Bonez is correct, your questions could have been answered with a simple search, you should have researched all of this prior to starting your cycle; but it's too late now.
Since I started, I'll finish...
HCG should NOT be used for PCT. It should have been administered throughout the cycle at 250IU twice a week and stopped around the time of the final shot.. Just save it for next time.
Starting PCT 10 days after last shot having used Cyp and enan is fine. I personally would use 150mg clomid a day for ten days, then 100mg a day for ten days, then 50mg a day for another 10-20 days.
I ALWAYS preferred clomid over nolvadex for PCT, but that's just me.
If you have Nolvadex, I would run 40-60mg a day for the first 10 days, then run 20mg a day for at least another 10 days, I would run PCT for 30 days.
