Bro m going through a very tricky situation, if u cn help me. I ws about to start trt but before that startd using hcg fr sumtym to restore my fertility as i wanted to get my sperm frozen before getting onto trt. Hcg worked very well for me, libido was awesome, erections were great evn though i was taking a bit higher dose at 1000 iu eod, thinking i m taking it temporarely, and will never need it back once on trt (i red bout leydig cells decensatization but the lower dose was just not working). But the problem is once i started taking testosterone 50 mg twice a week first thn increased the dose to 100 mg twice per week, it just didnt work, lost all my libido (it literally fell to zero), no erection. So hcg alone is working gud but testosterone is not. Cant understand why. If u can help.
