What GHK-Cu is

GHK-Cu is a complex of copper with the three-amino-acid peptide glycyl-L-histidyl-L-lysine (GHK), a molecule first found in human blood plasma in the 1970s. It is best known as a skin-care ingredient and has been studied mainly in cell culture and animal wound models, with a handful of small human trials of topical products. Injected GHK-Cu has no published human trial data. Read the full GHK-Cu guide, with the published research and references.

Before you choose a GHK-Cu supplier

Price per mg is only half the comparison. Check that the supplier publishes a certificate of analysis for the batch it is selling, ideally from an independent laboratory, and that the certificate confirms identity as well as purity: our guide on how to read a COA shows what to look for. A price far below the rest of the list is more often a warning than a bargain; peptide prices explained sets out why.

For what GHK-Cu is and what published studies have found, see our GHK-Cu guide. Handling questions are covered in how to store peptides, and the peptide calculator converts a vial size and water volume into concentration and syringe units. Rules on buying and importing differ by country: read are peptides legal in the US? and see all suppliers serving the US.

Checking a GHK-Cu certificate of analysis

  1. The certificate names a laboratory you can find independently, and ideally one with no stake in the result.
  2. It carries a batch or lot number that matches the product page or the vial label, and a test date.
  3. It confirms identity by mass spectrometry, not only purity by HPLC. Purity alone does not show the vial contains GHK-Cu.
  4. It includes the chromatogram and mass spectrum, not just a summary table.
  5. Where the laboratory offers online verification of its reports, the report number checks out.

Red flags

  • No certificates at all, or certificates available only “on request”.
  • The same certificate used for several products or several years of stock.
  • Payment only by cryptocurrency or bank transfer, with a discount for paying that way.
  • A price far below every other supplier on this page.
  • No company name, address or way to contact the business other than a web form.
  • Vials labelled only with a code rather than the product name and strength.

How to spot a fake peptide supplier explains each of these in more detail, and third-party peptide testing covers what independent results can and cannot prove.

Vials, capsules and pre-mixed products

Most research peptides are sold as freeze-dried (lyophilised) powder in sealed vials, which is mixed with a diluent such as bacteriostatic water before use in the lab. Some suppliers also sell pre-mixed solutions, nasal sprays or capsules under the same name. These are different products with different stability and dosing, so compare price per mg only between the same form, and check which form a listing is before comparing it with the rest of the table.

GHK-Cu in the US: questions

Where can I buy GHK-Cu in the US?

35 of the suppliers PepFinder tracks list GHK-Cu and are based in or ship to the US. The highest rated are Bluum Peptides, Elite Research Labs, Polaris Peptides. The list on this page is ranked by PepFinder rating, which weighs reliability, delivery, pricing, support and customer reviews; nobody pays to be included or to rank higher.

How much does GHK-Cu cost in the US?

Listed prices in USD run from US$0.03/mg to US$502.50/mg, median US$0.81/mg, across 79 listings from 29 suppliers. Compare price per mg rather than price per vial, and only within one currency; a price far below the rest is more often a warning than a bargain.

What sizes is GHK-Cu sold in?

Suppliers on this page list GHK-Cu in 2mg, 2mg / 1 pack, 2mg x 60, 3mg, 1 x 5mg cartridge, 5mg vial. Most research peptides are sold as freeze-dried powder in sealed vials; capsules, sprays and pre-mixed solutions are different products, so compare price per mg only between the same form.

Is it legal to buy GHK-Cu in the US?

The FDA treats research peptides sold for human use as unapproved new drugs and has said in 2026 warning letters that research-use-only labels do not change that. Our page on whether peptides are legal in the US sets out the rules with a link to every source. This is general information, not legal advice.

Can GHK-Cu be shipped to the US?

The FDA says it is illegal in most circumstances for individuals to import drugs for personal use, and shipments it considers unapproved drugs can be refused entry. Each supplier on this page shows where it is based, so you can see whether an order would cross a border.

How do I check a GHK-Cu supplier's test results?

Ask for a certificate of analysis for the batch being sold, and check that it names the laboratory, the batch number and the test date, and that it confirms identity by mass spectrometry as well as purity by HPLC. PepFinder has not yet collected certificates for GHK-Cu from these suppliers, so check each supplier's own site.

How this list is built: suppliers appear because they list GHK-Cu on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder rating. Prices, sizes and stock are as each site listed them when checked and may have changed. Provisional scores are based on incomplete research.
