If you aren't having trouble peeing, why not stop all meds (other than ED protective meds) and see what happens.
I have no idea how long pygeum has a residual effect for, or what its PSA-lowering effect has been for you. I'm sure everyone is different. I think you want to understand the true PSA pattern based on your SBRT treatment. Why cloud the issue? In the long run it won't matter. Did Meier recommend pygeum?
