@rola please check that out with your doctor. I am gettijng different info from different providers, including McCormick. I watched Dr. Ben Leder's vido on Combinations and Sequencing and he mentioned cortical porosity with Forteo so I was concerned the same was true of Tymlos. My endo told me last night that this was a concern with Forteo, not Tymlos, but I hope you can make sure this is true.
