Scientific profile

GHK-Cu at a glance

GHK binds copper very tightly. In lab studies on skin cells, this copper-peptide pairing has been linked to changes in the genes involved in building collagen and other parts of the skin's support structure, as well as acting as a carrier that helps deliver copper where it's needed.

01

What is GHK-Cu?

GHK is a natural tripeptide (glycine, histidine and lysine) first found in human blood. Its stand-out feature is how strongly it grabs onto copper. The GHK-Cu we supply is the copper-loaded form, which is why the mixed solution turns a deep blue.

Levels of GHK in the blood are known to drop as we get older, which is one reason it has drawn so much interest in skin and tissue research. It's one of the most heavily published copper-peptides in the scientific literature.

02

What researchers study GHK-Cu for

In studies on skin cells, GHK-Cu has been linked to changes in the genes that build the skin's support structure, including collagen (types I and III), elastin and other matrix components, while also helping slow the breakdown of that structure. This two-sided effect is why it's often used as a reference point in skin-remodelling experiments.

A separate area of study is copper delivery itself. Because several important enzymes need copper to work, researchers look at GHK-Cu as a way to carry copper into cells, not just as a signalling peptide. Broader gene-activity studies have reported effects across DNA repair, antioxidant and inflammation-related genes.

03

How to store and prepare GHK-Cu

GHK-Cu comes at a higher strength than most peptides in the range, because skin studies usually use higher concentrations. Mix it with bacteriostatic water added slowly down the vial wall, and the solution should turn a clear, deep blue. If it looks green or brown, the peptide has degraded and the vial should be thrown away.

It's sensitive to light. Keep the mixed solution in the fridge (2–8°C) in the dark and use within 30 days. Don't combine it with strong 'chelating' agents such as EDTA in the same solution, as they'll pull the copper away from the peptide.

Mechanism at a glance

GHK binds copper very tightly. In lab studies on skin cells, this copper-peptide pairing has been linked to changes in the genes involved in building collagen and other parts of the skin's support structure, as well as acting as a carrier that helps deliver copper where it's needed.

Certificates of analysis

Every batch tested. Every result published.

Samples from each GHK-Cu batch are sent to an independent, accredited UK laboratory. Purity is measured with a technique called HPLC, and identity is confirmed by mass spectrometry, before the batch is released.

Answers

GHK-Cu questions, answered

Can't find what you need? Our UK team answers technical enquiries within one working day.

Is GHK-Cu third-party tested?

Yes. Every batch of GHK-Cu is checked by an independent UK laboratory that's accredited to the ISO/IEC 17025 standard. They confirm its purity (using a technique called HPLC) and its identity (using mass spectrometry). The certificate for the exact batch you receive is published on this page before we put it on sale.

Where is it made and shipped from?

Everything (making the peptide, filling the vials and quality-checking each batch) happens in the UK at our facility on Alderley Park, the country's largest life-sciences campus. Your order is picked, packed and posted from the same site, so nothing crosses a border before it reaches you.

How quickly will my order arrive?

Orders placed before 3pm, Monday to Friday, are sent out the same working day on a tracked 24-hour UK service. Delivery is free on orders over £100. Everything ships in plain, unbranded packaging.

What does 99% purity actually mean?

It means at least 99% of what's in the vial is the peptide itself, with almost no leftover by-products. We measure this with a lab technique called HPLC, and only release batches that reach 99% or higher. The exact figure for your batch is printed on its certificate.

How does GHK-Cu come packaged?

GHK-Cu arrives as a freeze-dried powder in a sealed glass vial, with a flip-off cap and a tamper-evident seal so you know it hasn't been opened. You'll need bacteriostatic water to mix it (sold separately).

Can I save money by buying more than one vial?

Yes. Two vials save you 10% and three vials save 20% against the single-vial price.

Do I get a Certificate of Analysis with every order?

Yes. A certificate comes with every batch and can be downloaded from this page. It shows the batch number, the date it was made, the purity result, confirmation of identity, appearance, water content and a contamination (endotoxin) check.

Is this product for human use?

No. Everything we sell is supplied strictly as a research-grade compound for laboratory study by qualified researchers. These products are not medicines and are not intended for human or animal consumption, injection, diagnosis or treatment.
