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

Acute complete depletion may rapidly amplify oxidative stress and cell injury, whereas more gradual depletion appears to allow for more selective redox remodeling without overwhelming stress responses, although further studies including comprehensive transcriptomic and epigenomic analyses will be necessary to dissect the differential regulatory networks altered by different modes of GSH depletion

also present is the low-energy TA S4 conformer

It is made up of three essential amino acids: cysteine, glycine, and glutamic acid
