Most "normal anastrozole responders" need ~ 1mg/week for each 100mg T ester per week. A few, not rare, are over-responders who will crash E2 and need 1/4th the expected doses. With labs, try to get near E2=22pg/ml.
It takes around 6 days for a constant dose of anastrozole to reach steady state blood levels. You need to understand "half life". As you go forward, do not make snap changes in AI dosing as the truth takes 6-7 days to see what it will do.
Anastrozole is a competitive drug against T. T levels need to be steady and E3D is good. Try to dose anastrozole at times of injections.
