NAD+ pens UK: the 1000mg format explained

The short answer

Vivora's NAD+ 1000mg pen pack is sold as a 1000mg box: two pre-filled pens of 500mg each, in one sealed, batch-coded window box, at £160 per box. The 1000mg figure is the box total, not the content of a single pen. The catalogue code is VV-ND.

NAD+ is nicotinamide adenine dinucleotide. Chemically it is a dinucleotide coenzyme, not a peptide: it contains no amino acids at all. Vivora lists it next to its peptide research pens because it is supplied in the same pre-filled format, not because it belongs to the same class of compound.

Like everything in the range, the pens are laboratory research materials. They are not a medicine or a food supplement, they are not for human or animal use, and they are supplied without preparation, dosing or administration guidance.

Is NAD+ a peptide?

No. The MeSH (Medical Subject Headings) vocabulary defines peptides as compounds made of amino acids joined together by peptide bonds between adjacent amino acids, in linear, branched or cyclical structures. Even the shortest peptides fit that description: MeSH classes chains of roughly 2 to 12 amino acids as oligopeptides, and longer chains as polypeptides.

NAD+ is built differently. MeSH describes NAD as a coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by a pyrophosphate linkage. In plainer terms, it is two nucleotides joined through their phosphate groups: one carries nicotinamide and the other carries adenine. PubChem's record says the same thing directly, describing the compound as a dinucleotide of adenine and nicotinamide.

There is no amino acid and no peptide bond anywhere in that structure, so NAD+ is not a peptide, however it is packaged. Size is not the test. GHK, one of the components named on Vivora's GLOW 70mg pen, is far smaller than NAD+ but is still a peptide, because it is a chain of three amino acids: glycine, histidine and lysine.

The distinction matters in practice. Laboratory stock lists, purchasing categories and supplier comparisons are usually grouped by compound class. Filing NAD+ under peptides because it arrives in the same kind of pen misdescribes it, and the error tends to travel into every later record that copies the category.

NAD+ in chemical terms

PubChem lists oxidised NAD+ under the name Nadide (CID 5892), with the molecular formula C₂₁H₂₇N₇O₁₄P₂, a molar mass of 663.4 g/mol and CAS number 53-84-9. Vivora's product page gives the same CAS number, formula and molar mass in its compound reference, and states the form as oxidised (NAD+).

The plus sign matters. MeSH notes that the molecule serves as an electron carrier in enzymatic reactions, alternating between an oxidised form, NAD+, and a reduced form, NADH. The reduced form has its own PubChem record, NADH (CID 439153), with the formula C₂₁H₂₉N₇O₁₄P₂ and a molar mass of 665.4 g/mol: two hydrogen atoms more than NAD+. For record-keeping, NAD+ and NADH are different substances, even though the names are close.

Record the compound as NAD+, give the full name, nicotinamide adenine dinucleotide, alongside it, and note the oxidised form. If a document you receive names NADH, or names "NAD" without saying which form, query it rather than assuming the two are interchangeable. Recording the CAS number as well as the name removes most of the ambiguity, because the name appears in several spellings across catalogues and databases.

What the 1000mg box contains

• Product: NAD+, catalogue code VV-ND.
• Description: nicotinamide adenine dinucleotide, 2 × 500mg.
• Label strength: 1000mg per box.
• Pens per box: two pre-filled research pens, each stated as 500mg.
• Packaging: one sealed, batch-coded window box holding both pens.
• Price: £160 per box, with the UK delivery charge shown before payment.

The listing states both the box total and the amount in each pen, which makes NAD+ the simplest two-pen product in the range to record. GLOW, the other two-pen line, states its component amounts but not how they divide between its pens; NAD+ has a single component and a stated per-pen figure.

Label strength is the supplier's stated content. It is not a measurement. Keep the two ideas apart in your records: the stated amount belongs in one field, and any independently measured figure, taken from a report you have checked yourself, belongs in another. Never overwrite one with the other.

Box total versus per pen

The most common recording error with two-pen boxes is mixing up the box figure and the pen figure. For NAD+, write both down: 1000mg for the box and 500mg for each pen. When either figure is used later, in a stock list, a sample record or a price comparison, label which one it is.

If the two pens go to different storage locations or experiments, log each one against the same batch code so that both stay linked to the same box. When a pen is used up or discarded, record the date against that code. Our label-reading guide goes through each printed field in order.

Fill volume and concentration are separate figures again, and the label strength does not give you either. If your records need them, ask Vivora before ordering rather than estimating them from the stated milligrams.

Price per mg for NAD+ pens

At £160 for 1000mg, Vivora's NAD+ box works out at £0.16 per mg, or £80 for each 500mg pen. UK delivery is currently £4.95 per order and is shown before payment. A single box with delivery comes to £164.95, which is about £0.165 per mg; adding further boxes to the same order spreads the delivery charge across more milligrams. From 5 boxes, mixed across the range, wholesale pricing applies instead.

To compare NAD+ listings fairly:

• Compare NAD+ with NAD+ only. A 1000mg NAD+ box and a 40mg single-pen peptide listing describe different substances, so their prices per mg say nothing useful about each other.
• Work from the box total and the number of containers, not from a single container figure.
• Note the format. A pre-filled pen includes the device and the filling step, so pens usually cost more per mg than vials with the same stated amount.
• Check whether a figure is a label claim or a measured result. If a seller publishes a test report, check that it verifies on the testing laboratory's own website rather than relying on an image.
• Add the delivery charge before dividing, and use the same basis for every listing you compare.

Research use only

Vivora supplies NAD+ as a laboratory research material. Its research-use policy states that its products are not a medicine, food supplement, cosmetic or medical device, and they are not for human or animal use. The listing comes without preparation, dosing or administration guidance, and Vivora does not provide that guidance on request.

Buyers must be 18 or over and must confirm research use before an order is accepted. Orders that indicate human or animal use are cancelled and refunded. Read the research-use policy before ordering, then see the current range for pack contents and prices.

Common questions

Is NAD+ a peptide?

No. NAD+ is a dinucleotide coenzyme built from two nucleotides. A peptide is a chain of amino acids, and NAD+ contains none.

How much NAD+ is in each Vivora pen?

The listing states 500mg per pen, with two pens per box for a 1000mg box total.

What is the price per mg?

£160 for 1000mg is £0.16 per mg before delivery. UK delivery is currently £4.95 per order.

Is NAD+ the same as NADH?

No. NAD+ is the oxidised form and NADH is the reduced form. They have different formulas and separate PubChem records.

Is Vivora's NAD+ sold as a supplement?

No. It is supplied as a laboratory research material. It is not a food supplement or a medicine and is not for human or animal use.
