Studies that did not test the peptide alone2

In this study, Teriparatide (PTH 1-34) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Teriparatide (PTH 1-34).

    In severe osteoporosis, lumbar BMD changes explained 83% or 66% of the teriparatide treatment effect, depending on method.
