Overview
GHK-Cu is a naturally occurring copper-binding tripeptide studied for its role in molecular signaling, matrix remodeling, and pathway dynamics.
History
GHK was first identified in the 1970s in plasma samples; complexing it with copper enhanced biological activity in matrix dynamics.
Structure and mechanism
GHK-Cu is a copper-binding tripeptide — glycyl-L-histidyl-L-lysine — complexed with a divalent copper ion, giving a molecular formula of C₁₄H₂₂CuN₆O₄ and a characteristic deep blue colour in solution that is itself a rough visual indicator of intact copper coordination. The free peptide GHK and the copper complex GHK-Cu are different reagents and behave differently in assay conditions.
The histidine imidazole and the N-terminal amine together form the copper-binding site, and it is this coordination chemistry that drives most of the preclinical interest in the molecule: in laboratory models it is studied in relation to matrix remodeling signaling, copper transport, and fibroblast gene-expression work.
Reconstitution and handling (research use)
GHK-Cu is supplied as a lyophilized powder in 50 mg and 100 mg vials. For in-vitro laboratory use it is reconstituted with bacteriostatic or sterile water. The copper coordination is pH-sensitive, and chelating agents such as EDTA in a working buffer will strip the copper and leave the free peptide — a common source of inconsistent results when the reagent is assumed to be inert to buffer composition.
Lyophilized material is stored at -20°C protected from light; reconstituted solution is refrigerated at 2-8°C. Loss of the blue colour indicates the complex has dissociated. General reagent handling guidance only; not for human or veterinary use.
Wholesale sourcing notes
GHK-Cu is the highest-volume compound in the anti-aging and longevity category and is stocked in both 50 mg and 100 mg vials as well as a 25 mg nasal spray presentation. All material is sourced in the USA and independently verified by a third-party lab.
Copper content is the variable that matters most on this compound: an underspecified GHK-Cu can assay correctly for peptide identity while carrying incomplete copper coordination. A per-lot Certificate of Analysis is included with every order at no charge, issued in the name of Wholesale Peptide Supply.

GHK-Cu — Frequently Asked Questions
- What is GHK-Cu?
- GHK-Cu is a naturally occurring copper-binding tripeptide studied for its role in molecular signaling, matrix remodeling, and pathway dynamics.
- What is the CAS number for GHK-Cu?
- The CAS number for GHK-Cu is 89030-95-5. Its molecular formula is C₁₄H₂₄CuN₆O₄ (MW 340.9 g/mol).
- What doses of GHK-Cu are available wholesale?
- Wholesale Peptide Supply stocks GHK-Cu in 50mg, 100mg. Wholesale pricing is provided by quote based on order volume, from a 3-kit (30-vial) order minimum, mix and match across doses and compounds.
- Is GHK-Cu third-party tested?
- Yes. Every lot of GHK-Cu is tested by an independent third-party laboratory, and a per-lot Certificate of Analysis is included with every order at no charge, issued in the name of Wholesale Peptide Supply. The most recent published lot, 100089-0930 (100mg), was tested by Optiq Health Labs on 20 August 2026 by RP-HPLC / LC-MS. Every lot on file is listed with its certificate on this page.
- Is GHK-Cu for human use?
- No. GHK-Cu is sold strictly as a chemical reagent for in-vitro laboratory research and is not for human or veterinary use. Wholesale Peptide Supply is not a pharmacy or compounding facility.
- How do I get wholesale pricing for GHK-Cu?
- Request a quote through our contact form or open a wholesale account. An account manager replies with volume pricing and lead times the same day. For anything urgent, text or call (714) 625-9215 to reach a real person in the US.
- Can I order GHK-Cu in bulk?
- Yes. GHK-Cu is available for bulk and wholesale orders, quoted by dose and volume, from a 3-kit (30-vial) order minimum, mix and match across doses and compounds, with lower prices at 10 kits and at 100 kits (1,000 vials) in the order. Submit the doses and quantities you need for a bulk quote.
- Why is GHK-Cu blue?
- The colour comes from the coordinated copper(II) ion. Glycyl-L-histidyl-L-lysine binds copper through its histidine imidazole and N-terminal amine, and the resulting complex absorbs in the visible range. A GHK-Cu solution that is colourless or has lost its blue tint indicates the copper has dissociated, leaving the free peptide — which is a different reagent.
- Will EDTA or a chelating buffer affect GHK-Cu?
- Yes. Chelating agents such as EDTA will strip the coordinated copper and leave free GHK. This is a frequent source of inconsistent results when the compound is treated as inert to buffer composition. Buffer selection matters for this reagent in a way it does not for most peptides in the catalog.
