Buy GHK-Cu

Buying GHK-Cu here comes in two forms: a lyophilised vial of 100 mg and a pre-filled research pen of 100 mg. At 0,90 euro per milligram for the vial this is the cheapest peptide per milligram in our catalogue by a wide margin.

What GHK-Cu is, and why it is called copper peptide

GHK-Cu is a tripeptide copper complex, chemically Gly-His-Lys bound to divalent copper, first isolated in 1973. Copper peptide is not a marketing name but a literal description: the copper ion is part of the molecule, not an additive.

You can recognise it by colour. The lyophilised powder is blue tinted, and that tint comes directly from the bound copper centre. White powder is not GHK-Cu. That is the fastest plausibility check you can run without a lab.

The research mechanism

• Activation of dermal fibroblasts: upregulation of type I collagen, decorin and elastin
• Bidirectional modulation of matrix metalloproteinases
• Antioxidant activity through the copper centre
• Anti-inflammatory dampening of cytokines

A vial is not a serum

This is where most confusion arises. We supply GHK-Cu as lyophilised powder in a vial or as a premixed solution in a pen. Both are research material with a documented content of 100 mg.

A cosmetic serum containing copper peptide is a different thing: a finished skincare product with a concentration expressed in tenths of a percent, not milligrams per vial. Anyone searching for copper peptide serum is usually looking for that cosmetic product. We do not sell it.

How to judge a peptide supplier

The research peptide market is not regulated the way a pharmacy is. The difference between suppliers therefore lies entirely in what they can demonstrate, not in what they claim. Four points are enough.

A certificate per batch, not per product. A certificate attached to a product page rather than to your specific batch number tells you nothing about the vial in your hands. Ask for the batch number.

Two independent methods. HPLC shows purity, mass spectrometry confirms the compound is what the label says. HPLC alone is half the story. Karl Fischer titration measures water content on top of that, which is directly tied to how long the powder stays stable.

A cold chain that matches the distance. Lyophilised peptide tolerates room-temperature transport less well the longer it lasts. A shipment weeks in transit from another continent is a different product than the same powder that stayed within the EU.

A payment method that leaves a trail. Wero, credit card, Apple Pay and Google Pay all do. Suppliers who accept only crypto deliberately avoid that.

What is in the package

• The sealed vial or pen in your chosen format, batch traceable
• Protective cold packaging, cold chain within the EU
• Discreet outer packaging with no reference to the contents
• Certificate of analysis on request, tied to your batch number

We do not include bacteriostatic water or needles. That is deliberate: we sell the research compound, not the accessories.

Reconstitution and storage

Reconstitute the vial with sterile bacteriostatic water at 3 to 5 ml, giving working concentrations of 20 to 33 mg per millilitre. Note one thing specific to GHK-Cu: the copper centre is sensitive to reducing conditions, so avoid reducing agents in your buffers. Reconstituted material stays stable roughly four weeks refrigerated. The pen holds a premixed solution and needs nothing added.

Paying from anywhere in the EU

You complete your order first. You then reach a secure payment page showing the exact amount and your order number, where you choose how to pay: Wero, credit card, Apple Pay or Google Pay. Which methods appear depends on the country you are paying from. No card number is entered on our site.

Shipping and customs across Europe

We ship from within the EU with cold chain. For any EU destination that means no customs clearance, no import duty and no gap in temperature control. Sunday is the only day we do not ship. Above 200 euro shipping is free.

One thing worth stating plainly, because it comes up constantly in English searches: the United Kingdom is no longer in the EU. A shipment there goes through customs clearance with a delay we cannot control, and a customs depot is not a cold room. The same applies to Switzerland and Norway. We say this before you order rather than after.

Research use only

What we supply are research compounds for laboratory use. They are not a medicine, are not sold as one, and are not intended for human consumption. That distinction is the entire legal point: a research compound falls under different rules than an approved medicinal product.

For that reason we give no dosage, no protocol and no usage advice. What we do give is documentation.

Frequently asked questions

How do I recognise genuine GHK-Cu?

By the blue tinted powder. The tint comes from the bound copper centre. White powder is not GHK-Cu.

Do you sell a serum?

No. We supply GHK-Cu as lyophilised powder in a vial and as a premixed solution in a pen, both as research material.

Which is cheaper per milligram, vial or pen?

The vial at 0,90 euro per milligram against 1,10 for the pen.

Why avoid reducing agents in buffers?

Because the copper centre is sensitive to reducing conditions. With most peptides this does not matter, with a metal complex it does.

How do I reconstitute it?

With sterile bacteriostatic water at 3 to 5 ml, giving 20 to 33 mg per millilitre.

Do you ship to the UK?

The UK left the EU, so customs clearance applies.

How can I pay?

With Wero, credit card, Apple Pay or Google Pay.

What may I use this for?

Laboratory research only. Not for human consumption, not a medicinal product and not for diagnostic use.

For research purposes only. Not for human consumption. Not a medicinal product. Not for diagnostic use.
