From what I’ve read, a compression fracture can cause P1NP to rise. So, would Forteo. I do t think Forteo would raise CTX, not sure about fracture healing. From reading McCormick and listening to Lane Simpson, I think you want CTX to be 300-400. P1NP not on anabolic, 30-50, but it goes higher in anabolics as it should. My numbers aren’t terribly far from there and I still fractured. If you had lumbar fracture I highly recommend kyphoplasty. Helped with pain and quicker return to exercise.
