@lurawilson, thanks for sharing this info. I’ve always wondered about using HRT along with a PTH analog. There was a clinical study for teriparatide combined with HRT that showed a positive outcome, though 40mcg teriparatide - doubled the standard dose 20mcg found in Forteo - was used in the study.

Occasionally we hear anecdotal accounts of using the combo with good bmd gains, but your bone markers are offering a rare look into this less-studied combination. To me, even though the two agents involved here may have a 'tug of war' with opposing effects, your 3-mo readings were clearly favorable, with the P1NP percent-increase outpacing CTX. That initial lead might just be enough to result in a positive bmd outcome. Fingers crossed!
