Sue, consider running your numbers thru AI copilot, if you feel comfortable with that. I put in what you posted and the AI felt based on NIH information that:
The shift from her previous markers (P1NP 147, CTX 654) to her current ones (P1NP 38, CTX 371) reveals a significant transition in her bone metabolism. This typically occurs when moving from an anabolic (building) phase to a maintenance phase.

But you will be able to give copilot more information and ask questions of it about what you are taking and how it is affecting you.
Then you could run this past your doctors.
