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?

mayblin, I was ok with the small P1NP increase, but maybe not the CTX jump. I did carefully take calcium and d3 before the injection. And have read that blood calcium levels reduce PTH in blood and that d3 might be a cause for blunted response to teriparatide. Thanks.
