Data were assessed using the Cochrane Risk of Bias Tool (ROB2), and statistical analyses were conducted with RevMan 5.3

What sets GHK-Cu apart in the research literature is scale: naturally occurring levels of the peptide in human plasma decline from roughly 200 ng/mL at age 20 to about 80 ng/mL by age 60, a drop researchers have used as a starting point for studying its potential connection to age-related changes in tissue repair
