Adex and HCG

[synman]

My 12 wk cycle is
500mg /wk Test-E,
A-50 at 50mgs per day first 4 wks,
Winny at 100mgs E.O.D. last 4 wks

I want to run Arimidex along with the Winny for last 4 wks
Also was thinking of adding HCG for last 4 wks.

How would you recommend the dosage for the Adex and HCG? And are they good to run together?
Also would I need to run nolva and clomid pct?
