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.

    In Brattleboro, Long-Evans and Wistar rats, oxytocin output into hypophysial portal blood did not differ significantly between strains.

    In plain wordsIn rats, the body's own oxytocin released into pituitary portal blood was not significantly different between the three strains.

    Summary · context
    The purpose of this study was to compare the control of adrenocorticotropin (ACTH) and corticosterone secretion in homozygous Brattleboro rats with their syngeneic controls, Long-Evans rats, and with rats of the Wistar strain.

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