been on trt for three years now, I do injections once a week and use ai when needed. I have never used hcg before just wondering why anyone that was done having kids would want to take another chemical and inject another chemical in there body if the didnt have to. Its a pain in the ass as it is just worrying about taking the testosterone for the rest of my life and pinning my ass once a week is a pain in the ass as it is. So unless you think your going to have kids still and want bigger balls then be my guess, my dr said thats the only reason i would need it, no thanks. Keep it simple guys less is sometimes best.
