I'm 21 and did a cycle of sustaplex 325 for a month. Didn't use anything for a post cycle. It was my first time using and I obviously didn't do enough research. I know stupid. Iv been off it now for about 8 months and have been having difficulty maintaining an erection or even obtaining one. Also have noticed testi shrinkage. Anything I can do to fix it. Or am I screwed. Any advice would be greatly appreciated.
