What can rat wound studies tell us—and not tell us—about GHK-Cu and connective tissue?
Rat wound studies show that GHK-Cu (glycyl-L-histidyl-L-lysine-copper) can stimulate connective tissue accumulation, including collagen and glycosaminoglycans, in vivo. However, these findings are limited to animal models and cannot be directly translated to human outcomes or clinical recommendations. The mechanisms and potential applications in humans remain uncertain and require further research.

What does GHK-Cu research show about extracellular matrix biology?
GHK-Cu (glycyl-L-histidyl-L-lysine-copper) research demonstrates its ability to stimulate extracellular matrix (ECM) accumulation in animal models and modulate gene expression in cell lines. However, these findings are limited to preclinical contexts, and there is no direct evidence supporting the benefit or safety of retail GHK-Cu products, such as GHKCU 100 MG, in humans. All research products are for laboratory use only.
