Description
GHK-Cu is a metallopeptide: a 1:1 copper(II) coordination complex of the tripeptide glycyl-L-histidyl-L-lysine, not a peptide on its own. The copper-free tripeptide GHK carries a separate registry entry, and the two are distinct materials.
This is also why listings report conflicting molecular weights. The lower figures describe the copper-free peptide and the higher figures the complex, with further variation from hydration and protonation state. The value on the certificate of analysis for your specific lot governs, and any figure quoted without a lot reference should be treated as approximate.
Investigated in in-vitro systems for copper coordination chemistry, matrix metalloproteinase assay behavior, and fibroblast culture models. No human data is presented, referenced, or implied.
Hygroscopic; protect from moisture as well as light.
Supplied strictly for laboratory research use only. Not a drug, food, cosmetic, or medical device. Not for human or animal consumption, and not for diagnostic or therapeutic use. Purchase confirms the buyer is a qualified researcher and accepts sole responsibility for lawful handling, storage, and disposal under all applicable regulations.
