What is GHK-Cu?
Copper-binding tripeptide studied in extracellular-matrix and dermal cell models.
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper). It is studied in the context of collagen and extracellular-matrix synthesis, fibroblast activity, antioxidant signalling and copper-dependent gene expression in cellular and preclinical models. Researchers also examine it in dermal cell and wound models. Third-party tested to 99%+ purity and supplied as a lyophilized powder for laboratory reconstitution. For research purposes only, not for human consumption.

How is GHK-Cu stored and handled?
Storage
Store lyophilized vials at -20°C, protected from light. Once reconstituted, refrigerate at 2-8°C and use within the recommended window.
Reconstitution
Use bacteriostatic water; add slowly down the inside wall of the vial. Swirl to dissolve, never shake. See the in-house peptide calculator for concentration (mg/ml) and syringe units (IU on a U-100 syringe).

All research guides- What is GHK-Cu? A Plain Explanation of the Copper PeptideGHK-Cu is the copper complex of the tripeptide glycyl histidyl lysine, a sequence found naturally in human plasma. It is studied in dermal fibroblast, collagen synthesis and matrix remodelling models, where the bound copper ion is treated as part of the active species. It is supplied at high vial mass, so concentration must be recalculated rather than copied from a 10mg peptide.5 min read
- How to Store and Handle Research PeptidesLyophilised research peptides are stored in the refrigerator at 2 to 8 °C, or frozen at -20 °C for longer storage, sealed and protected from light. After reconstitution with [bacteriostatic water](/product/bacteriostatic-water-10ml) the solution is kept refrigerated, never shaken, and never refrozen.5 min read
- How to Read a Peptide COA (Certificate of Analysis)A peptide certificate of analysis shows what an independent laboratory found in one specific batch: identity confirmed by mass spectrometry, purity measured by HPLC, and the measured quantity against the labelled amount. Read it by checking the batch reference against your vial first, then the identity result, then the purity figure and the test date.6 min read

- What your vial should look likeA sealed research peptide vial normally holds a white to off-white lyophilized cake or powder under an intact stopper and crimp cap. Pre-filled pens and nasal spray kits arrive sealed, with their documented appearance on the product page. Appearance never proves identity or purity; the COA for the batch does.4 min read
