With 200mg T per week, many would need 2.0mg anastrozole per week.
So lets assume that you are an anastrozole over responder.
Stop anastrozole for 5-6 days for 4 half life washout
Resume at 1/4th the expected dose, 0.5mg a week.
Inject T twice a week and take 0.25mg at time of injections.
Please post your lab work and ranges. The advice above assumes that you have high T levels. If not, need a different plan.
