GHK-Cu

GHK-Cu peptide (Copper Tripeptide-1): Neurogen Research’s copper peptide for Australia and New Zealand

Copper gives GHK-Cu both its name and its character. The compound pairs a tiny peptide, glycine-histidine-lysine (GHK), with a copper atom, and that copper is why it is also written as Copper Tripeptide-1 (“Cu” being the symbol for copper). Neurogen Research stocks the GHK-Cu peptide for Australian and New Zealand laboratories as a freeze-dried powder, filed under Recovery and Repair, and supplied for in-vitro (test-tube) research only, not for use in people or animals.

Key points on the GHK-Cu peptide

• The compound: a copper peptide, the GHK tripeptide bound to copper; also known as Copper Tripeptide-1.
• Purity: latest COA 99.410% by HPLC (lot CU938), checked by the independent lab Janoshik.
• Options: 50mg and 100mg vials, $89 to $179, sold alone or paired with a starter kit.

What GHK-Cu is made of

GHK-Cu has two working parts. The first is GHK, a tiny peptide of three amino acids (the building blocks glycine, histidine and lysine) joined in one set order. The second is a copper atom that the peptide holds onto. This pairing is what a chemist calls a copper complex; it is lab-made (synthetic), not a steroid, and the copper is what gives the powder its unusual blue-to-purple colour. On its own the peptide is written GHK; once copper is attached it becomes GHK-Cu, the copper-bound form that nearly all copper-peptide research uses.

How GHK-Cu is used in laboratory studies

In the lab, GHK-Cu acts as a standard copper peptide for cell and tissue experiments. Researchers look at how it relates to collagen (the protein that holds skin and connective tissue together), how skin cells kept in culture (dermal fibroblasts) react to it, changes in gene activity, and its part in how cells manage certain harmful molecules (antioxidant pathways). All of this sits firmly in-vitro, in cells and tissue, and describes no effect in a living body.

Comparing GHK-Cu with related copper and repair peptides

Within the Neurogen Research recovery and repair line, GHK-Cu is usually studied alongside a few relatives. The nearest is AHK-Cu, a second copper peptide that differs by just one amino acid, which makes it the obvious partner for copper-to-copper comparisons. Researchers also set GHK-Cu against broader repair peptides such as BPC-157 and TB-500. All of these are in-vitro comparisons, a routine way to see how the compounds differ.

GHK-Cu purity and third-party testing

Purity is the headline figure for a research peptide, so Neurogen Research has every batch of GHK-Cu analysed by Janoshik, an independent outside lab. The method is HPLC (high-performance liquid chromatography, which separates a sample to read how much of it is the target compound), and the latest COA reads 99.410% (lot CU938). We post each batch’s Certificate of Analysis (CoA, the signed lab result) on our certificate page so you can match it to the vial you receive.

GHK-Cu is for laboratory research only

GHK-Cu shows up as a skincare ingredient in other markets, but the vial sold here is nothing of that kind. This is strictly bench material. It holds no registration with the TGA (Australia’s medicines authority, the Therapeutic Goods Administration), or any comparable overseas regulator, for application to or inside the body, and none of the wording on this page should be read as medical or cosmetic guidance. Neurogen Research releases it only to qualified researchers equipped to handle it under correct laboratory conditions and in keeping with every applicable Australian and New Zealand law.

Buy GHK-Cu peptide in Australia and New Zealand

• Buy the GHK-Cu peptide online from Neurogen Research, an Australian-owned supplier holding stock onshore, with 50mg and 100mg vials priced between $89 and $179.
• New to copper-peptide prep? Add the Starter Kit to your vial for the core reconstitution supplies in one go.
• Order before 12pm AEST for same-business-day dispatch out of Sydney by tracked Australia Post Express. Metro Australia usually arrives in 2 to 4 business days, regional in 3 to 5, WA in 4 to 6, and New Zealand in 4 to 6.
• Clear $200 for free express shipping (a flat $14.95 applies below that), and a batch Certificate of Analysis comes with every order.

Storing and preparing GHK-Cu

• Keep the sealed vial cool, dry and dark, below 25°C; for the long term, store it near -20°C in a freezer.
• To reconstitute (bring the powder back to a liquid), run bacteriostatic water (sterile water carrying a mild preservative that holds bacteria back) gently down the inside of the vial.
• Refrigerate the solution once mixed, finish it within a few weeks, and limit freeze-thaw cycles, which can wear the peptide down.
• A blue-to-purple solution is normal; discard a vial that turns cloudy or carries particles.

GHK-Cu specifications

Common questions about GHK-Cu

What is the GHK-Cu peptide?

It is a copper peptide, a short chain of three building blocks (amino acids) joined to copper. Copper Tripeptide-1 is just another name for it. Neurogen Research sells it as a freeze-dried (dried into a powder) material for test-tube (in-vitro) research.

What is GHK-Cu used for in research?

In the lab it is used as a standard copper peptide. Researchers study things like collagen (a protein found in skin and connective tissue) and how skin cells grown in a dish respond to it. This is test-tube work only, not for use in people or animals.

What is the difference between GHK-Cu and GHK?

Plain GHK is the peptide by itself, carrying no copper. GHK-Cu is that same peptide once a copper atom is attached. Copper is the main reason this form exists, and most copper-peptide research uses GHK-Cu, not plain GHK.

Why is GHK-Cu blue or purple?

The colour comes from the copper the peptide holds. Most peptides are white, but GHK-Cu is coloured because of its copper, and that blue-to-purple shade is normal, not a fault.

How pure is Neurogen Research GHK-Cu, and do I get a CoA?

Janoshik, an independent lab, measured the most recent batch at 99.41%, above the 99% mark. Its signed Certificate of Analysis (CoA) sits on our certificate page and is included in the box you receive.

How is GHK-Cu stored and reconstituted?

Hold the sealed vial somewhere cool, dry and dark under 25°C, and move it to a freezer near -20°C for the long term. To make it up, add bacteriostatic water to the powder, keep the mixed liquid cold in a fridge, and avoid freezing and thawing it over and over.

What sizes and price does GHK-Cu come in?

Neurogen Research offers two vial sizes, a 50mg and a 100mg, each priced between $89 and $179, and you can take a vial by itself or paired with a starter kit.

Where can I buy GHK-Cu peptide in Australia and New Zealand?

Order online from Neurogen Research. We hold stock in Australia and deliver to both Australia and New Zealand, so a shop visit or a “near me” search is not needed.

Is GHK-Cu approved for human, cosmetic or medical use?

No. On this page GHK-Cu is treated purely as research material for the lab. It is not sold as a medicine, skincare or a supplement, and it must never go on or into people or animals.

Disclaimer: Neurogen Research supplies GHK-Cu for in-vitro laboratory research only. It is not a medicine, a cosmetic, a supplement or a skincare product, and it is not for use on or in humans or animals. By ordering, you confirm that you are a qualified researcher and that you will store, handle and use it in line with all applicable Australian and New Zealand laws.
