Any Anastrozole Non-Responders?

Anyone ever heard of a poor or non-responder to anastrozole? I have been taking between .5-1mg ED and my most recent BT has my E2 at 59pg/ml. Some other numbers from the same test:
Total T 1415 ng/dl
Free T >53.0 pg/dl
SHBG 8 nmol/l

I have been reading this forum for a couple of years now and I know well the posts of KSMan, Happy Dog and others. I do not recall ever hearing anyone say that anastrozole did not work for them. Yet here I am. Thanks for any comments.

If you’re using liquid adex, there’s a possiblility it’s underdosed. I believe there’s a few threads here questioning the actual dosing of a certain brand that guys use.
