The review characterizes GHK-Cu as a broad-spectrum regenerative signal that modulates thousands of genes relevant to wound healing and anti-aging, providing the genomic basis for its observed clinical effects
Nerve health: These benefits are particularly important for people with diabetes or other conditions that affect nerve function

Figure 1: Folate metabolism starts with polyglutamate folates (a form of Vitamin B9), which are broken down by the enzyme dihydrofolate reductase (DHFR) into dihydrofolate and then tetrahydrofolate (THF)
