GHK-Cu Wholesale: A Sourcing Guide for Research Suppliers

What GHK-Cu Is, on Paper

GHK-Cu is listed as the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine. It is also catalogued as prezatide copper, copper tripeptide-1 and GHK copper. A supplier's product page should give its identity data and cite the source. Our GHK-Cu wholesale page lists CAS 89030-95-5, the formula C14H23CuN6O4+ and a molecular weight of 402.92 g/mol, from PubChem, which gives the formula and weight of the copper complex as a cation.

Some of those synonyms come from other industries. In a research catalog, use the name and the identity data, and describe the material, never what it does. See writing storefront copy for research-use-only products.

GHK and GHK-Cu Are Not the Same Material

The tripeptide GHK on its own, without copper, is a different material with different identity data: a different formula, a different molecular weight and a different mass on an identity test. Suppliers don't always label the difference clearly. Check that the quote, the vial label and the report all name the copper complex, and that the identity result on the report matches GHK-Cu.

When a supplier lists both, ask which one the quoted lot is. A name on a label is a claim; the measured mass on the report is the evidence.

Reading the Formula and Weight

The identity data for GHK-Cu can look unusual next to a plain peptide. The formula C14H23CuN6O4+ includes copper and ends in a plus sign because PubChem records the copper complex as a cation. Another source may present the complex differently, for example with a counter-ion included, and so give a different formula or weight for what is described as the same material.

That doesn't make either source wrong, but it does mean you should compare like with like. When two suppliers quote different molecular weights for GHK-Cu, ask each which form the figure describes and which source it comes from. Keep the source you rely on cited on your own product page, as ours cites PubChem.

Sizes, Form and Blends

GHK-Cu is usually supplied as lyophilized powder in single vials. We list it in a 50 mg vial, a larger amount per vial than many single peptides, so check that the quote, the label and the report state the same labelled size. Ask about other sizes or a larger factory-direct run if you need one.

It also appears in multi-peptide blends. Our GLOW blend lists GHK-Cu with BPC-157 and TB-500, and KLOW adds KPV to those three. Each composition is on the product page. A blend report usually gives an average purity across its components rather than one figure per compound, so read which it is. See the blends class.

Single Compound or Blend: Documentation Differs

If you plan to carry both GHK-Cu on its own and a blend that contains it, treat them as separate products in your records. The report for the single compound covers that vial only; it doesn't document the GHK-Cu inside a blend, and a blend report doesn't document a single-compound vial.

• Separate SKUs. One for GHK-Cu, one for each blend such as GLOW or KLOW.
• Separate reports. Each product page links its own report, for its own labelled size.
• Separate labels. A blend label lists every component and its labelled amount, as on the product page.
• Read the purity line. A blend figure may be an average across components. How peptide blend reports work covers the difference.

What the Report Should Show

The report published for our GHK-Cu is on its product page, linked to the laboratory's own document. How to verify a peptide COA with the laboratory shows how to check one.

• The product and labelled size, matching what you're buying.
• A batch or lot number, the same one printed on your vials.
• HPLC purity, with the method and the wavelength.
• Identity by mass spectrometry (LC-MS), confirming the measured mass matches GHK-Cu.
• Net content, if the laboratory measured it: the amount found in the vial, set against the labelled size.
• The laboratory's name and a way to verify the report with them.

Research Publication Statistics

Our GHK-Cu research statistics page shows how much has been published, by year and study type, with the PubMed search shown so you can repeat it. It is a view of the literature for catalog planning, not a description of the material or of anything it does. The research hub lists the other compounds with a statistics page.

Questions to Ask Any GHK-Cu Supplier

• Is the quoted lot the copper complex, and does the identity result on its report match GHK-Cu?
• Which source does your formula and molecular weight come from, and which form does it describe?
• Which lot will I receive, and can I see its report before I pay?
• Does the labelled size mean powder weight or GHK-Cu weight?
• For a blend, is the purity per component or averaged?
• How long does the quoted price hold, and what is the quoted lead time?

Comparing Quotes and Getting Ours

Compare quotes for the same size, vial count and documents: the lot and its report, labels, shipping and how long the price holds. Our wholesale stock ships from Tampa Bay, Florida, to the United States, factory-direct orders can ship internationally, and every wholesale lot comes with a certificate of analysis. We don't publish a minimum order.

To get pricing, add GHK-Cu to your list in the catalog and send it on WhatsApp or by email. The quote names the lot and its report. GHK-Cu sits in our peptides class, and if you need a compound we don't list, ask in the same message: we source beyond the catalog. For your own label on the vials, see white label.

A quote that names the tripeptide without copper, or gives no CAS number at all, is not comparable with one for the copper complex, however close the prices look. Ask each supplier to state the compound, the CAS number and the lot in writing before you compare.

When the order arrives, check that every vial shows the lot named on your quote and that its report names the same product and size before the units go into stock. Keep the lot number, the report and the order together in your records, so a buyer who asks which batch they received gets an answer without a search.
