Copper peptides

Copper peptides are small peptides that bind copper(II) ions tightly. GHK-Cu, found naturally in human plasma, is one of the most studied molecules in extracellular-matrix and collagen research, and broad gene-expression data suggest it acts on many cellular pathways. AHK-Cu is a close analogue used in cell-culture work on copper-peptide signalling. Both are supplied lyophilized with an independent lab report for each batch. See our GHK-Cu research overview for the science and handling tips.
