HCG “catch up” dose on test e cycle

[Mlitalie]

Hello all-

33 year old male
6’0 210 lbs
18% ish BF
12 year training history including powerlifting and bodybuilding
Cycle history: sustanon x 8 weeks with PCT 8 years ago
Current cycle: test e 500 EW and aromasin 12.5 mg EOD. Just finished week 3 of 12. PCT clomid 50/50/50/50 nolvadex 50/25/25/25

Question:
From what I was reading when starting this cycle is I should do HCG the gap between last test injection and up until 3 days prior to PCT, however the more I continued reading the more I see recommendation of HCG during cycle.

I want to start HCG now, do I need to take higher dose to catch up and reverse my current testicular atrophy (which I’ve read) ranging from 1000 to 5000 iu first week then 250-500 iu bi-weekly up until 3 days prior to PCT. Or, can I just start 250 iu bi-weekly (500 iu weekly) until 3 day prior to PCT. any thoughts or suggestions greatly appreciated about any aspect of the cycle or PCT.

Also, when would I stop the aromasin?

Thank you for your time!
