What is NAD+, and what is it used for?
NAD+ (nicotinamide adenine dinucleotide) is a helper molecule found in every living cell. It is sold here as laboratory material, and it is not a peptide.
NAD+ is also listed and searched as nicotinamide adenine dinucleotide, NAD plus, NAD peptide. They all mean the same compound. Supplier lists write it as NAD+ peptides or peptide NAD+ as well; every one of those is this record. A name is not a test, which is why the lot record further down counts for more than the wording on a label.
Chemically: molecular formula C21H27N7O14P2, average mass 663.4 g/mol (PubChem CID 5892). Those figures are what the identity test on a certificate is read against.
Nicotinamide adenine dinucleotide, a helper molecule rather than a peptide.
It carries hydrogen back and forth in the reactions that make energy, switching between two forms, and it is also used up as raw material by two families of enzymes, the sirtuins and the PARPs. Its basic biochemistry is textbook material and nobody disputes it.
A very large basic-science record on how cells make energy, on oxidation and reduction, and on enzymes. Most of it is about what the molecule does inside cells rather than about any product sold in a vial.
Well-understood biochemistry says nothing about any particular preparation in a vial. NAD+ is chemically different from the precursors it is often lumped in with, and material of this kind pulls in water from the air and degrades in light, which makes the handling paperwork matter more than usual.
NAD+ for sale: 100mg, 500mg and 1000mg vials, price per mg
NAD+ is sold in 3 sizes here, 100mg, 500mg and 1000mg, from $40.00 a vial. NAD+ cost and NAD+ price per mg by size are in the table, at each volume tier and on subscription; the per-mg figure under each price is the one that compares across sizes.

Subscribe & Save takes 6% every month, 4% every 2 months or 2% every 3 months off from shipment 2, two shipments minimum, and stacks on the volume tier: the lowest this record ever bills is $0.09 per mg, twenty 1000mg vials on a monthly subscription from shipment 2 onward.
Nothing is added at checkout except the USPS shipping you choose; dispatch and delivery are the same on every order. The cost-per-milligram tool ranks the whole catalog by price per mg. The certificate walked through field by field: Where to Buy NAD Plus (NAD+): Five Checks Before Ordering.
Where to buy NAD+: what to check before you order from anyone
Where to get NAD+
NAD+ for sale, or NAD+ peptide for sale, means this page: one record, 3 sizes. You can buy NAD+ online here with guest checkout; verified in-stock orders placed before 12 PM Pacific are dispatched the same day. If the question is where to get NAD+ or how to get NAD+, the answer for a US laboratory is a supplier who publishes the certificate before you pay, which is the first of the five checks that follow.
Before ordering NAD+ from anyone, us included, run the 5 checks on verifying a certificate; the first is that the report resolves on the laboratory's own site, and a seller who cannot pass them is asking for the trust a certificate exists to replace.
NAD+ reviews
No customer review of NAD+ has been published yet, so there is no star rating here; when real ones exist the number will be the arithmetic of what people wrote. Ordered this record? Leave a review. A person reads every one before it appears.
NAD+ liquid, patches or capsules? What this vial is, and is not
Search results for NAD+ also show liquid, patches, capsules products, under listing titles such as liposomal nad+, nad patches, nad pills, nad tablets, nad liposomal, nad patches reviews. Those are finished consumer goods made and marketed by other companies, and none of them is what this page sells. This record is freeze-dried NAD+ in a sealed glass vial, 100mg, 500mg and 1000mg, with a lot certificate, supplied for laboratory work. Its certificate describes that powder, not a capsule, spray or cream, which carry other ingredients and sit under different rules.
NAD+ vs Glutathione: different molecules, separate records
NAD+ vs Glutathione, or Glutathione vs NAD+, is the comparison people search most, and they are not the same thing. Each is a different molecule with a different formula, mass and research record, and each has its own certificate here.

The NAD+ certificate: lot, purity, identity, and how to verify it
A certificate answers identity, purity and net content as three separate questions, each with the method that produced it and the date it was run, how to read one covers what each field does and does not cover. For NAD+ that means a mass spectrum landing on 663.4 g/mol for C21H27N7O14P2, the figure published against PubChem CID 5892. The cataloged form is NAD+ (nicotinamide adenine dinucleotide), and the identity test resolves to that rather than to a related molecule with a similar name.
| Size | Lot | Identity method | Purity | Endotoxin · sterility · fentanyl | Test date |
|---|---|---|---|---|---|
| 500mg | LF-19B-2609 | LC-MS | 99.619% (RP-HPLC, C18, DAD @ 260 nm) | 2026-09-29 | |
| 1000mg | LF-19C-2609 | LC-MS | 99.766% (RP-HPLC, C18, DAD @ 260 nm) | 2026-09-29 |
Testing by Kovera Labs. Every batch tested on or after October 1, 2026 includes endotoxin, sterility and fentanyl screening, in addition to identity, purity and net content. Open the report, then confirm it on the issuing laboratory's own site. If the identifier does not resolve there, or resolves to a different lot than the one printed on your vial, the document is worthless however convincing it looks.

