GHK-Cu Peptide: Benefits, Uses, and What the Research Shows

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide found in human plasma, saliva, and urine. It declines with age — significantly so — and this decline correlates with reduced tissue repair capacity, skin quality, and immune function. It has one of the most extensive research bases of any naturally occurring peptide, with
