bed as well
