Sounds to me like you are running too much AI and now your low. It takes time or many blood tests to figure out how to you arimidex. And by the way Liquid arimidex is very very common and I don't think I have ever run across any bad stuff. I actually had to use up to .5 eod to control my E3 on only 120 mg of test a week. Most get away with much less than that. If you wake up in the morning with a hard on then you probably have your E3 where you want it.
