Same. Before I started Boniva, they did the bone turnover test and never explained it to me. It was low which means my rate of bone loss was slow) and they still put me on Boniva. I only took Boniva for 2 years. I am going the natural route from now on. Osteostrong could not explain it to me and on line you cannot find any reasonable explanation. For CTX any number over 60 is considered bone turnover loss. Mine has been at 35 for the last 2 years and I am on HRT. 100% agree no one can explain results.

That statement actually is not true at all. CTX is highly individual. 60 may well be the red line for you, but it's not for others. It has to be evaluated in conjunction with P1NP.

My CTX has never been lower than 150, and I've gained 15% bone density in the past year. My P1NP has never been higher than 80, while others have had much higher numbers when on medication.
