in fibroblast culture models it stimulates collagen, elastin, and glycosaminoglycan synthesis at picomolar to nanomolar concentrations (10 to 10 M), and modulates metalloproteinase (MMP-1, MMP-2, MMP-9) activity and their inhibitors (TIMP-1, TIMP-2), functioning as a general regulator of extracellular matrix remodeling ( Mechanistic research establishes that GHK activates TGF- and integrin 1 pathways during tissue repair, attracts immune and endothelial cells to wound sites, and restores gene expression patterns toward a healthier fibroblast phenotype in models of aging and radiation damage ( A 2018 review in IJMS characterizes its role in collagen production, nerve outgrowth stimulation, and dermal stem cell marker expression ( For Research Use Only
When side effects do occur, they are typically mild and may include temporary redness, itching, or sensitivity at the application or injection site
