About GHK-CU
GHK-Cu 100mg is a copper-chelating tripeptide (Gly-His-Lys-Cu) supplied as a lyophilized research reference standard. Characterized by its metal-ion coordination chemistry and peptide-metal binding properties. Supplied for in-vitro binding assays, metalloprotein interaction studies, and analytical method development. Not for use in any living organism.
Each vial is produced under rigorous quality controls to support consistent and reliable experimental results.
Product Specifications
• Form: Lyophilized powder
• Content: 100mg per vial

Why buy from us
Every vial of GHK-CU we ship is backed by third-party analytical testing and a certificate of analysis you can read before you order. We focus on a short list of research compounds so each one gets the attention it needs.
- Third-party verified. Each batch is tested by an independent laboratory for purity and identity.
- Published COAs. The report for the current batch is linked on this page.
- Consistent supply. Lyophilized, sealed and labeled with batch information for traceability.
- Real support. Questions about an order or a document? Our team answers from Charleston, SC.
Storage
Before reconstitution
Store the lyophilized powder at or below 8 °C in a dry place, away from light. For long-term storage, keep it frozen at −20 °C.
After reconstitution
Refrigerate at 2–8 °C and use within 30 days. For longer preservation, aliquot and freeze at −20 °C, and avoid repeated freeze–thaw cycles.
Shipping
Orders ship from Charleston, SC with tracking on every package. Vials are packed to protect them in transit, and you can check estimated delivery times for your state on the shop page.

Frequently Asked Questions
1. Is GHK-CU supplied as a lyophilized powder?
Yes. GHK-CU ships as a lyophilized (freeze-dried) powder, which removes moisture and helps keep the compound stable until it is reconstituted for research.
2. How is the purity of GHK-CU verified?
Each batch is tested by an independent laboratory using HPLC for purity and mass spectrometry for identity. The certificate of analysis for the current batch is linked on this page.
3. What does 99%+ HPLC purity mean?
High-performance liquid chromatography separates a sample into its components. A 99%+ result means the target compound makes up at least that percentage of the measured sample.
4. How should GHK-CU be stored before reconstitution?
Keep the sealed vial at or below 8 °C in a dry place, away from light. For long-term storage, keep it frozen at −20 °C.
5. How long is GHK-CU stable after reconstitution?
Refrigerated at 2–8 °C, use within 30 days. For longer preservation, aliquot and freeze at −20 °C and avoid repeated freeze–thaw cycles.
6. Can I see the COA before I order?
Yes. The full COA is available to download in the Certificate of Analysis section above, and on our COA page.
7. Is GHK-CU intended for human use?
No. GHK-CU is sold for laboratory research use only. It is not for human or veterinary consumption, and we do not provide dosage or administration guidance.
8. Where do orders ship from?
All orders ship from Charleston, SC with tracking.
