We test every lot.
The full standard →Every production lot clears six independent checks before release, and its certificate resolves from the vial's QR code to a permanent public record for that exact lot. Scan it, read it, trust it. That is the whole model.

Questions researchers ask.
Is GHK-Cu legal to buy for research?
GHK-Cu and the other compounds sold here are research materials, offered for in-vitro and laboratory research use only. They are not sold for human or veterinary use and are not drugs, foods, cosmetics, or supplements.
Why does net peptide content matter, not just purity?
Purity is the share of the peptide present that is the target peptide. Net peptide content is how much of the vial’s mass is actually peptide, versus water and salts. We report both, because only together do they describe what is in the vial.
What is a certificate of analysis (COA)?
A COA is the analytical laboratory’s report on a specific lot: identity, purity, and contaminant results. NOVA Q publishes a lot-specific COA that resolves from the vial’s QR code to a permanent record for that exact batch.
