Research Compound
Buy GHK-Cu in Europe — Research Use Only
GHK-Cu is the copper-bound form of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine, widely used in skin, wound-healing, and cosmetic-formulation research. It is supplied here as a lyophilised research compound for in-vitro laboratory use only — not for human or animal use. If you are a European researcher deciding where to source it, this page covers what to check in a supplier and precisely how CertaPeptides supplies the copper peptide.
What to verify before buying GHK-Cu
Any supplier can claim purity. These four checks separate documentation from marketing — apply them to us and to anyone else you are evaluating.
Batch-level third-party COAs
A blanket purity claim is not evidence. Confirm the supplier publishes certificates of analysis from an independent laboratory, tied to the batch number on the vial — and that you can verify each report on the testing lab's own portal, not as a screenshot they control.
Where it ships from
For an EU-based laboratory, an EU-internal supplier means no customs clearance: no held parcels, no import paperwork, no surprise fees, and shorter transit. Every border crossing is a failure point for time-sensitive research material.
Payment options that work in Europe
Check which payment rails the supplier supports from your country and what happens when a payment fails. For European research purchases, SEPA bank transfer is the reliable baseline.
Supplier transparency
An honest supplier tells you what it is and is not. A reseller should say it resells; a manufacturer should prove it manufactures. Reconstitution data, storage guidance, and a support channel that answers within a business day round it out.
How CertaPeptides supplies GHK-Cu
CertaPeptides is a reseller, not a manufacturer. We buy GHK-Cu from a research-compound supplier and ship it as supplied, against that supplier's batch specification of at least 98% HPLC purity — the copper complexation and the form are determined by the supplier, not by us.
Selected GHK-Cu lots are independently tested by Janoshik Analytical, with the certificate published in our COA Vault and verifiable on Janoshik's own portal. We publish every report we commission rather than only the convenient ones.
Point by point against that same checklist — including the parts where we simply tell you how it is.
Batch COAs, including the unflattering ones
Selected lots are independently tested by Janoshik Analytical, and the reports are published in our COA Vault — verifiable on Janoshik's own portal, which we do not control. We publish every report we commission. Everything else ships against the supplier's batch specification: we are a reseller, not a manufacturer, and we document accordingly. The full testing framework is on our quality page.

Frequently asked questions
What purity is GHK-Cu supplied at?
GHK-Cu ships against the supplier's batch specification of at least 98% HPLC purity. Independently tested lots have their measured purity and chromatogram published in our COA Vault and verifiable on Janoshik's portal.
Why is GHK-Cu blue, and is that normal?
The blue colour comes from the copper(II) ion that is part of the GHK-Cu complex — it is expected for this compound. We supply the copper-bound form exactly as our supplier provides it; we do not formulate or alter it.
Is it legal to buy GHK-Cu for research in the EU?
GHK-Cu is supplied strictly as a research compound for in-vitro laboratory use, labelled and sold on that basis, and ships routinely within the EU as research material. Regulations vary by country and by intended use, so confirm the rules that apply to your laboratory — this is general information, not legal advice. It is not supplied for human or animal use.
How is GHK-Cu shipped, and where?
Orders ship from Romania to all 27 EU countries plus the UK, Switzerland, Norway, Iceland, Israel, and Serbia. Intra-EU parcels clear no customs. Shipping starts at €4.99 and is free over €200, with typical EU transit of 2–5 business days.
How do I verify the certificate of analysis?
Match the batch number printed on the vial to its certificate in our COA Vault, then confirm the same report on Janoshik Analytical's own portal — independent verification we cannot edit. Lots without an independent report ship against the supplier's documented batch specification.
What payment options are available?
SEPA bank transfer and instant SEPA via Paysera's hosted online-banking page, across the whole SEPA zone. Card payments are not currently offered.
