Certificates are available on product pages. Select the vial size, then open the certificate preview or download the PDF. Check the material name, label claim and lot number in the report.

Chromatographic purity and the amount of material per vial are separate measurements. A purity percentage does not tell you how many milligrams are in the vial. Product specifications show the reported results separately from the labelled vial size.

No. Blend reports include amounts for individual components, copper-complex reports include a copper-to-GHK ratio, and NAD+ has a coenzyme-specific assay. Bacteriostatic water has formulation and water-quality tests rather than peptide purity.

Contact us before ordering for storage conditions and handling documentation for the selected batch. The supplied certificates report analytical results; they do not provide storage or preparation instructions.

No reconstitution guide is supplied. Contact us before ordering if your research requires preparation information for a particular material; do not assume the same diluent or volume applies to every product.
