Bone turnover markers (CTX and P1NP): do you have a baseline?

Mayblin, thanks for looking at the bone markers.
I ran five miles just prior to my labs which were at 7am. Probably raising both numbers. Other variables were controlled.
My base numbers look kind of good to me. Can you speculate?

Your baseline line sure looked “fine”. The effect on exercising on btms are still not conclusive yet. There was a small study in which it showed jogging (aerobic exercise) might decrease CTX up to 4 hours and increase P1NP transiently. However this seems age and sex dependent while other studies were not reflecting this conclusion. If you stopped jogging for your subsequent testings, then comparison won’t be under same consistency.

The more intersting presentation is your two readings following baseline. There were no obvious or significant P1NP increases as expected. Had you experienced bad side effects or sickness that made you skipping doses? Anything unusual during first few months after commencing forteo?
