@rjd , you are responding to a post that is nine months old, so I'm not sure that person will even see it. My experience with Tymlos has been great. I've been on it for almost a year, and gained 15% bone density in my spine. My overall T-score went from -3.0 to -2.0, which is osteopenia instead of osteoporosis. I plan to stay on it for another six months, at which time my doctor and I will discuss next steps (either six more months, or start Reclast or Fosamax.)
