GHK-Cu / prezatide copperGHK-Cu research guide
A guide to Gly-His-Lys identity, copper-complex registry notes, and coordination chemistry papers.
01 - Short version
The quick read.
Plain-language context only. No preparation steps, no use instructions, and no product-effect claims.
New to GHK-Cu? Here's the short version. GHK-Cu is the copper-bound form of Gly-His-Lys.
Free GHK and GHK-Cu have separate registry records, so this guide keeps both identifiers visible.
The current reference set sits in identity, copper binding, coordination chemistry, and cell-model gene-expression context.

Identity information lets you compare the guide with the product label. It is not a certificate, mixing method, or instruction for use.
03 - What studies look at
The main research themes.
Each note stays at study-context level and avoids use instructions.
01GHK sequence recordSchlesinger et al., Experientia, 1977.
This paper anchors the Gly-His-Lys sequence.
02Copper-complex paperPickart et al., Nature, 1980.
The guide reports copper-complex context without making product claims.
03Cu(II)-GHK interactionLau and Sarkar, Biochem J, 1981.
This paper supports the coordination-chemistry section.
Storage, appearance, purity, and release state come from the matching lot record.
Use the product label and matching COA as the authority for storage, appearance, purity, and release state.
This guide is educational context only. It does not include preparation, administration, human-use, or veterinary-use directions.
For laboratory research use only. 18+ only. Not for human consumption or veterinary use.
05 - FAQ
Common questions.
What is GHK-CU supplied for?
GHK-CU is supplied as laboratory research material only. It is 18+ only, not for human consumption, and not for veterinary use.
Does this page include matching COA information?
Yes. The product page lists lot, identity, purity, appearance, release status, and storage notes for GHK-CU.
How should the vial be handled after delivery?
Follow the label and matching COA paperwork. This page repeats 2-8 C storage guidance and light-protection notes before checkout.
What is GHK-Cu supplied for?
GHK-Cu is supplied strictly as a laboratory research material. It is not for human or veterinary use, and it is not sold for medical, cosmetic, diagnostic, or household use.
Is free GHK the same as GHK-Cu?
No. Free GHK and the copper complex have separate registry records, so the page keeps both identifiers visible and points back to the COA for the actual lot.
What details should be checked before ordering?
Check the compound name, 50 mg size, lot 24-0417, 98.7% HPLC purity, 2-8 C storage, and protect-from-light note against the product label and COA.
