Oestroen doesnt always correlate to SHBG...
I think the important thing is to be sensible.. You dont want to be flatlining oestrogen. It has its place.
However some people simply have different hormone metabolism. So someone may require 0.5mg adex daily on NORMAL trt dosages of say tets enth and another person can shoot 500mg week no issues.
The important thing to do is rememeber you are unique. Monitor your bloods and take adex only when you need it and not for just no reason. Once again like everything with the body it depends on the person, there is no 1 size fits all.
