PCT (clomid) for Sust 250 - cant find these answers!

finish my last injection today.

Would like to know a couple of questions i cant seem to find answers to.

Ill be doing clomid for my pct

I know to wait 21 days

then ill be doing the following:

Chomiphene (Clomid)

Day 1: 300mg (this may be excessive to some, you're probably better with 200mg)
Day 2-11 (10 days): 100mg/day
Day 12-21 (10 days): 50mg/day

I have been taking HGC and arimdex during my cycle.

My questions:

on the 3 weeks wait before i start the clomid do i still take arimdex and/or hcg?

and when im on the 3 week course of clomid do i take the arimdex and/or hcg?

cheers.
