As with many research compounds, investigators study GHK-CU to better understand how it interacts with biological systems under controlled conditions

The peptide accelerates regeneration of intestinal mucosa and submucosa, restores tight junction proteins (claudin-1, occludin, ZO-1) that fail in intestinal permeability syndromes, and increases local blood supply through VEGF-mediated angiogenesis

Copper peptide GHK-Cu is a short chain of amino acids that naturally occurs in the body, found in saliva, urine, and cell plasma

Its small molecular weight (~390 Da) supports cellular uptake and is reported to enable direct DNA / chromatin interaction at gene promoter regions, consistent with the broader Khavinson bioregulator hypothesis
