Sounds like you are in the same position I was. I called it a booster round because I took Forteo in 2016 for two years and it was recommended again now, as my numbers had slight decline, but are baseline low to start with. So I am currently doing the bio identical brand Teriparatide because it is cheaper, but basically the same thing (so I'm told). They only prescribed it for 18 months though. I did Raloxifene as maintenance after Forteo and will return to that. Did you do anything after Forteo the first time? I am very reluctant to do Evenity as it is made by Prolia and I had severe reaction to that. Also, from what I am reading, it does not hold its gains as well as Forteo.
