It does have some activity at the hypothalamus and as such will cause a slight increase in GRH,but clomid is much more effective for this purpose.Arimidex is quite potent for increasing T and FSH production.
no need for nolva and proviron post cycle with your clomid, just run clomid and anastrozole if you can. .5mg a day anastrozole should be plenty but you could always run it at 1mg as well if your not concerned with the cost.
