I finished my 12 months of Evenity which seemed necessary due to my severe osteoporosis. I got a 17% increase in my spine and hips made some improvement. I am now on Fosamax, lifting weights, gettign most calcium from food and doing a series of sensible spine exercises. I think the Evenity was worth it and honestly I never endured any bad side effects. Just hoping the fosamax will help keep the results. Could someone explain what P1Np is? I will have my labs soon.
