GHK Basic 50mg Overview
GHK Basic 50mg from Peptide Science is the standard single-vial format of the uncomplexed glycyl-L-histidyl-L-lysine tripeptide, supplied as a lyophilised vial for in-vitro research where the free tripeptide is required rather than the copper-bound GHK-Cu form.
Compound Class and Mechanism
GHK is the naturally occurring tripeptide present in human plasma at concentrations that decline with age, originally characterised by Loren Pickart in the 1970s as a wound-healing-related growth-factor activity in plasma. The uncomplexed form is studied in cell-culture research separately from the copper-bound GHK-Cu, since the binding-affinity profiles at copper-dependent enzymes differ between the two forms.
