I restarted ADT with Eligard on August 31 2020 when my PSA was 0.453 and Testosterone 147. Today my PSA is 0.266 and Testosterone < 20. When I started Lupron + Casodex in November 2018 my PSA was 4.48, which dropped to 0.17 in just three months. This time, why the rate of PSA drop is much slower?
During ADT break my PSA increased rapidly from 0.07 to 0.453 while T increased to 147 over a period of 9 months.
