Didn't find anything relevant. But I assume you have no idea then?The search feature is your friend.
I'm going to run it soon due to pfs.No it is not. If you wanted to use a SERM or AI for a couple weeks after that is fine but definitely not required. Within a few weeks you should be in decent shape toward recovered LH after stopping hCG.
How long did you use it?
Run some labs and prove to yourself.
