Need help with HCG to TRT ratio.

I've been doing 160mg TestC (split into 2 injections) with 500iu HCG (split into 2 injections) weekly.

I recently decided to follow the advice of @Nelson Vergel and increased my HCG to 1000iu (split into 2 injections weekly).

Feeling way better!

But after a couple of weeks I can tell my E2 is too high now. Libido starting to wane and really bad face bloat.

Trying to stay away from AI, so the obvious question is do I need to now reduce my TRT dose? And if so, by how much?

Are there any ball park recommendations like 1000iu HCG is equivalent to 20mg or 40 mg of TestC? So I know by how much to drop my T dose by?

I will be doing bloods in 3 - 4 weeks, but don't really want to deal with e2 sides until then.

@Nelson Vergel You've said that your current protocol is 100mg TestC and 1000iu (split weekly).

Did you have to drop your TestC dose as well to keep your e2 in check at that higher HCG dose?

And what does your current protocol put your total, free, and E2 at?
 
HCG May stimulate your body’s own production of test so now that’s compounding with your fairly high test dosage and creating this knock on response from your body. It’s likely you’re now producing more E2 than before. It’s one for your Doc really, but why guess? Get your bloods done now and check then consult with your doctor.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
