- GHK-Cu has been observed to modulate gene expression more broadly than other copper peptides (e.g., Cu-GHK without histidine) in some studies. Researchers conducting comparative copper-peptide studies in preclinical models typically require accurately stoichiometrically verified material; the GHK-Cu copper-binding tripeptide reference compound is synthesized with a confirmed 1:1 copper-to-peptide ratio verified by mass spectrometry, which is an important variable in receptor-binding and gene-modulation studies.
