no idea bro. I only run 2 month cycles and i recover fine after time off. dunno if anyone on here has ever run tren 6 months like that to answer this question??? i think bloke has cruised on tren, maybe he will chime in later.
do you have any libido? how are your nuts? did they turn to raisins and then plump back after that pct you ran?
like RADAR said you are gonna have to run an aggressive PCT. i would run hcg, hmg, clomid, natty supps he listed... the works. heck you might even run all 3 together and throw the kitchen sink at the problem. and then do another sperm test to see if you are doing anything to rectify the problem.
your uro you are seeing is clueless on AAS 99% of the time, you need to see an endo who has knowledge of this situation. its gonna take a while but a strong PCT should speed things up. i wish you could just run tren for 6 months and then not be able to have kids, I think that would be much easier to do then have an operation LOL. unfortunately mother nature doesn't work like that.
