This might not be much of a help but i'll shout it anyway:
When i first took finesteride i started with 1mg every day, had to quit due to sides 3.5 months later...
Started finesteride 1mg one year after eod, had to quit due to sides about 5 months later...
I believe that taking it eod can reduce sides...Not enough for me unfortunatly...
My sides were mainly testicular pain and a little brain fog...
Both times i quit, i fully recovered from it...thankfully...Many are still struggling with pfs
