The per-mg and multi-vial math is broken down on the NAD+ price per vial page, and the longevity research overview sets NAD+ beside the other compounds studied in that area. The reconstitution calculator does the arithmetic for mixing the vial with bacteriostatic water and reports it in units rather than mL.

Before you buy
What should you check before you buy NAD+?
Check that the certificate is for a vial of NAD+ itself, not for an oral precursor, and that it states both identity and the amount actually measured in the vial. The released batch, lot NAD-20260619-04, shows identity by HPLC-RTM + LC-MS with a measured mass of 664.12 m/z [M+H]+, 95.84% purity by HPLC against a not-less-than 95.0% release criterion, and 1012.17 mg of net content against the 1000mg on the label.
- Vial, not capsule. NMN and NR are oral precursors sold as supplements. A research vial of NAD+ is a different product, so compare vial with vial.
- Identity, not only purity. A purity figure says a sample is mostly one compound; the LC-MS identity result is what says that compound is NAD+.
- The rest of the panel. Titreon Analytical's certificate also reports sterility, bacterial endotoxin, heavy metals and a fentanyl screen for the batch.
- Your own batch. Vials ship unlabeled on purpose, so verification runs on your order number. Message us on WhatsApp with it and we will confirm your batch and send its published certificate.
The checks that apply to any seller are in how to verify peptide purity, and the full certificate for this batch is on the NAD+ certificate card.
The short answer
What is NAD+?
NAD+ is nicotinamide adenine dinucleotide, a coenzyme present in every cell and one of the oldest molecules in biochemistry. It has two jobs in the published account. The first is redox: it shuttles electrons between the reactions that release energy from fuel, cycling between an oxidized and a reduced form without being used up. The second is as a consumed substrate, because sirtuins and PARP enzymes cleave NAD+ as part of their normal signaling, which ties the coenzyme's supply to those pathways (Covarrubias et al., 2021). Reviews of NAD+ metabolism describe tissue levels falling with age, which is the observation that turned a textbook cofactor into a research target (Covarrubias et al., 2021; Rajman et al., 2018). Peptara supplies research-grade NAD+ as a lyophilized 1000mg vial for laboratory research; this page describes what published reviews report, not an effect in any person, and a qualified clinician is the only place a personal question belongs.
The Science
A Cofactor That Is Also a Currency
Most cofactors are recycled. NAD+ is recycled for its redox work and spent for its signaling work, and that second role is what makes its supply a variable rather than a constant. The published literature is built around that distinction.
Redox Carrier
Cycles between oxidized and reduced forms, carrying electrons through energy metabolism.
Signaling Substrate
Cleaved rather than returned by sirtuins and PARP enzymes, so those pathways draw on the pool.
Falls With Age
Reviews describe tissue levels declining over time across model systems.
Applications
Common Research Areas
Energy Metabolism
The redox role in the reactions that release energy from fuel is the best established part of the record.
Sirtuin Biology
Sirtuins consume NAD+, so the coenzyme appears throughout that literature as a dependency.
DNA Damage Response
PARP enzymes also cleave NAD+, which is why DNA repair work touches the same pool.
Age-Related Decline
The reported fall in tissue levels with age is the research area, not a demonstrated intervention.
Naming
NAD+, NMN and NR: what the names mean
These three are routinely treated as interchangeable and they are not. NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are intermediates in the salvage pathway that builds NAD+. They are precursors. NAD+ is the coenzyme itself, the molecule the redox and signaling reactions actually use. Yoshino and colleagues set the two apart explicitly, reviewing the biology of the intermediates as their own subject with their own evidence base (Yoshino et al., 2018).
The distinction matters when reading a study. A trial of NR is a trial of a precursor and its absorption, conversion and downstream effect; it is not a direct measurement of NAD+ itself. What ships here is NAD+ as a lyophilized 1000mg vial, so papers about NMN or NR describe a related molecule rather than this one, and this page does not borrow their results.
Evidence
How strong is the NAD+ evidence?
The mechanistic account is well established. NAD+ metabolism, the enzymes that consume it, and the reported decline in tissue levels with age are all covered in detail in the review literature (Covarrubias et al., 2021). That is the settled part.
The unsettled part is whether raising NAD+ changes an outcome. Rajman and colleagues reviewed the in vivo evidence for NAD-boosting molecules and were explicit about the shape of it: substantial animal work, and a human record that is smaller and earlier than the attention the field receives (Rajman et al., 2018). This page reports that gap rather than writing over it. No result here is an outcome claim, and nothing on this page is medical advice.
The released NAD+ batch is lot NAD-20260619-04, certificate COA-2026-9502, tested at 95.84 percent purity by HPLC, and its certificate is published in full on the certificates page.

The coenzyme
NAD+ is nicotinamide adenine dinucleotide, a redox coenzyme that carries electrons through the reactions of energy metabolism in every cell (Covarrubias et al., 2021).
The second job
It is also consumed as a substrate rather than only recycled: sirtuins and PARP enzymes cleave NAD+ as part of their normal signaling, which links its supply to those pathways (Covarrubias et al., 2021).
The decline
Published reviews describe tissue NAD+ falling with age across model systems, which is why the coenzyme became a longevity research target at all (Covarrubias et al., 2021; Rajman et al., 2018).
The open question
Rajman and colleagues reviewed the in vivo evidence for NAD-boosting molecules and set out what animal work has shown against what human work has not yet settled (Rajman et al., 2018).

