Understanding these helps set realistic expectations and optimize your protocol

As shown in Figure 8, the results from Western blotting showed that GHK-Cu had little effect on LPS-induced phosphorylation of ERK1/2, however, it significantly reduced the phosphorylation of p38 MAPK and JNK1/2 in LPS + 10 g/g GHK-Cu group compared to the LPS group

GHK-Cu does not directly interact with cytoskeletal proteins but instead operates through copper-dependent enzymatic activation and transcriptomic reprogramming

The most cited longevity study involved chronic Epithalon administration in female CBA mice, where the peptide extended median lifespan by 13.3% compared to untreated controls

The published research has reported antioxidant-like effects in cell-culture systems and effects on antioxidant gene expression, consistent with the chelation and delivery roles
