As a single 1 g vial of cosmetic-grade GHK-Cu powder for €229. Mix with a hyaluronic acid serum and apply topically — cosmetic use only.

Is GHK-Cu for injection or research?

No. This GHK-Cu listing is sold strictly as a cosmetic-grade raw ingredient for topical formulation. It is not for injection, ingestion or human/veterinary medical use.

What payment methods do you accept?

SEPA bank transfer (IBAN) is our default — secure, fee-free, instant confirmation. We can also send a secure card-payment link on request via WhatsApp.

Do you ship outside the EU?

Yes — UK, USA, Middle East, Asia and Australia. EU is fastest (5–18 business days). International is tracked and discreet. Some destinations are restricted — checkout will tell you.

How is purity verified?

Every batch is independently tested by HPLC and mass spectrometry. We can send the batch-specific COA for your order on request.

Is this intended for human use?

No. GHK-Cu sold by Regena Peptides is a research compound supplied strictly for in-vitro laboratory investigation by qualified professionals. Not for human or veterinary use.

What is the difference between GHK-Cu (Cosmetic) and GHK-Cu (Peptide)?

GHK-Cu (Cosmetic) is a single 1 g vial supplied as a raw cosmetic-grade ingredient for topical formulation. GHK-Cu (Peptide) is a separate injectable-format research kit (10 vials) for laboratory protocols. They are listed as distinct products.

How is the cosmetic vial prepared?

Reconstitute the 1 g GHK-Cu powder into a hyaluronic acid serum base per your formulation protocol and apply topically. It is a cosmetic-formulation ingredient, not a medicine.

Is GHK-Cu banned in sport?

GHK-Cu itself is not currently listed on the WADA Prohibited List, but always check the current-year list before any elite-sport protocol.

How should GHK-Cu be stored?

Sealed vial refrigerated at 2–8 °C; protect from light. Once reconstituted into a serum, follow your cosmetic-formulation stability guidance.

What purity level is guaranteed?

HPLC ≥99% with mass-spectrometry verification. Copper-complex ratio is validated per batch. COAs on request.

Can GHK-Cu be combined with retinol or vitamin C?

Formulation compatibility is protocol-specific. GHK-Cu is generally paired with hyaluronic acid or gentle emollient bases; strong actives are usually applied on alternate cycles.

What is GHK-Cu?

GHK-Cu is a naturally occurring copper-binding tripeptide that acts as a copper(II) chaperone, modulating ECM remodelling, antioxidant defence genes and dermal fibroblast activity.

Mechanism of action

Copper chaperone modulating ECM and antioxidant gene expression.

Primary research areas

Skin remodeling, hair follicle biology, wound studies.

Research notes

Sold as 1 vial of 1 g cosmetic-grade GHK-Cu powder for €229.
Mix with a hyaluronic acid serum and apply topically — cosmetic use only.
Frequently cited in cosmetic-science and wound-healing literature.

GHK-Cu: expanded research context

GHK-Cu is a naturally occurring tripeptide-copper complex (glycyl-L-histidyl-L-lysine bound to Cu²⁺). Endogenous plasma levels decline substantially with age. Its most robust published effects are on dermal fibroblast activity, wound-healing gene expression and antioxidant capacity — properties that have made it a mainstay of clinical-grade cosmetic formulation for over two decades.

Regena Peptides lists GHK-Cu in two distinct formats. The cosmetic-grade 1 g vial (this page's default) is a raw ingredient for topical formulation with hyaluronic acid serums. A separate injectable-format research kit is available under GHK-Cu (Peptide) for laboratory protocols that require sterile 10-vial packaging.
