BAT is a different situation - that's for someone who still needs hormone therapy to suppress incurable cancer.
By you saying you'd finished ADT, and seemingly had a treatment with curative intent, I was presuming you don't need further hormone therapy or any treatment.
We had one person here on lifelong hormone therapy who persuaded his oncologist to let him try BAT, but on his first Testosterone cycle, the cancer went rampant and took his life. I've never come across anyone else who's tried it. I rather suspect that to be effective, you probably need to start BAT before the cancer gets castrate resistant, but that seems like one hell of a risk if you are currently on ADT which seems to be working well.
