The decline is gradual rather than sudden, which researchers note is consistent with a compound that functions as an ongoing signaling factor in tissue maintenance rather than one tied to a single life stage or event
In wound and tissue contexts, GHK-Cu is studied for its involvement in normal healing processes, including extracellular matrix remodeling (the skins structural scaffold made largely of collagen and elastin)
Further research is needed to elucidate the circumstances, specific molecular targets, other enzymes involved in the signaling process, and to map the involvement of GSH in redox signaling pathways ( An emerging area of research is that of immune memory in the brain (Neher and Cunningham, 2019)
GHK-Cu, or Glycyl-L-Histidyl-L-Lysine-Copper, is a naturally occurring copper peptide that has garnered significant attention in the fields of dermatology and regenerative medicine
(6) Note that low levels of glutathione have been associated with higher risks of hepatitis, type 2 diabetes, Parkinsons disease, and cancer
