In laboratory research, GHK-Cu is utilized in gene expression profiling experiments (documented effects on 4,000+ human genes), extracellular matrix research gene expression studies (collagen I, III, IV), matrix metalloproteinase (MMP-1, MMP-2, MMP-9) and TIMP regulation assays, glycosaminoglycan deposition measurements, decorin and integrin expression studies, superoxide dismutase (SOD) activity assays, and investigations of VEGF, FGF-2 expression modulation
Even meat-eaters can experience deficiency due to poor absorption, which often relies on a stomach-produced protein called intrinsic factor
A summary of such studies is shown in Table 2
As you may have noticed, the positive effects that occur when glutathione levels are sufficient in the body can be quite significant
