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, Dihexa 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 Dihexa.

    Summary
    In models of cognitive deficit, eight of nine studies found Ang IV and its analogs (Nle1-Ang IV, dihexa, LVV-hemorphin-7) improved performance on spatial working memory and passive avoidance tasks.
