NAD+ where to buy is a search people run at the end of a bad month, when sessions have gone flat and sleep has not fixed it. That is the worst state to assess a supplier from, because the checks that matter are dull and the marketing is not.
Key takeaways
- NAD+ is a coenzyme rather than a peptide, and it sells in grams instead of the 5 to 10 mg vials the rest of this market uses. The only price figure worth comparing is per 100 mg.
- Grade is the criterion almost nobody checks. FDA has stated it is aware of compounders using food-grade NAD+ sold by repackagers to make intravenous products.
- Ask whether the batch certificate reports endotoxin testing, not identity and purity alone. FDA linked reports of severe chills, shaking, vomiting and fatigue after NAD+ injectable drugs to excessive endotoxin levels.
- NAD sits in FDA's 503A Category 1 list, which means bulk drug substances under evaluation and a stated non-enforcement position while that evaluation runs. It is not an approval.
- The listing we point readers to is NAD+ 1,000 mg at $104.00, or $52.00 with code PEPTIDEDECK, which works out at $5.20 per 100 mg with two independent batch reports published on the page.
The vendor we point lifters to
NAD+ from Ascension Peptides
Independently assayed material, dispatched from the US. The vial drops by half with the code below.
Quoted per 100 mg because NAD+ is dosed in hundreds of milligrams, not the single milligrams a peptide vial holds. Buying 3, 5 or 10 takes 3%, 5% or 10% off the list price. Free shipping starts at $250.
- Two independent lab reports per batch
- Free delivery above $250
- Same-day dispatch on orders before 2pm CST

Start by knowing what you are buying
Everything else on this site is a peptide. NAD+ is not one. Nicotinamide adenine dinucleotide is a coenzyme your cells already make and spend continuously, the electron carrier that sits inside glycolysis, the citric acid cycle and oxidative phosphorylation, and a substrate for enzymes including the sirtuins and PARPs. That biochemistry is settled and uncontroversial.
The leap that sells vials is a different claim: that levels fall with age, and that putting more in from outside restores something you have lost. The first half of that has observational support in the published literature. The second half, specifically the part where an infusion or an injection improves how you train, has not been settled by a finished human efficacy trial, and the registered trial list is a good check on anyone who tells you otherwise.
That matters for buying because it sets the ceiling on what a good supplier can give you. A supplier can give you confidence about what is in the container. Nobody in this market can give you an adaptation.
NAD+ where to buy: the checks that survive a tired week
Eight criteria, in the order they actually filter. The first two do most of the work and are the two that get skipped.
| Criterion | What a real answer looks like | Where you check it | What it protects against |
|---|---|---|---|
| Grade | A stated pharmaceutical or equivalent specification, never "food grade" and never silence | Product page or spec sheet | The precise problem FDA named in its compounding notice |
| Endotoxin result | A bacterial endotoxins result on the batch report, alongside identity and purity | The certificate of analysis | Reactions that put people in a clinic chair with rigors |
| Two identity methods | Mass spectrometry for identity plus HPLC for purity, not one number | The certificate | Wrong compound, or a degraded one |
| Batch specificity | A lot number and test date on the certificate that matches the container | Certificate and vial label | A generic catalog certificate reused across everything |
| Named laboratory | A testing lab with a name and an address you can search | Certificate header | In-house numbers presented as third-party testing |
| Quantity and unit price | Grams or milligrams stated plainly, with a per 100 mg figure you can derive | Listing | Per-milligram comparisons that read as trivially cheap |
| Dispatch and recourse | Domestic dispatch, a stated returns position, a business address | Shipping and terms pages | Customs seizure and total loss with no counterparty |
| Research-use language | Clear laboratory-use wording and no human-use claims | Listing | A seller already ignoring the rules it sells under |
A supplier can miss one of these and still be fine. Two is a pattern, and the pattern usually points the same way.
Grade is the criterion almost nobody checks
This is where NAD+ differs from every peptide on this site, and it is worth reading FDA's own wording rather than a summary of it. In a notice with content current as of 10/30/2024, the agency reminded compounders to use ingredients suitable for sterile compounding and said it "is aware of compounders using food-grade nicotinamide adenine dinucleotide (NAD+) sold by repackagers to make intravenous products."
The reason that is a problem is stated in the same notice: "Ingredients identified as food grade are not suitable for compounding sterile drugs without appropriate processing, due to the high risk of contamination with microbes and endotoxins, which can harm patients."
Then the consequence. FDA reported it "has received adverse event reports following use of NAD+ injectable drugs, including severe chills, shaking, vomiting and fatigue with some requiring medical treatment," and added that "these reactions are consistent with excessive levels of endotoxins."
Read that as a buying instruction rather than a news item. The material that caused those reports was being sold by repackagers into clinics, which means the failure was upstream of the person holding the syringe. Asking a seller what grade the raw material is, and getting a specific answer, is the single highest-value question in this market.
What endotoxin testing is actually for
Endotoxin is not the same thing as purity, and a chromatogram will not catch it. It is bacterial debris rather than a live organism, it persists after the bacteria that produced it are gone, and it is measured by a separate compendial assay, the bacterial endotoxins test, usually described on a certificate as LAL. FDA maintains a questions and answers guidance on pyrogen and endotoxins testing that treats it as its own discipline, which is the point.
