With your dosing, I don't think you would need more than .5mg adex EOD. That should be plenty and with this, your esotrgen should be fine. If you start to have any itchiness around the nipple, increase the adex to 1mg for a couple of days, then back it down, taking a little more than you were before and you should be fine.
For PCT, 2 wks after last shot, 100mg clomid for 1 wk. Then 14 more days at 50mg If you like, you can continue running the HCG right up to the point that you start the PCT meds
Think you have been over thinking it
