Tissue Repair and Regeneration The actions of the GHK-Cu peptide include modulating 31.2% of human genes (4,192 genes) with 50% expression changes[5]
This is not true
The primary molecular actions relevant to skin are: modulation of TGF- signaling (upregulating TGF-1 for collagen I/III synthesis while suppressing TGF-2 to prevent scarring), decorin upregulation for orderly collagen fibril assembly, MMP suppression paired with TIMP upregulation to preserve ECM integrity, and copper-dependent lysyl oxidase activation for collagen crosslinking
Also, excessive intake of folic acid can lead to the unmetabolized folic acid accumulating in the bloodstream, a topic which has raised concerns

When NNMT is too active, it consumes our precious supply of NAD+ (nicotinamide adenine dinucleotide), a coenzyme that is absolutely essential for cellular energy production and DNA repair
