GHK-CU 50mg
This 50mg vial is the half-size GHK-Cu listing, alongside the 100mg. GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. Plasma GHK levels decline from approximately 200 ng/mL at age 20 to 80 ng/mL by age 60. Originally identified by Dr. Loren Pickart in 1973 as a factor in human plasma that promoted hepatocyte function, GHK has since been shown to influence the expression of over 4,000 human genes in gene array studies. This listing contains 50mg of lyophilized material. Supplied strictly for in-vitro research and laboratory use only. Not for human or animal use.

Mechanism of Action
GHK-Cu chelates copper(II) ions with high affinity, delivering bioavailable copper to tissues where it is required for enzymatic activity (lysyl oxidase, superoxide dismutase, cytochrome c oxidase). The peptide activates tissue-repair cascades including collagen I/III synthesis, glycosaminoglycan accumulation, and decorin expression. Zhou et al. (2017) studied GHK and TGF-β1/Smad signaling in mice with bleomycin-induced lung injury.
