    Summary
    In the spine, integral vBMD and strength increased substantially after 2 years daily and 4 years cyclic TPTD, with no significant differences (vBMD +12 % vs +11 %, respectively, p = 0.70; spine strength +21 % vs +16 %, respectively, p = 0.35).

Studies that did not test the peptide alone1

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).
