Peptide Specifications

Molecular Structure and Biological Activity

GHK-Cu consists of the naturally occurring tripeptide Glycine-Histidine-Lysine complexed with a copper ion, forming a highly bioactive peptide complex involved in numerous physiological processes. Copper serves as an essential trace element required for enzymatic activity, connective tissue maintenance, antioxidant protection, and normal cellular metabolism.

Research indicates that GHK-Cu functions as a signaling peptide capable of influencing multiple biological pathways associated with tissue remodeling, extracellular matrix maintenance, and cellular communication. Experimental investigations suggest that it supports collagen formation, elastin organization, fibroblast activity, angiogenesis, and antioxidant defenses while helping regulate inflammatory responses during tissue repair.

These characteristics have positioned GHK-Cu among the most extensively researched regenerative peptides in modern peptide science.
