Is ADT ever used at reduced dosage to moderate side effects?

I really never see anybody saying their PSA is zero. Occasionally, you will see < .001 But that is not very common.
There isn’t really a way to reduce ADT dosage. The shots last a certain amount of time and give the same amount of the drug Each day. You could alternate Orgovyx, But you probably would end up with your testosterone down really low no matter what.
If your purposes is to not have your testosterone go down so low, you could get on a Lutamide Drug like Darolutamide Which can work even if testosterone is high.
After radiation, the PSA doesn’t go down immediately for a lot of people. And for most it doesn’t even go down to < .001 . Mine did go down to < .1 3.5 months after radiation, but I never had an ultra sensitive test to tell me if it was any lower. I do know that some people have taken up to three years before their PSA hit rock bottom after radiation.
ADT usage is based on other things. How high is the PSA?, Are there other aggressive features in the biopsy? Has there been a reoccurrence that requires radiation? Has the cancer spread beyond the prostate?
If someone had a very aggressive case of prostate cancer, they would generally put them on ADT before the PSA got down to the lowest level after radiation. Some people say no to ADT.

@jeffmarc I would presume a lower dosage is possible, shots or pills.
My guess would be that this is not an unreasonable thing to do but that frequent monitoring and dose adjustment would be required and no provider wants to do that much work.
But it could at least be evaluated in studies.
(heck, start with rats, or whatever they use!)
I see ADT has been used for decades or longer, depending on what you count, and in all that time, no studies?
It might fail, but living with milder side-effects might be a winner at least for some, of course it depends on all the metrics I see people talking about and then actual monitoring and adjustment for each specific case.
My questions are colored by my experiences with other drugs for other conditions where the standard dosing has often turned out to be too high for me or the optional higher dosing has increased side-effects but not been any more effective.
I do not see how a PSA < 0.001 is even possible since men with no tentacles will be higher than < 0.1 since there are other organs that produce small amounts of testosterone.

@jeffmarc “ You could alternate Orgovyx, But you probably would end up with your testosterone down really low no matter what.”
If the end result (low testosterone) was the same, could you reason that toxicity might be reduced?
Has anyone ever just taken the pill every second day? I presume some people have but haven’t heard any reporting on it.
