Testosterone injections only work for about 50-60% of people from studies I have read about using BAT. 40-50% of them have their PSA start rising too much right away due to it feeding the prostate cancer. People with serious castrate resistant issues are more likely to get benefit as it kills off those cells.

The thing is, there’s a lot of controversy about this. No specific reoccurrence rates are seen with different groups of patients.

Even people who are castrate resistant have many cells that are not castrate resistant and can immediately react to additional testosterone, by growing.
