GHK-Cu is a compound with the molecular formula C14H21CuN6O4- and a molecular weight of 400.90 g/mol (PubChem CID 139035031). Aegis Bio supplies it as lyophilised powder in 3 specifications, for in-vitro laboratory research use only.
Supplied against a ≥99% HPLC purity specification. Lots are analysed by Janoshik Analytical, an independent laboratory commissioned by the manufacturer, and Aegis Bio submits selected lots to Accumark in California for its own independent verification. The figure measured for the lot supplied is stated on its certificate of analysis, available by request before ordering. What each section of a COA establishes.

Cost per milligram
| Specification | Total material | Price | Cost per mg |
|---|---|---|---|
| 100 mg x 10 vials | 1000 mg | $105.00 | $0.105/mg |
| 50 mg x 10 vials | 500 mg | $98.00 | $0.196/mg |
| 100 mg x 1 vial | 100 mg | $30.00 | $0.300/mg |
Choosing a specification
GHK-Cu is listed in 3 specifications. Measured by cost per milligram — the only figure that compares cleanly across different strengths and vial counts — the best value is the 100 mg x 10 vials at $105.00, which works out to $0.105/mg. The least efficient listing is the 100 mg x 1 vial at $30.00, or $0.300/mg — a 2.9× premium per milligram.
The single 100 mg x 1 vial vial at $30.00 exists to evaluate the material before committing to pack quantities; the 100 mg x 10 vials pack brings the rate down to $0.105/mg. Whether that premium is worth paying depends on whether you will consume pack quantities within the material's useful life — unused material is not cheap material. Single vials also ship at the reduced $20.00 rate when ordered alone, and ride along free inside any order containing a pack.
Reconstitution reference
Resulting concentration by vial strength and diluent volume. Arithmetic only, provided for laboratory preparation and dilution planning — this is not dosing guidance. The method is set out in the reconstitution and dilution guide.
| Vial | +1 mL | +2 mL | +3 mL | +5 mL |
|---|---|---|---|---|
| 50 mg | 50.00 mg/mL | 25.00 mg/mL | 16.67 mg/mL | 10.00 mg/mL |
| 100 mg | 100.00 mg/mL | 50.00 mg/mL | 33.33 mg/mL | 20.00 mg/mL |
Molar reference
Molar quantity per vial at each available strength, calculated from a molecular weight of 400.90 g/mol. Useful where a protocol is specified in molar rather than mass terms. Values are for the free peptide; net peptide content per vial depends on water and counter-ion content stated on the certificate of analysis.
| Vial | Micromoles | Nanomoles |
|---|---|---|
| 50 mg | 124.719 µmol | 124719 nmol |
| 100 mg | 249.439 µmol | 249439 nmol |

Storage and handling
Copper-complexed peptides are supplied as the coloured complex and will produce a blue to blue-green solution on reconstitution. Colour intensity varies between lots with copper loading and is not by itself an indicator of purity. Avoid contact with chelating agents and reducing agents, which can strip the copper from the complex.
- Lyophilised powder: store sealed at −20 °C, protected from light and moisture.
- Bring sealed vials to room temperature before opening, so warm air does not condense moisture onto cold powder.
- Reconstitute with bacteriostatic water directed against the vial wall; do not shake or vortex. Swirl gently until dissolved.
- After reconstitution: store at 2–8 °C and use within the working period established by your laboratory.
- Avoid repeated freeze–thaw cycles. Aliquot where the solution will be accessed repeatedly.

Documentation
A certificate of analysis is available by request for the batch supplied, covering HPLC purity and mass-spectrometry identity confirmation. The two measurements answer different questions — identity confirms the molecule, purity quantifies how much of the sample it represents. See what each one proves.
Frequently asked
What specifications of GHK-Cu are available?
GHK-Cu is listed in 3 specifications: 100 mg x 1 vial, 50 mg x 10 vials, 100 mg x 10 vials. Prices are in USD and include the vial.
Is a certificate of analysis available for GHK-Cu?
Yes. A certificate of analysis is available by request for the batch supplied, covering HPLC purity and mass-spectrometry identity confirmation. Request the COA for a specific lot before ordering if your protocol requires documentation on file.
Why does the solution turn blue, and does colour indicate purity?
Copper-complexed peptides are supplied as the coloured complex and produce a blue to blue-green solution on reconstitution. Colour intensity varies between lots with copper loading and is not by itself an indicator of purity — the certificate of analysis is. Avoid chelating and reducing agents, which can strip copper from the complex.
How should GHK-Cu be stored?
Store the lyophilised powder sealed at −20 °C, protected from light and moisture. After reconstitution, store at 2–8 °C and avoid repeated freeze–thaw cycles. Bring sealed vials to room temperature before opening to avoid condensation onto cold powder.
What does shipping cost?
Carts made up entirely of single vials ship for $20.00. Any cart containing a multi-vial kit ships for $60.00 standard or $80.00 expedited, with single vials included free. From 4 kits upward the rate drops to $30.00 standard or $50.00 expedited. Shipping is added at checkout and revalidated on the server before the order is accepted.
How is payment handled?
Payment is accepted in on-chain Bitcoin or USDT on Ethereum (ERC-20). No card details are collected. Orders remain pending until the payment is verified on-chain, after which a confirmation is sent.
