Overview
GHK-Cu — Copper-tripeptide complex
What is GHK-Cu?
GHK-Cu is a copper-bound tripeptide: glycyl-L-histidyl-L-lysine complexed 1:1 with copper(II). First isolated from human plasma in 1973, it carries five decades of research across tissue-remodelling, skin, and biological-signalling contexts — few research peptides are better characterised.
Why researchers choose it
The copper coordination is the point: the complex, not the bare tripeptide, is what most of the literature has studied, so the peptide-to-copper ratio matters as much as sequence purity. At three residues, GHK is also the smallest peptide in the catalogue — simple to handle, stable, and forgiving in the lab. REPRIME supplies the complex as lyophilized 50 mg and 100 mg vials, leaving concentration decisions to the researcher.
The REPRIME standard
Every batch is independently HPLC-verified at ≥99% purity, with identity and composition documented on a public COA before you buy. Cold-chain delivery, tamper-evident packaging, and a unique REP-XXXX-XXXX-X code confirm each vial's authenticity at first scan. For laboratory and research use only.
Storage
Store lyophilized at -20°C. After reconstitution, refrigerate at 2-8°C.
Research use only
For laboratory and research use only. Not for human or animal consumption.

FAQ
Frequently asked questions.
What is GHK-Cu made of?+
GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine bound to copper(II) — a naturally occurring complex widely used in tissue and skin research.
What purity is REPRIME's GHK-Cu?+
The 50 mg and 100 mg lyophilized vials are HPLC-verified at ≥99% purity, each with a batch-specific COA published on the product page.
How do I verify the product is authentic?+
Each vial's insert carries a unique code in the format REP-XXXX-XXXX-X. Enter it on the /verify page — the first scan stamps it verified; a later scan warns the code has already been used.
