NAD+ identity and formats

Keep the material name, chemical form and package amount attached to the comparison.

Read the full identity

NAD+ names nicotinamide adenine dinucleotide in its oxidized form. Do not silently replace it with NADH, a precursor or another NAD-related product. The precise form and supplied specification should be confirmed from the label and original analytical documentation.

A coenzyme rather than a peptide

NAD+ belongs in PEL’s broader research-material catalog, but it should not be described as a peptide merely because a supplier also sells peptides.

Format matters

A lyophilized material, a solution and a differently formulated product are different offers. A shared headline amount does not resolve those differences. This guide provides no preparation, dosing or administration instructions.
