GHK-Cu
Copper tripeptide complex · cellular and structural research materials
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (GHK) — a naturally occurring copper-binding peptide. It is supplied as a lyophilized powder, characteristically blue-tinted from the bound copper.
Research context
In published literature, GHK-Cu is studied in the context of copper-transport, extracellular-matrix, and skin/collagen research using in-vitro and cosmetic-science research models. Glow Peptides supplies GHK-Cu strictly as a reference material for such in-vitro and preclinical research. It is not a therapeutic product and is not for human or veterinary use.
Handling & storage
GHK-Cu is supplied lyophilized (freeze-dried). General laboratory handling practice for research materials of this type:
- Sealed vials: store lyophilized powder cold and away from light; long-term storage is typically in a freezer. Sealed, dry vials are stable far longer than reconstituted material.
- Reconstitution: research protocols typically reconstitute with bacteriostatic or sterile water introduced slowly against the vial wall, swirled (not shaken) until dissolved. See our reconstitution & storage guide.
- After reconstitution: keep refrigerated and protected from light; material in solution is less stable than the dry powder.
- Documentation: record the lot number and its Certificate of Analysis for your records.
Quality & testing
Every lot of GHK-Cu we supply is independently tested at a U.S. laboratory and ships with a lot-specific Certificate of Analysis. Testing includes HPLC with UV detection for purity and mass spectrometry for identity, with our purity standard at ≥99%.
You can search any lot and view its documentation on our Quality & COA verification page, and learn what the numbers mean in how to read a Certificate of Analysis. Our published customer rating is 4.5 on Trustpilot.
GHK-Cu is available as an independently tested, ≥99%-purity research reference material with a per-lot Certificate of Analysis.

Is GHK-Cu intended for human use?
No. GHK-Cu is supplied strictly as a reference material for in-vitro laboratory and preclinical research. It is not a drug or supplement and is not for human or veterinary use.
How is GHK-Cu tested for purity?
Each lot is independently tested at a U.S. laboratory by HPLC with UV detection (purity) and mass spectrometry (identity), and ships with a lot-specific Certificate of Analysis. Our purity standard is ≥99%.
How should GHK-Cu be stored?
Sealed lyophilized vials are stored cold and away from light, typically frozen for long-term storage. Once reconstituted for research, material is kept refrigerated and protected from light.
