Today I read that femur neck only progresses 2.8% in the first 6 months and 7.5% if Evenity is done for the full 12 months. Surely this is from anti-resorptive action but the gain is much stronger than with Reclast (though values are extremely varied for Reclast among studies). So the idea of a boost over 3-4 months may mainly apply to the spine. Nevertheless studies are being done on Evenity for 6 months and Reclast for 6 months vs Evenity for 12 (followed by 12 months Reclast).

I saw 1) 6 months Evenity, 12 months Reclast, 6 months Evenity. 2) 6 months of each 3) 6 months Evenity, 12 months Reclast, 4) 12 months of each and 5) 6 months Evenity, 18 months on Reclast
