HCG will suppress natural test production so I never used it for PCT but rather to keep the testes active while on cycle. I'd run like 1,500iu MWF every other week while cycling. Never used HMG, exemestane my anti E of choice on cycle, never used one in PCT. If I was going to use an AI for PCT I would use exemestane because it has no estrogen rebound like some other AIs do.
PCT was always 2 weeks 100mg clomid/40mg nolvadex then 2 weeks 50/20 never had any trouble with recovery, everything was functioning pretty well within 3 weeks of starting PCT. Now I'm on HRT. I don't think it was from the couple of cycles I ran, I'm just middle aged now and my test isn't what it used to be, also it just feels good, best anti depressant ever. I do like being on HRT and not having to worry about PCT at all, I can run an 8 week blast or a nice 16 week long run and coming off is a breeze, though I guess it is kind of like never coming off.
