I recommend a test for serum testosterone (T). This will produce
evidence whether the ADT is succeeding. On ADT, the T should be at
castrate level, < 20 ng/dL. See,

Strum and other knowledgeable med oncs recommend at least one full year
of UD (=/< 0.05 ng/mL) PSAs while on ADT before moving to an off-phase.
When to restart is a vexed question. Some say 2.0 ng/mL above nadir.
Others have other criteria.
