GHK-Cu for Sale
The gold standard in skin, collagen and hair research.
From $34.99 30% off
GHK-Cu is a naturally occurring copper tripeptide studied for its role in skin remodeling, collagen and elastin signaling, and tissue repair. Its declining levels with age have made it one of the most researched compounds in the beauty and longevity space.
Buy GHK-Cu online from Healio. GHK-Cu for sale, also known as copper peptide, comes as 50mg and 100mg vials, supplied as a research peptide for laboratory use only and shipped from the USA with the batch certificate of analysis published before you order.
What is GHK-Cu?
GHK-Cu is a copper peptide complex: the tripeptide glycine-histidine-lysine bound to a copper ion. It occurs naturally in human plasma, and plasma concentrations decline substantially with age, which is the observation that made it interesting to researchers in the first place.
The copper is not incidental. The complex carries the biological activity studied in the literature, and the peptide without its copper ion behaves differently. Any GHK-Cu for sale should be verified as the copper-bound complex rather than the bare tripeptide.
GHK-Cu research applications
This compound has the deepest published literature of anything in the skin and repair category, running back to the 1970s. Research covers collagen and elastin synthesis in fibroblasts, wound repair signalling, antioxidant and anti-inflammatory activity, and hair follicle signalling.
Notably, much of the foundational work came out of wound healing research rather than cosmetics. The skin appearance angle arrived later, downstream of studies that were originally about tissue repair.
How GHK-Cu works
The research describes GHK-Cu acting as a signalling molecule that influences gene expression related to tissue remodelling, alongside a role in copper transport. Copper is a required cofactor for lysyl oxidase, an enzyme involved in crosslinking collagen and elastin, which connects the copper-carrying function directly to the structural findings.
It is also visibly blue at meaningful concentrations. A colourless product claiming copper peptides is worth a second look.
Research grade GHK-Cu vs cosmetic copper peptide serums
These are different products answering different questions. A cosmetic serum must be shelf-stable for years and pass regulatory requirements for leave-on products, which pushes formulations toward low active concentrations. Research-grade GHK-Cu is supplied as a lyophilized powder of stated purity with a certificate, because a laboratory needs to know the quantity it is working with.
The difference is not potency exactly. It is whether anyone can tell you what you have. copper peptides for skin covers the concentration question in detail.
GHK-Cu reconstitution and handling
Supplied lyophilized. Reconstitute with bacteriostatic water, adding diluent slowly against the vial wall and allowing the powder to dissolve without agitation. Bacteriostatic water is available separately. The GHK-Cu calculator turns vial strength and water volume into a concentration.
GHK-Cu storage and stability
Store sealed lyophilized vials at minus 20 degrees Celsius, protected from light. Copper complexes are light-sensitive, so protection from light matters more here than for some other compounds. Reconstituted solution requires refrigeration and a shorter window.
GHK-Cu price
GHK-Cu comes in 2 sizes. Ordering more than one vial lowers the price of every vial in the order. The table shows the GHK-Cu price per vial and per mg for every size. That GHK-Cu cost is the price per vial before shipping. For the best price per vial on GHK-Cu, order three or more.

Where to buy GHK-Cu in the US
Where to buy GHK-Cu peptide matters more than the price, because a vial is only worth what its testing is worth. Five checks separate a reliable US vendor from a reseller, and this is how Healio meets each one.
- A certificate of analysis for the exact batch. The GHK-Cu report for batch HEALIO-GHKCU01 is published before you order, not emailed after you have paid.
- Testing by a lab that is not the seller. The report comes from Quantum Life Sciences in Portland, Maine, an independent laboratory, and carries its own certificate number.
- Identity as well as purity. HPLC measures how pure the powder is. Mass spectrometry (ESI-MS) confirms that it is GHK-Cu in the first place. A report with only one of the two is half a report.
- A lot number you can trace. The lot number on your vial ties to its own report, so you can check the document against the product in your hands.
- US dispatch and plain terms. Orders ship from the United States, and the shipping and returns policy is public before you buy.

GHK-Cu lab results
The current GHK-Cu batch was tested on 23 June 2026 by Quantum Life Sciences. The certificate covers the 50 mg vial. Purity is measured by HPLC and identity is confirmed by mass spectrometry. The summary below is taken from the certificate of analysis. Reading the GHK-Cu COA takes a minute: purity by HPLC, identity by mass spectrometry and endotoxins are in the first rows.
| Batch | HEALIO-GHKCU01 |
|---|---|
| Lot number | GHKCU-260618-01 |
| Purity (HPLC) | 99.4% (specification 98.0% or higher) |
| Identity (ESI-MS) | Confirmed, conforms to the reference standard (403.93) |
| Mass found | 50.42 mg (labeled 50 mg) |
| Endotoxins (LAL) | Under 0.05 EU/mg (limit 5 EU/mg) |
GHK-Cu reviews: is Healio a legit GHK-Cu source?
Searching for GHK-Cu reviews, or asking whether Healio is a legit GHK-Cu source? The useful evidence is what you can check yourself, because reviews only help if you can check them.
- Match the lot number on your vial to the GHK-Cu certificate of analysis.
- Look up the testing laboratory named on the certificate and confirm it is not Healio.
- Read how the content on this site is written and checked on the editorial standards page.
- If a seller will not publish a batch report for the product you are buying, treat that as your answer.

GHK-Cu FAQ
Where can I buy GHK-Cu in the US?
Healio sells GHK-Cu direct from the United States, with the batch certificate of analysis published before you order. It is supplied for laboratory research use only.
How much does GHK-Cu cost?
GHK-Cu prices are: 50mg is $34.99, about $0.70 per mg; 100mg is $44.99, about $0.45 per mg. Ordering two vials of the same size takes 5% off each, and three or more takes 10% off each. Shipping is free on orders over $185.
Is Healio GHK-Cu third-party tested?
Yes. Each batch is tested by an independent US laboratory for purity by HPLC and for identity by mass spectrometry. The current batch measured 99.4% purity with identity confirmed, and the full report is on the GHK-Cu COA page.
How fast does GHK-Cu ship?
Weekday orders placed before 2:00 PM ET usually ship the same business day. Standard ground is $14.99 and free over $185, 2-Day Air is $23.99 and Next Day Air is $54.99. Delivery times are carrier estimates and are not guaranteed.
What payment methods does Healio accept?
Credit and debit cards, paid at checkout.
How do I reconstitute GHK-Cu?
Lyophilized GHK-Cu is reconstituted with bacteriostatic water. The GHK-Cu calculator converts vial strength and water volume into concentration and syringe units. It is arithmetic only and does not recommend an amount.
Is GHK-Cu for human use?
No. Healio supplies GHK-Cu strictly for laboratory research. It is not for human or veterinary use, and it is not a drug, supplement, food or cosmetic.
What is GHK-Cu used for in research?
Collagen and elastin synthesis studies, wound repair research, antioxidant signalling and hair follicle work. Supplied as a laboratory research material only.
What does GHK-Cu do for skin in the research?
Published work examines stimulation of collagen and elastin production in fibroblasts, alongside wound repair signalling. A large share of that research is in cell culture rather than human trials, which is worth keeping in mind when reading stronger claims.
Is GHK-Cu the same as copper peptides in skincare?
It is the same molecule, at very different concentrations and in a very different format. Cosmetic formulations are constrained by shelf stability and regulatory requirements for leave-on products.
