can glutathione production increase cancer growth Catabolism of extracellular supplies cysteine to support tumours Glutathione-Dependent Pathways in Cancer Cells
Description
It's well studied for skin, but nobody has tested whether restoring GHK-Cu actually slows aging anywhere else

As we found evolutionary conservation of many known S -glutathionylation sites on plastid proteins, including non-catalytic cysteines, we conclude that protein S -glutathionylation in plastids plays an important and yet under-investigated role in redox regulation and stress response
