Does HCG suppress to the same extent as exogenous testosterone? I want to take HCG for fertility reasons, but when I come off, will have low T levels?

I want to run HCG in order to improve my fertility numbers. I’ve got 3 10,000iu bottles of HCG that my doctor prescribed for me, but I’m concerned that taking this will suppress my own testosterone production…leaving me low T or a need for a “PCT” once I stop the HCG injections. Am I off base...

Is GnRH suppression hurting us?

Is it true that low-dose TRT does NOT suppress own production?

I‘m currently FURIOUS about my doc. Grrrrrr.... Backstory here. Anyway - is it true that you can give low-dose TRT as an „add-on“ in a low-enough dose that does not suppress your own production? My impression was that ANY exogenous test will suppress your own function. Any studies / medical...
