About GHK-Cu
What is GHK-Cu?
Overview
What is GHK-Cu?
GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine. It is supplied as a lyophilised powder in sealed vials, boxed in tens, for laboratory research use only. The hyphen moves around in common usage — GHK-Cu, GHK Cu and GHKCu all name the same complex, and a search for a GHK Cu peptide supplier or for copper peptide GHK-Cu is looking for this compound. For the background on what the published work actually covers, see our copper peptides and GHK-Cu explainer.

These are catalogue target specifications, not batch results. The 99%+ purity figure is the specification we buy to. The authoritative figures for any particular box are the ones printed on that box’s Certificate of Analysis, which is lot-specific. What research grade actually means explains the difference. Terms such as HPLC purity and net peptide content are explained in the peptide glossary.
We make no “third-party verified” claim for a batch unless the matching report is supplied with it. Ask for the current COA for the lot in stock before you order — we will send it.

Storage & reconstitution
Handling
How should GHK-Cu be stored and reconstituted?
Sealed vials tolerate ambient temperature in transit and keep at −20 °C beyond that. Reconstitute slowly down the vial wall, swirl rather than shake, then refrigerate at 2–8 °C and aliquot before freezing.
Why each of those matters, and what a freeze–thaw cycle actually costs: peptide handling and storage reference. How long a mixed vial keeps: reconstituted peptide shelf life.
What it is researched for
Research Context
What is GHK-Cu researched for?
Below is a plain-English summary of what published research has investigated, and what it has found. These are descriptions of research activity and published results. They are not claims about what GHK-Cu does, and nothing here is a statement that it is safe or effective for any purpose.
Collagen and extracellular matrix
In fibroblast culture GHK-Cu increases production of collagen and other structural proteins that form the scaffold around cells. This is the most reproduced finding and the reason the peptide appears in skincare formulation research. 1
Copper delivery
The peptide binds copper(II) tightly but reversibly, allowing it to carry the ion to enzymes that require it. Several of those enzymes are directly involved in building and cross-linking collagen, which links the two findings together.
Gene expression profiling
Broad screening studies report GHK-Cu shifting expression across a large number of genes in cultured human cells. That breadth is what pushed interest beyond its original wound-healing context, though it also makes specific effects harder to isolate. 1

Batch COA
Verification
Does GHK-Cu come with a COA?
Yes — every box. Each batch of GHK-Cu is analysed by an independent third-party laboratory, and the certificate is tied to the batch number on the vial label.

Questions & answers
Questions
GHK-Cu questions, answered
What is GHK-Cu?
GHK-Cu is a copper-binding tripeptide: the three-amino-acid sequence glycyl-L-histidyl-L-lysine complexed with a copper(II) ion. The peptide was first isolated from human plasma in 1973, and the same sequence occurs within type I collagen. Written variously as GHK-Cu, GHK Cu, GHKCu or copper peptide GHK-Cu, all of which name this one complex.
Why is reconstituted GHK-Cu blue?
The colour comes from the bound copper(II) ion. Copper complexes absorb light in the red region of the visible spectrum, so the solution appears blue. A distinctly blue solution on reconstitution is expected for GHK-Cu and is not a sign of contamination.
How much does GHK-Cu cost?
GHK-Cu starts at $6.73 per vial, sold in boxes of 10 vials at $67.28 per box (about £50.41). 2 strengths available: 50 mg, 100 mg. There is no minimum order.
Can I buy GHK-Cu 50mg vials in the UK?
Yes. GHK-Cu 50mg comes in boxes of 10 vials at $67.28 per box ($6.73 per vial, about £50.41 per box), sent tracked to UK addresses. There is no minimum order.
Do you ship GHK-Cu to the US?
Yes, to all 50 states. GHK-Cu ships FedEx tracked from our UK stock or direct from our verified manufacturer, arriving 5 to 8 working days after dispatch, and is billed in US dollars from $6.73 per vial. We hold no US stock. If US customs seize an order, we reship it once at no cost. Our guide for US buyers covers US shipping, customs and pricing in full.
How is GHK-Cu shipped to the UK and USA?
Tracked to the UK, USA, EU and worldwide, in plain packaging, dispatched within 1–2 working days. Country-by-country estimates are on the shipping page.
