44yrs old, I put myself on TRT, 200mgs of test cyp a week, I hated coming off cycle, please correct me if I'm wrong, but I got tired of the libido shut down, ED an loosing gains, some of the research I've done says with TRT I wouldn't have to worry about that, but noticed the 1st of the week that really didn't care if I had sex with wife & my dick getting half hard other than that I'm feeling great, I'm 4 weeks off my last cycle, I started my TRT the following week after my last injection..... What's up with loss libido & half ass erections? What am I missing? Thanks for any input an advice,,,,,
