Aminos
Amino Acid & Cofactor Research Vials — United States
Two compounds on a peptide site that are not signaling peptides, shelved apart so the catalog does not imply otherwise. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme — two nucleotides joined through their phosphate groups — studied in cellular-energetics and ageing models as the substrate the sirtuins and PARP enzymes consume. Glutathione is the tripeptide γ-Glu-Cys-Gly, examined as the cell's main small-molecule antioxidant; it is a peptide by construction and a cofactor by function, and function is what this shelf is sorted by.
The vials are large — 500 mg and 1000 mg of NAD+, 1500 mg of glutathione — which makes measured content the figure to read first. A gram-scale label that is 10% short is a different product, and the certificate for each lot reports the milligrams found alongside purity, against the batch code on the vial.
Both are light- and moisture-sensitive once in solution; the storage condition on each page is specific to the compound. Supplied strictly for laboratory research, shipped domestically within the United States.

What to check before buying aminos compounds
Purity is half the number. A purity figure tells you what fraction of the powder in the vial is the compound on the label — it tells you nothing about how much powder is in the vial. A lot can assay at 99.8% purity and still be short against its labelled content.
Both numbers are published for every batch here: purity from HPLC, and measured mass against expected content. Match the batch code printed on the vial to the certificate before you rely on either.
