@gravity3 my understanding is that going on a bisphosphonate after Evenity is to lock in gains and not so much treatment and maintaining those gains. The only other option is Prolia but that leads to a bisphosphonate anyway, when stopped. Prolia can work really well but you can also lose your gains when stopped. One option people here have suggested is to do Prolia just 2-3 times and then a bisphosphonate to get the boost in bone density from Prolia but minimize the risks from rebound when stopped.
