What Is GHK-Cu Copper Peptide?
GHK-Cu, also known as Copper Tripeptide-1, is a copper-complexed tripeptide formed from glycyl-L-histidyl-L-lysine (GHK) and copper. In cosmetic raw materials, it is commonly supplied as a blue to blue-purple powder for use in skincare and personal care formulations.
For cosmetic manufacturers and ingredient buyers, GHK-Cu should be evaluated beyond the product name. Key specifications include purity, identity, assay method, copper content, solubility, pH and microbiological quality. Batch-specific COA and analytical data are important for confirming that the material meets the required formulation and quality specifications.

GHK-Cu Formulation Considerations
When formulating with GHK-Cu Copper Peptide, the following points are worth considering:
1. pH
A mildly acidic to neutral formulation is generally preferred. Avoid conditions that may affect copper-peptide stability.
2. Chelating Agents
Check the use of strong chelating agents such as EDTA, as they may interact with copper ions.
3. Addition Temperature
For water-based formulations, add GHK-Cu during the appropriate low-temperature stage and avoid unnecessary heat exposure.
4. Water Solubility
GHK-Cu is water-soluble and can be incorporated into the aqueous phase of suitable formulations.
| Ingredient | Common Combinations | Formulation Considerations |
|---|---|---|
| Hyaluronic Acid | Sodium Hyaluronate, Hydrolyzed HA | pH, viscosity |
| PDRN | PDRN, Sodium DNA | pH, compatibility |
| Panthenol | D-Panthenol | pH, water-based systems |
| Niacinamide | Niacinamide | Final pH, formulation stability |

FAQs
1. What should I check when evaluating a GHK-Cu supplier?
For GHK-Cu, buyers should look beyond the stated purity and review the specified grade, HPLC test results, batch COA and relevant quality parameters. The supplied material should match the specification required for the intended cosmetic formulation.
2. Can I evaluate GHK-Cu before placing a bulk order?
Yes. 10–50g samples are available for formulation evaluation. Buyers can test the material in their own formulation system before moving to a larger trial or commercial quantity.
3. Is the 99% GHK-Cu specification HPLC tested?
Yes. The specified GHK-Cu content is tested by HPLC, with analytical information available for the corresponding batch. This allows the stated specification to be checked against actual test results.
4. Can GHK-Cu be supplied to a specific formulation requirement?
Yes. GHK-Cu can be discussed according to the required purity, application, quantity and packaging. Customized specifications may be available for projects with specific technical requirements.
5. What quantity should I order for an initial evaluation?
A 100g trial MOQ is available for customers who need more than a laboratory sample but are not yet ready for bulk purchasing. Larger quantities can be arranged after the material has been evaluated and the required specification confirmed.
