I'm 25 and I did a cycle of sust 350 last year. I took nolva and clomid for my PCT. a while after I started feeling like shit so I went to thr dr and they says my test level was low. He started me on a shot once a week every other week till I had 6 shots. I got my blood work done again and the dr said it was back above 700 but I still have now sex drive... What can be wrong