So a certificate showing 99 percent purity by HPLC and a clean mass spectrum has answered a question nobody was hurt by. It has said the container holds NAD+ and not something else. It has not said the material is free of the contaminant FDA connected to the reports above.
If a seller publishes identity and purity and nothing else, ask for the endotoxin result specifically. The answer, including a refusal or a vague one, is informative.
The regulatory position, in one paragraph
NAD is listed in FDA's 503A Category 1, which the agency titles "Bulk Drug Substances Under Evaluation," on the bulk drug substances category lists updated May 14, 2026. Category 1 means FDA does not intend to take action against a compounder for compounding with that substance while the conditions in its guidance are met. It is a stated non-enforcement position pending an evaluation that is still running, not an approval, and the list can change.
One trap worth knowing: Beta-Nicotinamide Adenine Dinucleotide Disodium Salt Trihydrate appears in Category 3, nominated without adequate support, in the same category list. It reads like the same substance under a longer name and it sits in a different bucket. The full version of this, including what it means for a prescription route, is in NAD+ without prescription.
How the listing we point to scores
Ascension lists a single NAD+ presentation, 1,000 mg, at $104.00 from a $179.99 reference price, and $52.00 once the code is applied. That is $5.20 per 100 mg. Quantity tiers of 3, 5 and 10 take 3, 5 and 10 percent off list separately, and free shipping starts at $250. The arithmetic in full sits in NAD+ price, and the code specifically in NAD+ coupon.
On documentation, the product page publishes two independent third-party reports for the batch, currently Kovera Labs batch 25-05260628 tested June 14, 2026 and MZ Biolabs batch 25-01260229 tested January 26, 2026, with same-day dispatch on orders before 2pm CST and research-use-only language on the listing. That is a documentation position we read off the page, not a laboratory verification we performed.
On the criterion that matters most, be direct: if the published reports cover identity and purity but not bacterial endotoxins, that is the question to put to the seller before ordering, and it is the question to put to every other seller as well. A vendor that answers it with a document is telling you something real. This is the same standard we applied to BPC-157 where to buy and where to buy MOTS-c, with one difference: for those compounds, endotoxin is a general sterility concern. For NAD+, it is the specific thing regulators went on record about.
What a verified gram will and will not do for training
The honest version for a lifter is short. NAD+ is central to energy metabolism, and fatigue is a metabolic-sounding complaint, so the marketing writes itself. But flat sessions across a block are usually explained by things with much better evidence behind them: sleep debt, an aggressive deficit, accumulated volume without a deload, or the lean-mass drift that comes with an incretin drug.
We have covered those elsewhere and they are worth exhausting first, in sleep and myostatin, resistance training and myostatin, and, if a GLP-1 is in the picture, myostatin inhibitors and GLP-1 muscle loss. None of those cost $52.
If you buy anyway, buy on the checklist above rather than on the promise, and keep dosing questions where they belong: PeptideDosage maintains a NAD+ dosage reference and a NAD+ calculator, and no research supplier is permitted to discuss either with you.
Frequently asked questions
What is the most important thing to check when deciding where to buy NAD+?
The grade of the raw material, then whether the batch certificate reports bacterial endotoxins. FDA's compounding notice named food-grade NAD+ sold by repackagers as a live problem and tied adverse event reports to excessive endotoxin levels, so those two questions sit above price, shipping speed and brand reputation.
Is NAD+ a peptide?
No. It is a coenzyme, nicotinamide adenine dinucleotide, which cells make and spend continuously. It is not built from amino acids at all, and it sells in gram quantities rather than the 5 to 10 mg vials that peptides come in, which is why a per-milligram price comparison against a peptide is meaningless.
Does Category 1 mean NAD+ is FDA approved?
No. Category 1 on the 503A bulk drug substances list means "under evaluation," and FDA has said it does not intend to act against compounders using those substances while the conditions in its guidance are met. That is non-enforcement during an open evaluation, not approval, and the categories are revised over time.
Why is NAD+ priced per 100 mg here rather than per milligram?
Because the quantities are two orders of magnitude apart from a peptide vial. A 1,000 mg presentation at $52.00 is $5.20 per 100 mg. Expressed per milligram it reads as five cents, which invites a comparison against peptide pricing that tells you nothing useful.
Will a well-tested vial fix flat training?
There is no finished human efficacy trial showing that exogenous NAD+ improves training capacity, so nothing about the supplier changes that. A good supplier gives you confidence in what the container holds. Sleep, calorie intake and programming remain the parts of a flat block with real evidence behind them.
This article is for educational purposes only and is not medical advice. NAD+ is a coenzyme rather than an approved injectable medicine: there is no FDA-approved NAD+ drug product, material sold by research suppliers is labeled for laboratory use only and not for human consumption, and compounded preparations exist under a stated enforcement policy rather than an approval. Speak with a qualified healthcare professional before making any decision involving injections, infusions or off-label compounds.
