VitaPep GHK-Cu Copper Peptide Serum is a ready-to-use formula for adults who want a measured, straightforward addition to their skin-care routine. Each 30 mL bottle contains 14 mg of GHK-Cu—also known in cosmetic ingredient language as Copper Tripeptide-1—and is supplied in a prepared format for controlled external application.
Copper Tripeptide-1 is recognized as a skin-conditioning cosmetic ingredient. VitaPep pairs a clearly stated peptide amount with a DMSO-based carrier blend, batch-specific laboratory documentation, and simple directions for topical use. No mixing, reconstitution, or complicated preparation is required.

GHK-Cu is the copper complex of the three-amino-acid peptide glycine-histidine-lysine. In cosmetic ingredient references, Copper Tripeptide-1 is identified as a skin-conditioning ingredient, making it relevant to appearance-focused skin-care routines.
The serum arrives ready to use. There is no powder to mix, no reconstitution step, and no additional preparation beyond cleaning and drying the intended external application area.
Apply only the amount stated in the directions supplied with the current bottle, directly to the intended external area.
Each bottle identifies both the peptide amount and total volume: 14 mg of GHK-Cu in 30 mL. That gives customers a clearer basis for comparing formulas than broad or undefined “copper peptide” claims.
VitaPep publishes the available laboratory documents for batch GHKCU010, including the sample description, testing dates, reported results, and scope of each analysis.
GHK-Cu is a complex formed when copper binds with the tripeptide glycine-histidine-lysine. The name Copper Tripeptide-1 is commonly used for this ingredient on cosmetic labels. It is distinct from uncomplexed GHK, palmitoylated peptides such as Pal-GHK, and unrelated peptides such as BPC-157, TB-500, KPV, or PT-141.
The Cosmetic Ingredient Review identifies Copper Tripeptide-1 as a skin-conditioning cosmetic ingredient. Its assessment concerns the ingredient and the cosmetic-use practices reviewed; it should not be interpreted as a clinical study of this VitaPep finished formula. Review the Cosmetic Ingredient Review assessment.
The named copper-peptide component of the formula. Each 30 mL bottle is labeled to contain 14 mg.
Also known as DMSO, this is listed as 70% of the formula’s carrier blend.
Purified water listed as 30% of the carrier blend.
Always review the ingredient declaration on the current product packaging before use. If the packaging and online listing differ or are unclear, contact VitaPep before applying the product.
GHK-Cu has attracted scientific interest because laboratory researchers have examined its interaction with fibroblasts and extracellular-matrix biology. A cultured-fibroblast study reported increased collagen synthesis under its experimental conditions. Cell-culture findings help explain interest in the ingredient, but they do not establish a visible result from a finished topical product in people. Read the fibroblast study on PubMed.
Human topical evidence remains limited and formulation-specific. In one small randomized study involving skin after CO₂ laser resurfacing, objective evaluation found no significant improvement in wrinkles or overall skin quality from the copper-tripeptide regimen compared with control, although questionnaire responses differed. That product, setting, and application protocol were not the same as VitaPep GHK-Cu Serum. Read the randomized topical study on PubMed.
An in-vitro skin study also evaluated penetration of an aqueous copper-tripeptide preparation under laboratory diffusion-cell conditions. It used a different concentration, vehicle, exposure period, and experimental model from the VitaPep formula, so it does not prove how much intact GHK-Cu this serum delivers during normal use. Read the in-vitro penetration study on PubMed.
VitaPep provides this context so customers can distinguish ingredient research from finished-product performance. No controlled clinical study of this finished VitaPep formula was identified. VitaPep does not represent the serum as a treatment, cure, or prevention for any disease or medical condition.
Testing documents should be read according to the sample, batch, method, units, and scope stated by the laboratory. One report does not automatically establish every characteristic of a raw ingredient or finished formula.
| Laboratory document | Identified sample | Reported scope and result |
|---|---|---|
| Janoshik report 93405 | GHK-CU, batch GHKCU010 | Reported GHK-Cu concentration of 0.48 mg/mL for the submitted sample |
| Dyad Labs certificate 1425292-1 | VitaPep GHK-CU Serum, lot GHKCU010 | Microbiological-quality panel and arsenic, cadmium, lead, and mercury results |
These documents support the specific results they report. They do not by themselves prove a cosmetic benefit, clinical efficacy, or characteristics such as identity or purity unless a document expressly reports that characteristic.

It is a 30 mL topical cosmetic serum containing 14 mg of GHK-Cu, also known as Copper Tripeptide-1, in a listed DMSO and deionized-water carrier blend.
GHK-Cu is common shorthand for the copper complex of glycine-histidine-lysine. Copper Tripeptide-1 is the cosmetic ingredient name commonly associated with this complex. Always confirm the ingredient name on the current product label.
Each 30 mL bottle is labeled to contain 14 mg of GHK-Cu. That corresponds to a nominal calculated concentration of approximately 0.467 mg/mL.
Apply it only to clean, completely dry external skin using the applicator and amount stated on the current packaging.
No. It is formulated and sold for topical external cosmetic use only. Do not inject or ingest it.
VitaPep publishes a Janoshik concentration report and a Dyad Labs microbial and heavy-metal certificate associated with batch GHKCU010. Each document should be interpreted only according to the sample and scope identified by the laboratory.
Laboratory studies involving isolated cells help explain research interest in GHK-Cu, but they do not prove a structural or visible benefit from this finished serum in people. Human topical evidence is limited, mixed, and specific to the formulas and conditions studied.
No. Apply only to clean, intact external skin and stop use if irritation or redness occurs.
When comparing copper peptide products, look beyond broad benefit language. Compare the actual peptide amount, bottle volume, carrier ingredients, applicator, intended use, directions, warnings, and testing documentation.
