GHK-Cu differs from other signal peptides (Matrixyl, acetyl hexapeptide-8, palmitoyl tripeptides) in its copper-coordinated mechanism and broad gene-expression effects
downregulation of destructive MMPs (MMP-1, MMP-3) Antioxidant systems: Increased expression of glutathione reductase, thioredoxin reductase, and superoxide dismutase isoformseffects documented in Pickarts 2015 study (PMID: 28386432) Angiogenesis control: Modulation of VEGF and angiopoietin pathways, explaining observed wound-healing acceleration in diabetic ulcer models Neuronal protection: Upregulation of neuronal survival factors and downregulation of pro-apoptotic proteins in hippocampal neuron culturesa neuroprotective dimension entirely absent from UK marketing materials This gene-regulatory breadth means clinical applications extend far beyond dermal cosmesis
Another study found 300mg (100mg three times a day) of cats claw improved the energy levels of terminal cancer patients without affecting their inflammation.49 Ultimately, theres still a lot of research to be done to understand how cats claw extract works (or doesnt)
And in the first randomized trial (STOP-Vanc, 2026) the swab alone did not cut vancomycin days without an active prompt to stop
This makes it an ideal route for peptide delivery
