GHK-Cu dosing protocols frequently run for extended periods weeks to months because the tissue regeneration, skin research, and anti-aging biomarker effects develop slowly
In the second step, the homodimeric enzyme GS, a member of the ATP-grasp superfamily, rapidly catalyzes the binding of -glutamylcysteine with glycine, obtaining GSH (8, 9)
The tripeptide has high affinity for copper(II) ions, chelating them and facilitating cellular uptake without the oxidative risk of free copper
