GHK-Cu (copper peptide GHK) is a naturally occurring tripeptide-copper complex first isolated from human plasma in the 1970s. Its presence in the body declines with age, which has made it a subject of interest in cellular and tissue biology research — particularly in studies exploring how copper-peptide signaling influences repair and remodeling processes at the cellular level.
Research has investigated GHK-Cu across a wide range of tissue models. Studies have explored its role in fibroblast activity, collagen and elastin synthesis signaling, and matrix metalloproteinase regulation — all relevant to how connective tissue is maintained and remodeled. It's considered one of the more biologically active copper-binding peptides identified in human biology.
In addition to tissue remodeling research, GHK-Cu has been studied in models examining anti-inflammatory signaling, nerve outgrowth, and DNA repair pathway modulation. Its versatile research profile across skin, wound, and nerve tissue models has contributed to a substantial body of published literature on copper peptides in regenerative biology.
myPEPT supplies GHK-Cu at ≥99% verified purity with a Certificate of Analysis from independent testing. It's available in lyophilized form and ships across the EU in properly sealed, research-grade packaging.
What researchers should know: GHK-Cu is supplied for laboratory research purposes only. It is not a cosmetic ingredient or therapeutic product in this form. Handle and store according to your institution's compound management guidelines and applicable local regulations.

Frequently asked
8 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), PayPal, 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?
Lyophilized GHK-Cu should be stored at −20 °C in a sealed vial, protected from light. Once reconstituted in bacteriostatic water, refrigerate at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles. Supplied for in-vitro research use only.
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.
