Published research

What the research covers

Short summaries of peer-reviewed literature on each component. Findings come from laboratory and animal models and are shown for research reference only.

  • GHK-Cu01 / 04

    Skin-cell gene expression

    Reviews by Pickart and colleagues summarise gene-expression data in which GHK was associated with changes across many genes linked to tissue remodelling and antioxidant pathways.

  • TB-500 · Tβ402 / 04

    Cell migration & wound models

    In a rat full-thickness wound model, thymosin β4 was reported to increase re-epithelialisation and cell migration. Later reviews describe it as a multi-functional actin-binding peptide.

  • BPC-15703 / 04

    Tendon & blood-vessel models

    In cultured rat tendon fibroblasts, BPC-157 was reported to increase outgrowth, survival and migration. Endothelial-cell and rodent work associated it with VEGFR2 activation.

  • KPV04 / 04

    Intestinal inflammation models

    In intestinal epithelial cells and mouse colitis models, KPV was reported to be taken up through the PepT1 transporter and to reduce inflammatory signalling.
