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

Studies that did not test the peptide alone1

In this study, Oxytocin was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Oxytocin.

  1. 01LabNot a test of Oxytocin aloneIn vitro (cell-free)Activity measurement

    YM471, a vasopressin V1A/V2 antagonist, bound rat oxytocin receptors with a Ki of 31.0 nM, much lower affinity than for V1A and V2 receptors.

    In plain wordsIn lab tests, a vasopressin-blocking compound bound oxytocin receptors much more weakly than vasopressin receptors.
