I’ve had a similar question. Intermittent ADT has proven superior to continuous. It is considered a good practice by many to come off of ADT, monitor Testosterone and PSA every three months to see how the PSA responds to the increasing Testosterone levels. At some PSA level imaging (PSMA PET/CT and maybe others) is done to identify problem areas and treat.
My problem is that after being off of Lupron for nearly a year, my Testosterone has not returned. If after a full year there is still no Testosterone, I plan to request a short period of TRT for the above reasons and to give my body a break.
