check hospitals doing research on Prolia I believe Prolia injections are free as long a you are part of study on Prolia.All depends on what kind of specific you have before taking Prolia. Ask as many questions as. possible. All depends where you live In US check Mayo, University hospitals big institutions . Good Luck. I asked OSteo dr if he would give it to his wife and he said no, yet he was ready to prescribe to me. This gave me second thoughts and after I researched, thank you I will pass on Prolia.