The lot number on the certificate must match the lot printed on the vial you received. That match is the only thing tying the document to your material. Net content is reported separately from purity, because a vial can be highly pure and still hold less material than its label states.

Is NAD+ a prescription drug? FDA status, and what this listing is
FDA status, and what this listing is Not an FDA-approved drug product
The FDA has not approved this compound for anything, and nothing in this catalog is a medicine.
Status verified 2026-08-25. Check the primary source before relying on this summary.
It is sold as laboratory material under the research-use restriction below. Being listed is not an approval, and not a claim that it is safe, effective or right for any purpose. LabFirst is not a pharmacy or a compounding facility, this vial is not a compounded medicine, and no prescription is involved, because it is not sold for use in anyone. Search results also show compound NAD+ and NAD+ compound offers from compounding pharmacies; a compounded NAD+ is a prescription product prepared for a named patient, and a certificate for this lot says nothing about one.
NAD+ research: what the published studies examine
Status: No FDA-approved application. This compound is sold as laboratory material. Where research on it has been published, it sits at the animal, cell or early-human stage, and this record does not summarize what it found. A supplier is not a neutral judge of evidence about its own catalog.
NAD is not a peptide and not a signal in the usual sense. It is a helper molecule, the cell’s hydrogen carrier for energy reactions, and separately a raw material that three families of enzymes chop up: the sirtuins, the PARPs and CD38. That second job is what drives current interest, because those enzymes destroy NAD rather than just borrowing it, so their activity drains the pool. The amount in a cell is not fixed.
It rises and falls with eating, exercise and time of day, and it drops with age, which is the observation the whole field is built on. The important catch, and the one most often skipped, is getting it in. NAD is a big charged molecule and does not cross a cell membrane freely, so NAD outside a cell is largely broken down into smaller pieces before anything reaches the pool inside.
That is why most of the serious work in this area uses those smaller pieces, nicotinamide riboside and nicotinamide mononucleotide, rather than NAD itself.
| Reported observation | Model | Source |
|---|---|---|
| A review of the animal evidence describing NAD’s two jobs, as hydrogen carrier and as raw material for enzymes that sense the cell’s state, including sirtuins, PARP1 and CD38. It records how the amount changes with food, exercise and the daily clock, and how it falls steadily with age. Putting NAD back in old or sick animals is reported to improve health and extend life in those models, which is the basis for the hunt for NAD-raising molecules. | review of animal in vivo evidence | Rajman, Chwalek and Sinclair, Therapeutic potential of NAD-boosting molecules: the in vivo evidence, Cell Metabolism (2018)Authored by a leading proponent of the field, which is worth knowing when reading the strength of its framing. The animal findings it reviews are real; the enthusiasm is not neutral. |
| While testing inhibitors of an enzyme called NNMT, researchers raised NAD inside fat cells indirectly, by blocking the enzyme that consumes NAD’s precursor, rather than by adding NAD from outside. The approach says something about the pathway: the pool inside a cell gets moved by the enzymes that build and consume it, not by putting the molecule in the dish. | cultured adipocytes with intracellular metabolite measurement | Neelakantan and colleagues, Selective and membrane-permeable small molecule inhibitors of nicotinamide N-methyltransferase reverse high fat diet-induced obesity in mice, Biochemical Pharmacology (2017) |
Open questions. The biochemistry of NAD is textbook material and the age-related decline is well documented. The open question is whether supplying NAD from outside a cell changes anything inside it. NAD does not cross the membrane freely; outside the cell, enzymes break it into precursors, which are then taken up and rebuilt. That makes giving NAD an indirect and inefficient way of delivering precursors at best, and it is the reason the research field works with nicotinamide riboside and nicotinamide mononucleotide instead.
Beyond that: most of the lifespan findings are in mice and other short-lived animals; human trials of NAD precursors have generally shown that the markers in blood can be raised while the clinical results have been far less consistent; and CD38 activity climbs with age, meaning the pool is being drained faster at exactly the point supplementing is proposed. Anyone comparing products in this category should ask what is actually in the vial and by what route it is supposed to reach a cell.
Each row above describes an observation in the stated model. None of it describes what NAD+ would do in a person or an animal outside that model, and none of it is a recommendation to use it for anything.
How to store NAD+: refrigeration and shelf life
Keep the sealed vial cold and out of the light and it stays as it left the lab. Once it is mixed into a solution, how long it holds up depends on the compound, what it was mixed with, how strong the solution is and how cold it is kept — too many variables for anyone to print one shelf life on a label. So laboratories write the date on whatever they prepare and keep their own record of it.
For solution preparation arithmetic on the bench, concentration, per-graduation values and molarity, use the vial concentration calculator, which opens with the NAD+ sizes stocked here already loaded. It covers laboratory measurement only and contains no administration guidance.
