GHK, a tripeptide consisting of glycyl-histidyl-lysine in its
amino acid sequence, is naturally present in human
plasma, saliva, and urine. Its concentration in plasma
typically measures around 200 ng/mL at the age of 20,
diminishing to approximately 80 ng/mL by the age of 60.
This reduction in GHK levels aligns with the observable
decline in an organism’s regenerative capabilities.
Extensive scientific investigations have unveiled GHK’s
potential role in aiding wound healing, managing infections,
promoting hair growth, addressing aspects of cancer,
supporting cognitive health, and exploring cosmetic
applications for facial enhancement.
