Results from this study2

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

Studies that did not test the peptide alone2

In this study, Vasoactive intestinal peptide (VIP, aviptadil) 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 Vasoactive intestinal peptide (VIP, aviptadil).

    Summary
    The primary structure of VIP from both species was the same: His-Ser-Asp-Ala-Ile-Phe-Thr-Asp-Asn-Tyr10- Ser-Arg-Phe-Arg-Lys-Gln-Met-Ala-Val-Lys20-Lys-Tyr-Leu-Asn-Ser-Val- Leu-Thr.
