Verified batches
Third-party purity results for GHK-Cu
Blinded retail purchase, labels stripped, RP-HPLC in triplicate against a reference standard, published pass or fail.
No batches published yet — first blinded results in progress
When a GHK-Cu lot completes testing, this section carries the lot number, the claimed and measured purity, the delta between them, the method, the laboratory and the chain-of-custody note. Read the methodology.

Enter a measured purity from a result you trust. VialPost does not supply a default purity figure, because assuming one would defeat the point of measuring it.

Questions
GHK-Cu — frequently asked
- How is the GHK-Cu price per milligram calculated?
- The observed vial price is divided by the mass printed on the vendor listing. Only single-vial listings are used; multi-vial kits and multi-component blends are excluded because their per-milligram figures are not comparable to a single vial of one compound.
- Is the cheapest GHK-Cu listing the best value?
- Not necessarily. Price per milligram assumes the label is accurate. If a vial assays below its claimed purity, the real cost of a milligram of the compound is higher than the sticker figure — which is what the cost-per-verified-milligram calculator on this page shows.
- Has VialPost tested GHK-Cu?
- Not yet. The verified batch registry is empty while the first blinded retail purchases are in progress. No purity figure for this compound is published on this site until a third-party laboratory has returned a result.
