Hi Ning,
I can't give you advice but I can share my experience with two years of forteo. I had no noticeable side effects. The shots were very simple and not really painful at all. I had modest gains too. Have you taken any osteoporosis meds before? What is your greatest fear? Of course our bodies are all different. Just know you are in good company on this osteoporosis path and there is great wisdom here. Good luck to you.
