good explanation about 19 nor's reducing DHN.. however i can point to thousands of threads where guys ran test higher than deca and still had problems. me included. running test doesn't cure everything but it can damn sure make things worse.
also lowering DHT doesn't necessarily give you erections.. if that was true we could just take proviron, masteron, primo etc and call it a day. be careful about listening to internet parroting of advice, it can hurt you
the bottom line is there is no one answer to what causes deca dick... we really don't know. what you read on that other forum is just a theory, but i will mantain that just cause you stack test with it that it won't necessarily cure your issue.. most especially when you come off cycle.. this is why i called that 'bro science' .. it is internet theories by guys who peddle it as fact with no evidence to back it up .. I believe 'deca dick' is caused by a combination of things, but I also believe 'deca dick' isn't just exclusive to deca or any nandrolone.. it can happen on any cycle, and yes even test. but my theory isn't bro science cause I can point you to hundreds of threads from real life experiences while your friend on that other site ignores the threads that show his theory isn't always the case
taking caber while on will most definately help no matter what as lowering prolactin fools the brain into not being satisfied from sex.. that feeling you get when you blow your load where you want to get away from the girl as fast as possible and go watch the game gets lessened.
bottom line is I choose not to run nandrolones period. been there and done that. the recovery from 'deca' makes it counter productive to goals. its a long and stubborn ester and if you want to go that route atleast choose NPP instead atleast with those of us who choose to cycle and not just stay on
