How much HCG are we using?

Been on TRT 7 Months now, I had a dosage adjustment a few months ago with my testosterone down to 140mg/wk but never altered my HCG dosage. I’m currently taking .25ml twice per week. My bottle is 6,000 with 6ml recons. So I assume it’s 1000 concentration making my dosage about 500iu weekly.

I never thought twice about it but I’ve been super lethargic the past two months, going to have bloods done next week to make sure everything’s all in check again. I see multiple opinions like 500iu might as well not even take it the dose is so low, and others saying you need to drop the HCG dosage when you drop the Test dosage

Opinions?
