I have read a few people on here saying that it is pointless to use HCG while on trt. I am on TRT at 200mg/week of Test C, and my doctor is giving me 500 iu 2x/week of HCG. The reason why I asked for the HCG is to preserve fertility until I am ready to have children several years from now, and also to maintain testicular size. It does do these things, correct? Also, I have been having very bad insomnia since starting the HCG. Could it be the cause?
