Bro, if you want to truly restart, you eventually need to get off of anything that suppresses natural LH and FSH production. This absolutely includes hcg and other similar hormones. Being on 5000 iu of hcg a week is going to suppress your natural LH. Btw, why aren't you testing for LH on your labs?
Either way, all serms will help in getting the pituitary to start producing LH. Tamox, torem, ralox, clomid, enclomid, etc. All will work. It just depends on which one you feel the least sides, that's all. And tbh, I know 2 weeks isn't a lot, but 2 weeks on nothing but a serm should start in raising your natural LH production. This is why you should be testing for LH so you can see if it's moving up, even if it's moving up a mm a day, you'll be able to see it. If there is very little or almost zero movement of LH in a month, imo you should start considering you are primary hypo gonadal which means you aren't able to produce LH and need to take either hcg or test for trt (or gnrh for that matter, but have no idea if that is ever done).
