21-year-old – 600 mg Test C for 21 weeks (with 500 IU HCG EOD)

I’ve been running 600 mg/week of Test C for 21 weeks, along with 500 IU HCG every other day. I do plan to PCT and come off — I’m not trying to stay on permanently — but I’d like some opinions on timing.

I have an event in early June that I’d really like to look good for.

My main questions are:
1. How much harder would PCT realistically be if I extend this cycle a few more weeks? If I did, total cycle length would be around 36 weeks.
2. Would it be safer or smarter to drop down to TRT-level dosing until June?
3. Or should I PCT now and try to have my natural levels stabilized by early June?

I understand this hasn’t been the smartest approach, but I’d really appreciate honest feedback from those with experience.
