Has anyone gone off hormone therapy (ADT) after radiation?

My husband has completed 5 weeks of radiation and 4 months of hormone therapy, 3.5 months ADT. His PSA is less than .2 The doctor seems pleased with the PSA and is hoping that it will soon be undetectable. If he gets to that point, can he take a break from hormone therapy and ADT. He gets his next hormone shot in October. I am hoping he will get Orgovyx , instead of the Elegard. I hate that the hormone therapy has impacted his muscle and bone density. He looks smaller to me. He is trying to do weights and he is signed up for a weight room next month, when we return home from our summer holiday. I would appreciate any input
