I tried every way to restart before hopping on TRT and I've run HCG along TRT for fertility reason and backfilling the pathways. I can guarantee you that there are few men that are able to run the compound for a long time without getting sides. I hope you will be one, but I never met anyone getting well on HCG monotherapy.
HCG offset the ratio between testosterone to E2 in favor of the latter, hence the reason why many have sides on it.
If you give your body bio-identical T, it knows how to handle it and how to aromatise it and 5-a reduce it, unless you have genetic aromatase or 5-ar deficiency, which is pretty rare.
PFS is a complete different story. It's not a lack of androgens, that's called hypogonadism (primary, secondary or tertiary) and that's why I got well when I introduced back the androgens in my body. It's not really well understood yet, but we could talk about PFS when there's an induced and permanent 5-ar deficiency or an induced androgen resistance, that weren't there before the use of 5-ar inhibitors.
The vast majority of people on propecia help didn't get a proper TRT protocol and used AIs with their exogenous T, hence why they're there complaining about their alleged PFS.
