It takes 2 to 3 months for most people to get their PSA down to undetectable. Your testosterone doesn’t go up if you are castrate resistant, more likely it just hasn’t gone down all the way, yet. If castrate resistant your PSA goes up even though you’re on ADT. Give it some time.

If your PSA does continue to rise while on ADT then you need an ARSI like Zytiga or a Lutamide, That can get your PSA down when ADT alone won’t do it.
