My PSA doubled in each of the first two months, but I had associated liver issues. At the end of the third month, it fell a level below the point at which I started it, but liver issues made us stop it.
So for me, impact was after three full months.
The Oncologist had warned me that PSA could at least go up, and maybe very substantially, in the first few months. He was right in my case.
