If you fuck up your HPTA, then you can come back here and talk about TRT.
1mg Arimidex/anastrozole is good for 100mg T per week and will not be enough to manage 500mg/week. Inject T twice a week and take 1.5mg anastrozole at that time. You need lab work to do things right. Your PCT is dangerous because you do not know anything about it, and most of what you will find will be wrong.
