What GHK-Cu is and its research context
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide-copper complex first identified in human blood plasma by Loren Pickart in the 1970s. The tripeptide backbone Gly-His-Lys coordinates a single Cu2+ ion (CAS 89030-95-5; molecular weight 401.91 Da; formula C14H23CuN6O4), forming a compact metallopeptide with a characteristic blue colour in solution.
GHK-Cu is studied in preclinical research on extracellular-matrix remodelling, fibroblast signalling, antioxidant-enzyme expression and the modulation of gene expression in cell-culture models. The copper peptide is one of the most frequently cited compounds in this field and is often used as a reference material when comparing other copper peptides such as AHK-Cu.
Specification and quality
- Format: 100 mg of lyophilised GHK-Cu per vial.
- Purity: ≥99%, verified per batch by HPLC and mass spectrometry.
- Certificate of analysis: every batch is analysed by an independent third-party laboratory and published on the lab results page, matched to the lot number on the vial.
- Appearance: lyophilised powder that forms a clear blue solution when reconstituted, a direct consequence of the copper coordination.
- Storage: keep sealed vials cool, dry and protected from light; refrigerate reconstituted solution.
GHK-Cu is also available as the GHK-Cu Pen (50 mg in 3 ml) and as a component of the KLOW and GLOW blends and The Recovery Protocol bundle. The peptide reconstitution calculator converts the 100 mg vial mass and a chosen diluent volume into a concentration.

Frequently asked
13 questionsHow fast is delivery and which carriers do you use?
Orders placed before 16:00 CET ship the same business day from the Netherlands via DPD or PostNL. EU-wide delivery typically takes 2–5 working days, fully tracked. Every parcel ships in plain, unbranded packaging with no peptide-related markings visible.
Which payment methods do you accept?
We accept iDEAL (Netherlands), Bancontact (Belgium), Klarna pay-later, SEPA instant bank transfer, and Visa/Mastercard credit and debit cards. All payments are processed through PCI-DSS-compliant European processors. Bank transfer and card orders ship within 24 hours of payment confirmation.
How do you verify peptide purity?
Every batch is HPLC-tested to 99% purity or higher by an independent third-party laboratory, with identity confirmed by mass spectrometry. The batch-specific Certificate of Analysis is published on every product page and delivered with the order.
Are research peptides legal to buy in the Netherlands and EU?
Yes — when sold and purchased strictly for in-vitro laboratory research. Research peptides on my\PEPT.eu are not approved, marketed or intended for human or veterinary use, medical diagnosis or therapeutic application. By placing an order you confirm research-only intent and accept responsibility for compliance with local regulations.
How should research peptides be stored?
Lyophilized (freeze-dried) peptides keep up to 24 months at −20 °C in a sealed vial. Once reconstituted in bacteriostatic water, store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles and direct sunlight.
What is GHK-Cu as a research peptide?
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a tripeptide-copper chelate with a molecular weight of approximately 340 Da, studied in laboratory research for its interactions with metalloproteinase pathways and cell signalling. It is intended for laboratory research only — not for human or veterinary consumption.
How should GHK-Cu be stored?
Keep sealed vials cool, dry and protected from light. After reconstitution with bacteriostatic water, refrigerate the solution and use it within the window set by your laboratory's procedures. Label the vial with the date and the concentration you calculated.
What does the Certificate of Analysis show for GHK-Cu?
The batch-specific CoA for GHK-Cu confirms HPLC purity at 99 % or above, copper-complex identity by mass spectrometry, batch number, and net content. Download it directly from the GHK-Cu product page. Research-use only — not for human use.
What is GHK-Cu?
GHK-Cu is a naturally occurring complex of the tripeptide glycyl-L-histidyl-L-lysine and a copper ion, first identified in human plasma. It is studied in preclinical research on extracellular-matrix remodelling and cellular signalling. myPEPT supplies it as a 100 mg lyophilised research peptide for laboratory use only.
Why does GHK-Cu turn blue when reconstituted?
The blue colour comes from the copper ion coordinated by the tripeptide. When the lyophilised powder dissolves in bacteriostatic water, the copper complex gives the solution a clear blue tint. This is a normal property of the compound and a quick visual confirmation that the material is a copper peptide.
How is GHK-Cu purity verified?
Every batch is analysed by an independent third-party laboratory using HPLC and mass spectrometry and must reach at least 99% purity. The certificate of analysis is published on our lab results page, and the lot number on the certificate matches the lot number on the vial.
Does myPEPT ship GHK-Cu to Ireland and the rest of Europe?
Yes. GHK-Cu ships within Europe, including Ireland, with tracking on every parcel. Customers in Ireland can pay by card, PayPal, Klarna or SEPA transfer; other countries see their local options at checkout. Support is available for batch and certificate questions.
What does research use only mean for GHK-Cu?
GHK-Cu from myPEPT is sold exclusively for laboratory research and is not for human consumption. We make no medical or cosmetic claims and do not provide instructions for use in people. Buyers confirm their research purpose at checkout and are responsible for compliance with the rules that apply to them.
