Mechanisms such as increasing cellular antioxidant enzymes, stabilizing membranes, supporting DNA and mitochondrial repair, and modulating inflammatory cytokines suggest that peptides target multiple pathways for more impact
The free tripeptide was first identified in human plasma in 1973 by Loren Pickart as a factor supporting cell proliferation in liver cell cultures, and the copper-binding role of the peptide was recognized shortly afterward as the molecular basis for many of the activities attributed to GHK
When evaluating research peptide products, understanding what peptide purity really means is essential
