While your initial jump of CTX is noticeable, I felt it doesn’t warrant reading too much into it, simply because jogging became a variable here. During initial phase of forteo treatment, increase in CTX is not a characteristic of the drug. When the time comes that you see a jump in P1NP reading, then you know you are in anabolic window. Yours may just be delayed a few months when compared with the statistics in clinical trials.

There must be a mastermind behind your therapy planning and careful monitoring, for few ppl had baseline and serial timed testings during anabolic therapy.
