What is GHK-Cu?
GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine, also catalogued as copper tripeptide-1 or prezatide copper. It carries the molecular formula C14H23CuN6O4+ at a molecular weight of 402.92 g/mol, registered under CAS 89030-95-5 and PubChem CID 71587328. It is supplied here strictly as a laboratory reference material.
The tripeptide backbone (Gly-His-Lys) coordinates a single copper ion through its histidine and amine groups, which is why GHK-Cu is grouped with the copper peptides rather than the unliganded GHK sequence. The distinctive deep-blue colour of the reconstituted material comes from that copper coordination, not from any additive.
Is GHK-Cu legal in the UK?
GHK-Cu is not a controlled substance under the Misuse of Drugs Act 1971 and is not a scheduled drug in the UK. It is supplied by Kovalabs for laboratory research use only. It is not a medicine, holds no marketing authorisation, and cannot be sold or supplied for human consumption, ingestion, injection, topical application, or any in-vivo use. The purchaser is responsible for ensuring lawful, appropriate handling within a controlled research setting. See our research disclaimer for the full terms.
How is the identity and quality assured?
Identity and purity are verified per lot, not assumed. Each lot is assayed to a minimum 99% purity by HPLC and released with a batch-specific Certificate of Analysis documenting the chromatographic purity and identity. The verified identifiers for this material are CAS 89030-95-5, PubChem CID 71587328, molecular formula C14H23CuN6O4+, molecular weight 402.92 g/mol, and the Gly-His-Lys copper-complex composition. Because related GHK records are indexed separately in public databases, confirming the CAS and CID against the documentation matters. Current certificates are published on our CoA page.
What does the research on GHK-Cu investigate?
GHK-Cu appears in the research literature largely in the context of collagen, extracellular-matrix remodelling, and copper-dependent cellular processes, alongside gene-expression profiling work. These are descriptions of laboratory and pre-clinical research questions, not outcomes. None of this body of work establishes a benefit, effect, or outcome in humans, and the leap from an in-vitro or animal observation to a human result is not supported by it. The detailed evidence audit, with the study designs and their limitations, lives in our monograph on GHK-Cu copper peptide research rather than here.
Synthesis and supply
GHK-Cu is supplied as a lyophilised research powder and may be reconstituted with a suitable solvent such as bacteriostatic water for laboratory use. Researchers comparing extracellular-matrix reference peptides often also reference BPC-157 and TB-500, and the full range sits within our tissue repair category. All material is despatched from the UK with its accompanying Certificate of Analysis.

- What is GHK-Cu?
- GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, also known as copper tripeptide-1 or prezatide copper. It has the molecular formula C14H23CuN6O4+, a molecular weight of 402.92 g/mol, CAS 89030-95-5 and PubChem CID 71587328. Kovalabs supplies it as a research reference material only.
- Is GHK-Cu legal in the UK?
- GHK-Cu is not a controlled drug under the Misuse of Drugs Act 1971 and is not scheduled in the UK. It is supplied for laboratory research use only, holds no marketing authorisation, and cannot be sold or supplied for human consumption or any in-vivo use. The purchaser is responsible for lawful handling.
- What does the research on GHK-Cu investigate?
- Published work references GHK-Cu in the context of collagen, extracellular-matrix remodelling, copper-dependent cellular processes and gene-expression profiling. These describe laboratory and pre-clinical research questions, not established outcomes. None of it demonstrates a benefit or effect in humans. The detailed evidence audit is in our blog monograph.
- Has GHK-Cu been shown to be safe or effective in humans?
- No. GHK-Cu has not been evaluated by any regulator as a medicine and holds no marketing authorisation. The literature describes pre-clinical and in-vitro research questions, none of which establishes a benefit or effect in humans. It is supplied strictly as a research chemical for laboratory use.
- Can GHK-Cu be taken orally, injected or applied topically?
- No. GHK-Cu is supplied as a research chemical for laboratory use only and is not for human consumption. It is not a cosmetic, supplement or medicine, so it must not be ingested, injected, applied to skin, or used in any in-vivo way. Any handling is confined to a controlled research setting.
- Can GHK-Cu be combined with BPC-157?
- Kovalabs offers no guidance on combining research compounds in any living system, because none of these materials is for human or animal use. GHK-Cu and BPC-157 are sold separately as laboratory reference materials only; any handling is a research procedure, not a protocol for in-vivo use.
- Is all GHK-Cu the same?
- No. Quality and identity vary by source. Confirm the material against its verified identifiers (CAS 89030-95-5, CID 71587328, formula C14H23CuN6O4+, MW 402.92 g/mol) and demand a batch-specific Certificate of Analysis. Kovalabs assays every lot to a minimum 99% HPLC purity and publishes the CoA.
- What is the difference between GHK-Cu and a copper peptide?
- GHK-Cu is a specific copper peptide: the copper(II) complex of the Gly-His-Lys tripeptide, catalogued as copper tripeptide-1. The term copper peptide is a broader category that includes other peptide-copper complexes, so GHK-Cu is one defined member of that group rather than a synonym for it.
- What is the molecular formula and weight of GHK-Cu?
- GHK-Cu has the molecular formula C14H23CuN6O4+ and a molecular weight of 402.92 g/mol. Its sequence is glycyl-L-histidyl-L-lysine (Gly-His-Lys) as a copper complex, with CAS 89030-95-5 and PubChem CID 71587328.
- Is GHK-Cu intended for human use?
- No. GHK-Cu is supplied by Kovalabs as a research reference material for laboratory use only. It is not a cosmetic, supplement or medicine and is not for human consumption, ingestion, topical application or any in-vivo application.
- How is GHK-Cu reconstituted for research?
- GHK-Cu is supplied as a lyophilised powder and can be reconstituted for laboratory use with a suitable solvent such as bacteriostatic water. The copper coordination gives the reconstituted material a characteristic blue colour. Reconstitution is a laboratory handling step only and does not imply any in-vivo use.
- How should GHK-Cu be stored?
- Lyophilised GHK-Cu is typically stored cold and protected from light and moisture; once reconstituted, research peptides are generally kept refrigerated. Refer to the documentation accompanying your batch for the storage guidance specific to that lot.
- Does GHK-Cu come with a Certificate of Analysis?
- Yes. Every batch is released with a batch-specific Certificate of Analysis showing chromatographic purity and identity, assayed to a minimum 99% by HPLC. Current certificates are published on the Kovalabs CoA page so the identifiers can be verified against the documentation.
- Can GHK-Cu be prescribed by a doctor?
- No. GHK-Cu holds no UK marketing authorisation, so it is not a licensed prescription product. Kovalabs supplies it only as a research chemical for laboratory use and makes no claim about any clinical pathway.
- Is GHK-Cu a serum or cream?
- No. Kovalabs supplies GHK-Cu as a lyophilised research powder, not as a cosmetic serum, cream or skincare formulation. It is a laboratory reference material for research use only, with no cosmetic, topical or in-vivo application. It is not a licensed medicine and holds no marketing authorisation. Researchers reconstitute the powder with a suitable solvent such as bacteriostatic water for bench work only.
- Does GHK-Cu have side effects?
- No human safety profile has been established. GHK-Cu has not been evaluated by any regulator as a medicine, holds no marketing authorisation, and is supplied strictly as a research chemical for laboratory use, not for human consumption or any in-vivo use. The published literature describes pre-clinical and in-vitro research questions only and does not establish a safety or effect profile in humans.
