estrogen plays an important role in the body from what i read...it has something to do with the release of igf-1.....the question is how much estro should be blocked on a mass cycle of over 1 or 2 g's of test...blocking estro with arimidex or proviron seems block the release of igf-1.....so i am wondering if using clomid as a mild anti-e and then arimidex ever 5 days or so would be smart....there has to be a ratio to figure out how much estro we need in our bodies??
