If you're not using exogenous testosterone and your LH is still in the game, Adex actually might not crash the E2. Correct me if I'm wrong, but all the studies I'm able to find of Anastrozole in males, are done on a normal males with elevated E2. Doses have been 0,5mg or 1mg daily. In those studies it seem to decrease E2 around 50% regardless of the dose. So it significantly lowered their E2, but didn't crash. Unlike it does when on gear. I'm not sure if I'm able to post any links, but the studies are quite easy to find. Anyway, just something to think of.
