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.

  1. 01AnimalEndogenous levelOther designMechanism

    Acid extracts of ovaries from several mammalian and nonmammalian species contained oxytocin-like immunoreactivity by radioimmunoassay.

    In plain wordsIn ovary tissue from several animal species, lab tests found material that reacts like the body's own oxytocin.
