  • AHK

    Tripeptide Ala-His-Lys; no published study tests the free peptide. Its copper complex AHK-Cu has ex vivo human hair follicle data and its own catalog entry.

    Evidence: Anecdotal

  • AHK-Cu (Copper Peptide)

    Copper(II) complex of the tripeptide Ala-His-Lys; one ex vivo study found it lengthened human hair follicles in organ culture and raised dermal papilla cell proliferation.

    Evidence: Preclinical

  • GHK-Cu

    Copper complex of the tripeptide Gly-His-Lys, isolated from human plasma in 1973; raises collagen synthesis in cell and rat studies, with mixed results in small topical human trials.

    Evidence: Preclinical

  • GHK-Cu Capsule

    Oral capsule formulation of the copper tripeptide GHK-Cu; oral absorption and systemic efficacy are unestablished, with human evidence limited to topical GHK-Cu.

    Evidence: Anecdotal

  • Pal-AHK

    Palmitoylated, amidated tripeptide Ala-His-Lys, known only from the EU cosmetic ingredient register (Palmitoyl Tripeptide-52 Amide); no published study of this compound exists.

    Evidence: Anecdotal

  • PTD-DBM

    Cell-permeable peptide that blocks the CXXC5-Dishevelled interaction to de-repress Wnt/beta-catenin signaling; studied topically in mice for hair regrowth and wound healing.

    Evidence: Preclinical
