When you inject every 10 days, T levels get very high then fall low. So your levels of E2 in you blood change greatly. E2 is from FT-->E2 and that rate depends on your FT levels that are changing. You need anastrozole to control FT-->E2, but that dose needs to match your FT levels. That is mostly impossible because your T levels change greatly.
Nolvadex is a SERM and SERMs do not decrease E2, SERMS increase E2.
Your protocol is bad.
I think that you create a lot of E2 and T levels drop then you feel bad with high E2 and falling T. Your E2 cannot be crashing.
Are you able to self-inject? Best to inject T twice a week.
