THanks @colleenyoung. @hollygs this article states that markers (all markers?) increase on Forteo and Tymlos. This is what I usually see. That other article that I posted above is the first time I have seen something more complex. Interesting that this article says bone markers are not useful when on anabolics since so many here on the forum are using them with Forteo and Tymlos to see if they are working, (I do have kidney disease so I don't use the CTX...) So confusing! Here is an excerpt:

"BTMs are not of much help in monitoring people on anabolic therapy. Anabolic therapies — such as teriparatide (Forteo), abaloparatide (Tymlos) and romosozumab (Evenity) — work by stimulating bone formation, which leads to increases in bone mass and density. Since new bone is being built, the markers are expected to increase and are not helpful in the decision-making process. There is also no role for monitoring after completion of anabolic treatment, as all these agents should be followed by treatment with anti-resorptive drugs without a pause in treatment."
