Each row summarizes the impact of the evidence on treatment
GHK-Cu stimulates fibroblasts to produce collagen, elastin, and glycosaminoglycans the structural proteins that keep skin firm and tissue elastic
Endotoxin contamination, heavy metal contamination, incorrect peptide sequence, and unknown formulation components are documented risks of non-pharmaceutical-grade manufacturing
Its antioxidant properties are also well-documented, showing a capacity to mitigate oxidative stressa known contributor to cellular aging
We've included GHK-Cu (copper peptide complex) because it can support the skin's natural collagen pathways
