About This Compound
What Is GHK-Cu?
GHK-Cu is a naturally occurring tripeptide-copper complex consisting of glycine, histidine, and lysine bound to a copper(II) ion. It was first isolated from human plasma in 1973 by Loren Pickart and is found in plasma, saliva, and urine. GHK levels decline significantly with age, making it a subject of interest in aging and regenerative research.
In preclinical research, GHK-Cu is studied for its role in collagen and elastin synthesis, wound healing, angiogenesis, antioxidant enzyme upregulation, and gene expression modulation. Over 3,000 human genes are reported to be affected by GHK-Cu in laboratory studies.
CoreVionRX doesn’t manufacture peptides. What we do — rigorously — is verify every batch before it reaches our catalog.
≥98%
Purity by Reversed-Phase HPLC
HPLC separates the compound from any impurities and measures the exact purity percentage. The chromatogram is documented on your COA.
MS/MS
Mass Spectrometry Identity Check
Electrospray ionization mass spectrometry verifies the molecular weight matches the compound specification. Confirms you’re getting the actual compound.
Lot #
Lot-Specific Certificate of Analysis
Your COA is tied to your specific production lot — not a generic document. This is not standard practice in this market. We made it one anyway.
100%
Documented Before Listing
No compound reaches our catalog without clearing our verification process first. If documentation isn’t available for a batch, that batch doesn’t ship.

Preclinical Research
What Researchers Study GHK-Cu For
All published research is preclinical — cell cultures and animal models. No human clinical trial data exists for GHK-Cu. Here’s where the science currently stands.
Wound Healing & Collagen Research
GHK-Cu is extensively studied for its stimulatory effects on collagen and elastin synthesis in fibroblast cultures and wound healing models. Research examines accelerated wound closure, tensile strength recovery, and extracellular matrix remodeling.
Pickart L. & Margolina A. (2018) Biomolecules 8(3):55
Antioxidant Pathway Studies
Preclinical research investigates GHK-Cu’s upregulation of superoxide dismutase and catalase — key antioxidant enzymes. Studies examine how copper complexation enables GHK-Cu to modulate oxidative stress in cell culture models.
Buffoni F. et al. (1999) Arch Biochem Biophys 367(2):205-13
Gene Expression Modulation
GHK-Cu is studied as a gene expression modulator. Microarray studies have reported that GHK-Cu affects expression of over 3,000 human genes — including genes related to inflammation resolution, tissue remodeling, and nervous system function.

Why CoreVionRX
Documentation Is the Product.
Most peptide vendors claim purity. We document it. Every compound ships with independent lab verification — not because regulations require it, but because you deserve to know exactly what you’re working with.
Independent HPLC Testing
Every batch runs through reversed-phase HPLC before we list it. The chromatogram appears on your COA. Verify the peak profile yourself.
Lot-Specific Documentation
Your COA is tied to your production lot — not a template document. “COA available upon request” is not how we operate.
Transparent About What We Are
We source and verify. We are not a synthesis lab. That honesty is deliberate — it’s the only way to build a brand worth buying from twice.
Lyophilized for Stability
Ships as lyophilized powder — stable at −20°C for 24+ months. Full integrity maintained until you’re ready to reconstitute.
Common Questions
Straight Answers.
What is GHK-Cu and where does it naturally occur?
GHK-Cu is a naturally occurring tripeptide-copper complex (Gly-His-Lys·Cu²⁺) found in human plasma, saliva, and urine. First isolated in 1973, its plasma concentration declines with age. The research peptide is a synthetic version of this naturally occurring compound.
What research areas use GHK-Cu?
GHK-Cu is studied for collagen and elastin synthesis in fibroblasts, wound healing and tissue remodeling, antioxidant enzyme upregulation, angiogenesis, and broad gene expression modulation. All published research is preclinical.
Why does the GHK-Cu powder appear blue?
The blue coloration is from the copper(II) ion complexed to the tripeptide — this is expected and indicates proper copper coordination. Your COA will document the copper content (typically 14-16% by weight) to verify the complex is correctly formed.
How do I reconstitute GHK-Cu?
Reconstitute with bacteriostatic water or sterile water. GHK-Cu dissolves readily due to its small size and ionic character. The solution will appear light blue. Typical research concentrations: 1–10mg/mL. Use our reconstitution calculator for exact volumes.
How should GHK-Cu be stored?
Store lyophilized at −20°C, protected from light and moisture. Stable for 24+ months. After reconstitution, store at 2–8°C. Avoid excessive light exposure of the reconstituted solution as copper complexes can be photosensitive.
