To add to my previous comment, I dont think it comes down to which estrogen blocker to choose from. My estrodiol went from the 90s down to 14 so Armidex works. The problem is now just getting it back up which means stopping while I take T injections and seeing where it goes up to. After not taking T shots or Armidex, my T levels dropped low but estrodiol stayed the same and did not go up naturally from 14. To me this means stopping Armidex and letting the shot convert to estrogen a little bit higher. What do you think about that?
