    Cognition Peptides

    Peptides studied for potential cognitive enhancement and neuroprotection.

    Selank

    Medium Evidence

    A synthetic peptide analog of tuftsin studied for anxiolytic and nootropic properties.

    Semax

    Medium Evidence

    A synthetic peptide derived from ACTH, studied for cognitive enhancement and neuroprotective effects.

    Dihexa

    Low Evidence

    A hexapeptide analog studied for cognitive enhancement via hepatocyte growth factor pathway activation.

    Cerebrolysin

    Medium Evidence

    A porcine brain-derived peptide mixture approved in some countries for stroke recovery and neurodegenerative conditions.

    Pinealon

    Low Evidence

    A short bioregulatory peptide studied for neuroprotective effects and cognitive support in aging.

    P21

    Medium Evidence

    An 11-amino-acid CNTF-derived peptide studied for its ability to upregulate BDNF expression and promote neurogenesis in cognitive decline models.

    Klotho (Alpha-Klotho)

    Low Evidence

    A naturally occurring longevity hormone (secreted alpha-klotho) being studied for cognition and brain aging; a single low-dose injection improved memory in aged monkeys, and a first-in-human Phase 1 trial in older adults is underway.

    Davunetide

    Low Evidence

    An eight-amino-acid ADNP-derived peptide studied for microtubule stabilization, tau-related neuroprotection, and rare ADNP syndrome.
