Research overview
GHK (glycyl-L-histidyl-L-lysine) is a tripeptide found in human plasma. Reported levels average about 200 ng/mL at age 20 and about 80 ng/mL by age 60; it binds copper with high affinity to form GHK-Cu 1.
Gene-expression studies of GHK are reviewed in 2, and topical formulation research in 3.
