Hi @pauladiamante, when was the CTX result (285) taken? If that was your baseline before any treatment, then your bone resorption is on the lower side. But if it was measured while you're on Evenity, that would sense since evenity suppresses bone resorption, so this CTX reading is expected.

I've read that for people with very low baseline bone turnover, some endos may choose to use a lower dose (I've come across 1/2 dose of fosamax - 35mg/wkly) of bisphosphonate to help "lock-in" the bmd gains after an anabolic treatment. So basically some form of antiresorptive therapy is still needed after an anabolic even if your true baseline CTX is very low. In this case, you could taper off the antiresorptive therapy over time with careful monitoring.

That said, oral form of bisphosphonates such as fosamax or actonel are usually easier to adjust in terms of dosing. Smaller dose of iv zolendronate is an alternative. Personally, I don't see how you could taper off Prolia without transitioning to a bisphosphonate, unless you've only had one dose. Even then, your resorption ( as indicated by CTX) is likely to go up once that dose wears off, then returns to your baseline after a period of time. You may or maynot have some degree of bone loss during this period.
