Results from this study1

No result from this study comes from a test of the peptide.

Natural levels measured1

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    Summary · context
    A prospective observational study was conducted in twenty Japanese healthy adults (mean age, 58.4 years).
    Summary · context
    Five salivary stress biomarkers (cortisol, α-amylase, S-IgA, chromogranin A, and oxytocin) were measured to quantify the stress levels before and after each HA.

    This result measures the body's own Oxytocin. Nobody was given the peptide. It is not evidence about taking it.
