@gretch19 and @255anny I have been told that the rise in P1NP is much shorter than expected with Evenity. Dr. Ben Leder's video on You Tube entitled "Combining and Sequential Approaches to Osteoporosis" has a graph that shows it rise in the first week and then rapidly go down.

I had a P1NP done at one month (and a CTX) and mine was the same as before Evenity - in the low 50's. My doctor told me I had missed the rise in P1NP because I did it at the end of the month.

One of my endos said they really don't fully understand how Evenity works and originally the expectation was that it would be a bone builder throughout, which proved not to be true- it becomes anti-resorptive which is evidenced with a lower CTX.
