Testing & certificates
How to find a certificate, read its results and match it to the product and vial size you are considering.
Choose your product and vial sizeThe specification and certificate link update with the selected size.
Check the identifiersRead the material name, label claim and batch or lot number on the report. Ask us if you need help matching a report to a product or order.
Read the results in contextCompare each result with the test and acceptance criteria shown. Analysis dates describe when testing took place, not when a lot was released.
The supplied reports include identity checks, chromatographic purity and measured content per vial. Read the selected report for its methods, limits and additional results.
The reports identify the components and give a measured amount for each. Combined or peptide-related purity is not the proportion of each component in the blend.
GHK-Cu, GLOW and KLOW reports include a copper-to-GHK molar ratio. Chromatographic purity alone does not establish copper content.
NAD+ is a coenzyme. Its report includes a beta-NAD+ chromatographic assay and measured content per vial, with additional results such as NADH and ADP-ribose.
Its reports cover formulation and water quality, including benzyl alcohol concentration, pH, sterility, endotoxins and fill volume. These are not peptide-purity measurements.
The certificates currently available on product pages name Meridian Assay as the testing laboratory. Each PDF contains the reported methods, results and review details. The product specification summarises selected results; the PDF provides the full report.
A certificate reports results for the named material and batch. It does not establish suitability for human or veterinary use, or provide storage, preparation or shelf-life instructions. For a worked example, read how to read a peptide certificate of analysis.
