Results from this study2

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

Natural levels measured2

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
    Unlike the marked daily rhythm of oxytocin concentrations recently described in the CSF of the rhesus monkey, no daily rhythm of the peptide was evident in the CSF of either the cat or rat.
