My situation is almost identical to yours, and I’m about to start a bio-similar drug to Forteo. I am 65, fit, athletic and a downhill skier with a -3.1 lumbar spine and a -2.7 femoral neck. My endocrinologist recommended Prolia until she found out I had no intention of stopping to ski double black diamonds in the mountains. Since I haven’t fractured anything, I don’t qualify for Forteo in Canada (that was her anabolic of choice for me as she said we aren’t sure if Evenity causes cardiovascular problems yet and I have a family history plus an irregular heartbeat).

Osnuvo is a bio-similar teriparatide, and I’m told it is virtually the same as Forteo, but a fraction of the cost. I’m still out west skiing and heading home this week. I plan to look at the profile of the drug compared to Forteo more closely, as well as talk to their patient service that my endocrinologist signed me up for. If I’m satisfied I’ll start the first week in April. My endocrinologist said the dose is fine for me (125 lbs), as they also give it to children.
