Cellular Stack

What is the Cellular Stack?

The Cellular Stack is a research convenience bundle of three separate reference materials supplied as individual lyophilised (freeze-dried) vials: NAD+ (500mg), Epithalon (10mg) and Glutathione (1500mg). It is not a single combined product or formulation. Each compound is a distinct vial with its own batch and its own Certificate of Analysis. Within the research community this grouping is sometimes searched for as the "nad stack" or "cellular peptide stack"; that is a search term and an informal label only, not a description of any effect. All items are supplied strictly as research reference materials and are not for human or veterinary use. See our research disclaimer.

What is in the Cellular Stack?

The bundle contains three separately packaged compounds, each linking to its own product page where the chemistry and identifiers are listed:

NAD+ (500mg) - Nicotinamide adenine dinucleotide, a dinucleotide coenzyme, supplied as a lyophilised powder.

Epithalon (10mg) - the tetrapeptide Ala-Glu-Asp-Gly, supplied as a lyophilised powder.

Glutathione (1500mg) - the tripeptide gamma-glutamyl-cysteinyl-glycine (GSH, reduced), supplied as a lyophilised powder. All three also appear in our cellular research category.

Is the Cellular Stack legal in the UK?

None of the three compounds in this bundle is a controlled drug under the Misuse of Drugs Act 1971. They are supplied as research reference materials for laboratory use only and are not for human or veterinary consumption. They are not medicines, are not licensed for any therapeutic indication, and are not sold to diagnose, treat, cure or prevent anything. The buyer is solely responsible for handling these materials lawfully and in line with all applicable regulations. For more on how we frame our materials, read the research disclaimer.

Why are these compounds studied together?

NAD+, Epithalon and Glutathione each appear in the published literature within the same broad research area - cellular biochemistry, including topics such as NAD redox biology and telomere biology. People who buy them together typically want one set of reference materials for a single area of study. To be clear: co-occurrence in the same research area is not evidence of any combined effect, and we make no claim that these compounds act together, synergise, or produce any combined result. There is no demonstrated combination effect in humans. For background on the research area at a compound level, see our NAD coenzyme research monograph.

How is quality assured?

Each of the three vials is an independent compound with its own batch and its own third-party Certificate of Analysis confirming minimum purity by HPLC. Every constituent is specified at >=99% (HPLC). Because each vial is sourced and released separately, the CoA for one compound does not cover the others - check the certificate for each individual batch. All published certificates are available on our Certificates of Analysis page.

Supply and reconstitution

The Cellular Stack ships as three separate lyophilised vials, not as a pre-mixed solution. Lyophilised powders are typically reconstituted in a laboratory with a suitable solvent such as bacteriostatic water before analytical work; each compound is handled separately as its own reference material. Orders are despatched from the UK. For batch documentation see the CoA page, and for the standing usage position see the research disclaimer.
