Key publications: 'Stimulation of collagen synthesis in fibroblast cultures by GHK-Cu' (1988, FEBS Letters), 'In vivo stimulation of connective tissue accumulation by GHK-Cu' (1993), 'GHK-Cu stimulates matrix metalloproteinase-2 expression' (2000)
For years, the prevailing wisdom in the wellness community was that oral glutathione was largely ineffective because the digestive system would break it down before it could ever reach the bloodstream
A brief warm sensation or flushing can also occur
Promotes Collagen and Extracellular Matrix Production GHK-Cu isnt just about hair
While still highly significant versus baseline, the high-dose group actually produced fewer new hairs than the low-dose group consistent with the biphasic dose-response seen in the 2007 Pyo laboratory study where higher copper peptide concentrations inhibited rather than stimulated growth
Injecting unregulated GHK-Cu purchased online introduces risks of heavy metal contamination and copper toxicity that far outweigh the theoretical benefits
