@rjkesal123, i haven't used any bisphosphonates but have read quite a bit about them. It does look like alendronate didn't bring your bone turnover (as indicated by marker CTX) down as much as typically expected. Switching to risedronate (Actonel) is interesting as it tends to be a bit less potent than alendronate at suppressing bone turnover.

Hope you have better luck with Actonel!
