Thats called HRT. This is what test and hcg is normally for. You want to keep the dose low though. Not cycle dosing. More like 200mg every week. Then cycle up for say, 8 wks higher, then back down to HRT for 8-10 wks. HCG will keep teste size normal, around 500iu every 3 days is fine. You will also want to use adex for estogen control. Everyone is different, but you might want to start with about .5mg 2x wk on that dosing of test. With properly dosed adex, there is no need for nolva or clomid to control estrogen
