Storage & handling: Store at 2–8 °C (≤ –20 °C long-term), away from light. Ships at ambient temperature.
How we test
Certificates are issued by independent labs. Identity and purity are measured by LC-MS; endotoxin, where listed, by a LAL screen. The latest report for this option: Endotoxin tested, lot 395390, tested 30 Mar 2026.
How to read your COA
Start with the lot number on the report. Identity confirms by mass spectrometry that the molecule is the one on the label. Purity is the share of the sample that is the target peptide, measured by LC-MS. Endotoxin, where tested, is screened by LAL and must sit below 0.5 EU/mL. The lab name and test date show who ran it and when.

Research-grade copper-coordinated tripeptide complex supplied in a format for controlled in vitro investigation of metal-binding peptide chemistry and extracellular signaling pathway models.
Product overview
GHK-Cu (100mg) is a copper–tripeptide complex supplied for laboratory research. The compound consists of a defined tripeptide sequence coordinated with a copper (II) ion and is studied in biochemical and cell-based signaling models.
The presentation is intended for research programs requiring larger material allocation for extended assay series, method development, or multi-run experimental workflows. Each batch is accompanied by Certificate of Analysis (COA) documentation verifying molecular identity and analytical purity.
This product is supplied exclusively for research use in qualified laboratory environments.
Research focus
GHK-Cu appears in published in vitro research examining copper-binding peptide behavior and pathway-level signaling dynamics in controlled experimental systems.
Common research contexts include:
- copper coordination chemistry and peptide–metal interaction models
- extracellular matrix (ECM) signaling pathway assays
- matrix metalloproteinase (MMP) and TIMP profiling in fibroblast systems
- TGF-beta–associated signaling readouts in cell line preparations
- oxidative stress and redox marker quantification in controlled cell models
All references describe mechanistic research endpoints and do not imply organism-level outcomes.
Methodological notes
GHK-Cu is supplied as a lyophilized powder.
Recommended handling practices:
- store sealed in a cool, dry, light-protected environment
- prevent exposure to moisture and elevated temperatures
- reconstitute using sterile laboratory techniques and validated solvents
- prepare aliquots where appropriate to minimize freeze–thaw cycles
- handle exclusively in controlled laboratory environments by trained personnel
All procedures should follow institutional laboratory protocols.
Quality & sourcing
Each batch undergoes analytical verification and is supplied with supporting documentation, including:
- liquid chromatography-mass spectrometry (LC-MS) purity testing
- mass spectrometry molecular identity confirmation
- batch traceability documentation
- Certificate of Analysis (COA) for each lot
Endotoxin testing (LAL method) is available upon request for cell-based research applications.

Researchers often ask
Is GHK-Cu for human use?
No. GHK-Cu is sold for laboratory research only. It is not for human or veterinary use, and it is not a drug, food or cosmetic.
How do I find the lab report?
Use View COAs on the product page, or search the COA library by compound name. The summary is public; the signed PDF reports are available to signed-in researchers.
Why is purity measured by LC-MS?
LC-MS separates the sample and identifies each component by its mass, so one run confirms identity and measures purity.
When will my order ship?
Orders are dispatched within 24–48 business hours. Regular tracked delivery takes 5 to 10 days and express tracked 3 to 5 days. Regular shipping is free on orders over $200 and express on orders over $400, after discounts.
