Description
GHK-Cu RAW is the loose-powder form of the copper tripeptide GHK-Cu, supplied by weight for laboratories that prepare, blend or repackage their own research formulations.
Used as starting material for skin-biology, collagen-expression and gene-expression research preparations. Identity and purity are lot-tested before release and the lot COA is available on request.

Quality and testing
Quality assurance is documented for every batch. Every batch of GHK-Cu Raw Powder is tested by HPLC against a ≥99% purity release specification and by mass spectrometry to confirm the molecular identity matches the labelled compound. The batch Certificate of Analysis is published in the test-results library (/test-results/) — the batch number printed on the vial label may be entered there to retrieve the results for that exact batch. In the event that no result is returned, the support team should be contacted via the contact page (/contact-us/) before the product is used, and the discrepancy will be resolved.
This documentation is material to reproducibility. Within the research-peptide market, an identical compound name does not guarantee identical material: synthesis impurities, truncated sequences and degraded stock are not detectable by visual inspection, yet each is identified by an HPLC trace. The release process exists to ensure that the compound recorded in a protocol corresponds to the compound described in the literature being replicated. A full explanation of chromatogram and mass-spectrometry data on a supplier certificate is provided in the guide: How to Read a Peptide Certificate of Analysis (COA) (/blog/how-to-read-a-peptide-coa/).
Why laboratories source GHK-Cu Raw Powder from Champion Peptides Lab
- Batch-matched documentation. The Certificate of Analysis available at the time of ordering corresponds to the batch dispatched, and the same document is verifiable against the vial upon delivery. Batch numbers are printed on every label and are searchable in the test-results library (/test-results/).
- Complete published specifications. CAS number (where assigned), sequence or composition, molecular weight, form and storage are listed on this page and in the accompanying order documentation — the details required for protocols, publications and audits. Should any specification be absent, it will be provided from the batch documentation upon request via the contact page (/contact-us/).
- Cold-chain, sealed, tracked dispatch. Lyophilised compounds are vacuum-sealed and stored at −20°C until dispatch, then shipped in discreet, tracked packaging. Every order includes Shipping Protection by default.
- Technical and order support. Questions concerning products, documentation, availability and shipping are answered by a support team that works with these compounds daily — Monday to Friday, 9:00 AM–5:00 PM MST. Advice on protocols or applications is outside the scope of support services. This boundary is deliberate, and it is part of the basis on which laboratories rely upon the documentation provided.
Storage and handling
Store sealed vials in a freezer at −20°C, protected from light and moisture.
Ordering and delivery — Europe & USA
Orders placed before 12:00 PM MST are dispatched the same business day in discreet, tracked packaging. Delivery within the USA typically takes 2–5 business days. Delivery to Germany, France, Spain, the Netherlands, Italy, Poland, the UK and most of the EU typically takes 5–10 business days — see the country table and customs notes on the Shipping to Europe (/shipping-to-europe/) page. Every order includes Shipping Protection by default, and multi-vial packs (10, 15 and 20 vials where offered) reduce the per-vial cost for extended studies.
Documenting this compound
For laboratory records, cite the compound as: GHK-Cu Raw Powder (CAS 49557-75-7 (GHK)), supplied as lyophilised (freeze-dried) powder, vacuum-sealed vial, purity ≥99% by HPLC with mass-spectrometry identity confirmation, batch number as printed on the vial. The batch COA in the test-results library (/test-results/) is the supporting document for that citation. Storage conditions for your materials log: sealed at −20°C, protected from light; reconstituted at 2–8°C.
Frequently asked questions
What purity is guaranteed for this GHK-Cu Raw Powder?
