GHK-Cu, or glycyl-L-histidyl-L-lysine copper complex, is a naturally occurring copper peptide studied for collagen-related pathways, tissue remodeling, antioxidant defense, and skin repair [7] [8]

This mechanism is key to understanding the 5-Amino-1MQ before and after effects

GHK as a copper-binding peptide GHK binds copper(II) through coordination by the N-terminal amino group of glycine, the imidazole nitrogen of histidine, and the deprotonated amide nitrogen of the Gly-His peptide bond, forming a stable square-planar (or square-pyramidal) complex

During treatment, blood tests and neurological examinations must be performed
