ghk-cu peptide benefits for skin repair Rejuvenation Copper Peptide GHK-Cu Beef Tallow:

Published preclinical and in vitro research has examined its interaction with extracellular matrix remodelling, broad gene-expression modulation, antioxidant and anti-inflammatory pathways, and copper-coordination chemistry in cultured fibroblasts and animal wound models

And it is secreted out of the cells in the precursor form (pro-HGF) and also activated by the proteolytic cleavage at the Arg-Val site (Naka et al., 1992

GHK-Cu differs from other signal peptides (Matrixyl, acetyl hexapeptide-8, palmitoyl tripeptides) in its copper-coordinated mechanism and broad gene-expression effects

MOTS-c has the most direct disc-specific evidence, with rat studies showing preserved disc height and reduced degeneration scores
