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
    On the basis of individual variability in sucrose preference, test rats were divided into anhedonic and hedonic groups.

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