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.

    Immunocytochemistry identified a ventral subpopulation of VIP-containing neurons, distinct from dorsal vasopressin-containing neurons, in the human suprachiasmatic region.

    In plain wordsIn the human brain, the body's own VIP was found in a separate group of nerve cells in the suprachiasmatic region.

    Summary
    Immunocytochemical identification of distinct ventral vasoactive intestinal polypeptide (VIP) containing and dorsal vasopressin containing neuronal subpopulations in the human suprachiasmatic region

    This result measures the body's own Vasoactive intestinal peptide (VIP, aviptadil). Nobody was given the peptide. It is not evidence about taking it.