Buying NAD+: FAQ
Where can I buy NAD+?
Peptara Labs sells NAD+ online as a 1000mg research-grade vial of lyophilized powder, ordered from this page. It is sold as research-grade material for laboratory research use, so the batch certificate is the thing to compare between sources.
How much does NAD+ cost?
One 1000mg vial is $150 USD, which is $0.15 per mg. Signing up by email takes 15 percent off a first order, which brings a vial to $127. Buying more of the same compound lowers the per-vial price on that line, to 40 percent off at 10 vials, which is $90 each.
Does Peptara Labs ship NAD+ to the US?
Yes. Orders to the United States, Canada, the United Kingdom and New Zealand ship tracked in 5 to 10 business days, guaranteed. Shipping is a flat $35, free over $250.
How do I verify the purity of NAD+ before I buy?
Read certificate COA-2026-9502 for the released batch, lot NAD-20260619-04: 95.84 percent purity by HPLC, identity by HPLC-RTM + LC-MS with a measured mass of 664.12 m/z [M+H]+, and 1012.17 mg of net content in a 1000mg vial, tested by Titreon Analytical, whose panel also reports sterility, bacterial endotoxin, heavy metals and a fentanyl screen. Vials ship unlabeled, so your order number on WhatsApp is what ties your vial to its batch certificate.
Is a NAD+ vial the same as an oral NAD+ supplement?
No. Oral precursor supplements, such as NMN or NR capsules, and research-grade lyophilized NAD+ in a vial are different products sold on different terms, so a price comparison between them is not like for like. This page is about the research vial only.
What comes with a NAD+ order?
One sealed 1000mg vial of lyophilized NAD+ and bacteriostatic water to reconstitute it, plus a printed reference guide to what published studies reported. The batch certificate is published on the certificates page, because the vial itself ships unlabeled.
Is NAD+ for human use?
No. The NAD+ vial is sold as research-grade material for laboratory research use only, not for human use. There is no approved NAD+ product for the uses discussed in the research literature.
NAD+ FAQ
What is NAD+ and what does it do in a cell?
NAD+ is nicotinamide adenine dinucleotide, a coenzyme found in every cell. Its first role is redox: it carries electrons between the reactions that release energy from fuel, cycling between an oxidized and a reduced form. Its second role is as a consumed substrate, because sirtuins and PARP enzymes cleave NAD+ as part of their normal signaling rather than handing it back. Published reviews describe both roles and the way the coenzyme connects metabolism to those signaling pathways (Covarrubias et al., 2021).
Why is NAD+ studied in the context of aging?
Because the published record describes tissue levels falling over time. Reviews of NAD+ metabolism report a decline with age across model systems and set out how that decline is thought to intersect with the cellular processes NAD+ participates in (Covarrubias et al., 2021). That observation is what made the coenzyme a research target; it is a description of what studies report, not a claim about any person.
What is the difference between NAD+, NMN and NR?
NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are intermediates in the pathway that builds NAD+. They are precursors, not the coenzyme itself, and the literature treats them as a separate question with its own biology and its own trial record (Yoshino et al., 2018). What ships here is NAD+ as a lyophilized 1000mg vial, so papers about NMN or NR are about a related molecule rather than about this one.
Is NAD+ an approved medicine?
No. Peptara Labs supplies research-grade NAD+ for laboratory research. There is no approved NAD+ product for the uses discussed in this literature, and nothing on this page is a medical claim or a recommendation. Anything relating to a diagnosed condition is a conversation for a licensed clinician.
How strong is the human evidence?
It is early. The clearest published work is mechanistic and preclinical, and the reviews that summarize the in vivo evidence for raising NAD+ are explicit about the gap between what animal studies have shown and what human studies have settled (Rajman et al., 2018). This page reports what those reviews say, including the limits they state.
Is Peptara Labs a real company?
Yes. Peptara Labs is a registered business with responsive customer support via WhatsApp. Unlike anonymous Telegram sellers, we stand behind every order with our name, reputation, and ongoing support.
Are your peptides real?
Every NAD+ vial comes with a third-party Certificate of Analysis (COA) confirming identity and purity. We source from verified manufacturers and can provide lab documentation upon request. If you want to see a COA before ordering, message us on WhatsApp and we'll send it over.
Will the vial survive shipping and heat?
It ships in lyophilized (freeze-dried powder) form, which is stable at room temperature for weeks, and fast tracked delivery keeps transit short. Handling and storage instructions are included with every order.
I can find cheaper compounds on Telegram.
You can. But you don't know what's in them, who made them, or how they were stored. Telegram sellers operate anonymously with no accountability. No COA. No real company behind them. No support if something goes wrong. Our price includes third-party testing, fast delivery, bacteriostatic water, COA access, and educational support. We don't just sell peptides. We make sure you get a verified, properly handled product you can trust.
Is my payment secure and discreet?
Yes. We accept Visa, Mastercard and Amex cards, bank transfer, and USDT, USDC or BTC crypto, and we handle every order discreetly. All transactions are secure and your financial information is never stored. If you have concerns about a specific payment method or about discretion, message us and we'll find an option that works for you.
