How to Verify a 1.4% GHK-Cu Hair Serum and Its COA
What CopperTheory verifiesA raw-material COA, finished-product COA, formula confirmation and independent concentration test answer different questions. Read the product-specific results page, the matching concern hub, the testing and verification guide and the complete routine for the connected evidence and routine context.
What must be verified
Verify a 1.4% GHK-Cu claim by checking the exact finished-product formula, the ingredient identity Copper Tripeptide-1, the difference between formula input and pure active, the document type and whether the record belongs to the same product or batch.
A raw-material COA, finished-product COA, formula confirmation and independent concentration test answer different questions.
The formula statement
Formula summary: 1.4% GHK-Cu and a 3.4% declared peptide complex. The 3.4% declared peptide complex is 1.4% GHK-Cu plus 2% Acetyl Tetrapeptide-3. The separate 2% Red Clover Extract is botanical support, not a peptide.
| Declared level | Ingredient or system | Role in this formula |
|---|---|---|
| 1.4% | GHK-Cu (Copper Tripeptide-1) | Core copper-peptide component of the leave-in scalp system. |
| 2% | Acetyl Tetrapeptide-3 | The second peptide in the declared peptide complex; positioned around density and follicle anchoring. |
| 2% | Red Clover Extract | Botanical support for the thinning-zone system; it is not a peptide and is not included in the 3.4% peptide total. |
| 2% | Niacinamide | Supports scalp-barrier condition, moisture balance and comfortable daily use. |
| 1% | Panthenol | Supports hydration and hair-fibre flexibility. |
| 0.10% | Sodium Hyaluronate | Lightweight water-binding support for the scalp. |
| 0.25% | Arginine | Conditioning and formula-pH support. |
| 0.20% | Allantoin | Supports comfort for dry or stressed scalp conditions. |
The declared level should be tied to the exact ingredient identity and explained consistently across product pages, evidence pages, Shopify data and articles.
Documents answer different questions
| Record | What it can support | What it does not automatically prove |
|---|---|---|
| Raw-material COA | Properties of an ingredient or supplied material. | The finished product formula or performance. |
| Finished-product COA | Specified quality attributes of the completed batch. | Every ingredient percentage or user result. |
| Signed formula confirmation | Intended composition and formula inputs. | Batch performance or long-term stability by itself. |
| Independent identity/concentration test | The measured analyte under the stated method. | Unmeasured ingredients or unrelated outcomes. |
| Performance report | A defined endpoint, method and timeframe. | Guaranteed results or different products. |
How to check a concentration claim
- Name the exact product and ingredient.
- Clarify pure active, supplied solution, complex or formula input.
- Check the method and sample identity.
- Match the record to the product or batch.
- Confirm that website wording does not go beyond the document.
Red flags in brand comparisons
- A COA badge with no explanation of whether it is raw material or finished product.
- A total peptide-complex number described as pure GHK-Cu.
- A study on a different peptide or formula presented as direct product proof.
- Hardcoded expert or laboratory claims without supporting records.
- Conflicting percentages across the product page, articles and catalog data.
