Results from this study4

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

Natural levels measured4

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 human pineal-gland tissue from men, HNp I positively correlated with endogenous oxytocin concentrations (rs 0.86).

    In plain wordsIn lab tests of male pineal tissue, HNp I was linked to higher levels of the body's own oxytocin.

    Summary
    HNp I correlated both with AVP (rs = 0.54 for men and 0.55 for women) and OT (rs = 0.86 for men and 0.57 for women) but not with AVT, while HNp II correlated with AVP (rs = 0.52 for men and 0.53 for women) and OT (rs = 0.92 for men and 0.50 for women) but not with AVT.

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