Is pharmaceutical grade NAD+ the same as high purity NAD+?

No, and conflating them is the most common error in this market. Purity describes how much of the powder is the compound. Grade describes the standard the facility manufactured to, including bioburden and endotoxin control. Food-grade material can be 99% pure and still carry the endotoxin load FDA warned compounders about.

What should an NAD+ certificate of analysis actually contain?

Identity, ideally by mass spectrometry. Purity, ideally by HPLC. A quantification of how much is in the vial. A lot number matching the batch you are buying. And for anything intended for solution, a bacterial endotoxins result. Most research certificates cover the first four and stop.

Why is NAD+ priced per 100 mg here instead of per mg?

Because a gram is the unit this compound is sold in. A per-milligram figure on a 1,000 mg vial comes out at around five cents and invites a comparison with peptides priced at several dollars per milligram, which tells you nothing. Per 100 mg keeps the arithmetic legible. The full breakdown is on our [NAD+ price](/nad/nad-price/) page.

Can a pharmacy sell me NAD+?

A 503A compounding pharmacy can prepare an NAD+ product under FDA's interim category 1 policy, with a prescription, which is a real route that does not exist for most research peptides. What you get is a compounded drug, which FDA does not review for safety, effectiveness or quality before it is marketed.

Is NAD+ related to the GLP-1 medications on this site?

No. It has no incretin receptor activity, no effect on gastric emptying, and no weight-loss indication anywhere. People buy it alongside a GLP-1 because of fatigue in a deficit, not because the two act on the same system.

NAD+ Where to Buy: Grade Decides It, Not Price

Summary: The gap between a real NAD+ supplier and a repackager is not price, it is grade and testing scope. This page turns FDA's own food-grade warning into a checklist and then applies it to the source we link, including where that source falls short.

This content is for informational purposes only and is not medical advice. Always consult a qualified healthcare provider before starting, changing, or stopping any medication.

NAD+ where to buy is a grade question before it is a price question, and almost every page ranking for it gets that backwards. Two vials can hold the same white powder at the same purity and be worth buying and not worth buying, because the thing that separates them is a manufacturing standard that never appears in the headline price.

Here is the listing this page keeps referring back to, so you can check the claims against it as you read.

First, NAD+ is not what most of this site is about

If you found this page from our GLP-1 coverage, start here, because the category difference matters to how you read everything below.

NAD+ is nicotinamide adenine dinucleotide, a coenzyme. A coenzyme is not a drug that acts on a receptor. It is a small molecule your cells already make and spend continuously, in this case as the electron carrier that moves reducing power through glycolysis, the citric acid cycle and oxidative phosphorylation, and as the substrate that sirtuins, PARPs and CD38 consume when they work ^[3]. Every cell in you contains it right now.

That makes it a different kind of purchase from semaglutide or tirzepatide, and a different kind from a research peptide too. NAD+ has no sequence at all, because it is not a peptide. It is sold in grams rather than the 5 mg or 10 mg vials the peptide market runs on, which is why a per-milligram price is meaningless here and everything below is quoted per 100 mg.

The evidence gap is the other thing to be direct about. The incretins this site covers arrived through randomized controlled trials with published endpoints. NAD+ has nothing comparable behind the way it is sold. The one human study of directly infused NAD+ we can point to was explicitly a pilot, published in 2019, and its authors noted that until then no data existed at all on what happens to infused NAD+ in people. What they found was that plasma NAD+ did not rise for the first two hours of a six hour infusion, because it was being cleared as fast as it went in ^[4]. That is a pharmacokinetics result, not an efficacy result, and there is no efficacy result to substitute for it.

So if you are tired on a GLP-1 and NAD+ has been sold to you as the fix, the honest position is that the fatigue is a real and common thing, covered in our page on how long GLP-1 fatigue lasts, and NAD+ is not a demonstrated answer to it. Buy it, if you buy it, understanding that.

The one FDA document that should change how you shop

In October 2024 FDA published a notice to compounders that is, unusually, directly about the thing you are searching for.

The agency said it was aware of compounders using food-grade nicotinamide adenine dinucleotide sold by repackagers to make intravenous products, and that 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" ^[1]. It then reported adverse event reports following use of NAD+ injectable drugs, including severe chills, shaking, vomiting and fatigue, some requiring medical treatment, and said those reactions were consistent with excessive levels of endotoxins ^[1].

Read that again with a buyer's eye. FDA is not describing counterfeits. It is describing real NAD+, correctly identified, at whatever purity the certificate says, that was manufactured to a food standard and then put into a syringe. Identity testing passes. Purity testing passes. The material is still wrong.

Endotoxins are fragments of gram-negative bacterial cell wall. They survive the things that kill bacteria, they are not removed by filtration in the way organisms are, and the test for them is separate from every test a purity certificate usually shows. FDA maintains its own guidance on pyrogen and endotoxin testing precisely because it is its own discipline ^[5].

NAD+ where to buy: the checklist, ordered by what it rules out

Each row rules out a different failure. The order matters because the top rows exclude problems that no amount of good behaviour further down can compensate for.

What to check	Why it rules something out	How you check it before paying
Grade stated on the listing	Food-grade material sold for injection is the exact failure FDA described	The listing or certificate should say pharmaceutical or research grade. A listing that says nothing about grade has not answered
Endotoxin or LAL result on the COA	Purity and identity say nothing about pyrogen load	Open the actual certificate and look for a bacterial endotoxins or LAL line, in EU/mg. If it is absent, ask
Lot number matching the batch you receive	A generic site-wide certificate describes someone else's material	Compare the lot on the certificate with the batch the listing names, then with the vial when it arrives
A named laboratory	Self-issued documents verify nothing	The lab should be an entity with an address you can look up
Quantity in grams, stated plainly	Vagueness about how much is in the vial is how per-unit price gets manipulated	The listing should name the milligram content, and the certificate should quantify it independently
Domestic stock and a dispatch cutoff	Long transit is a cold chain problem, not just a patience problem	A published cutoff time, then a first tracking scan in your own country
A refund policy you can read first	Recourse that exists only in a support ticket does not exist	Find the written terms on the site before checkout
No human-use claims anywhere	A research supplier making clinical claims is telling you it does not understand its own legal position	Read the product page and the footer

Nothing on that list requires expertise. All of it requires opening documents rather than reading a landing page, which is the actual work most buyers skip.

Scoring the source we link, including where it does not clear the bar

We link Ascension Peptides on this page and we earn a commission if you buy, which is disclosed on the card above and in our disclaimer. That is exactly why the scoring below is done against the checklist rather than around it.

The listing is NAD+ 1,000 mg at $104.00, which the code PEPTIDEDECK takes to $52.00, or $5.20 per 100 mg. Buying 3, 5 or 10 vials takes 3%, 5% or 10% off the list price separately, and free shipping starts at $250. Stock is domestic, orders before 2pm CST ship the same business day, and the listing is labeled for research use only with no human-use claims on it. That covers the bottom half of the checklist cleanly.

Rows two and five are where it gets interesting. Two independent laboratories publish batch certificates on this product, Kovera Labs on lot 25-05260628 and MZ Biolabs on lot 25-01260229. Open the MZ Biolabs document and you get purity by HPLC-UV at 99.66%, identity confirmed by HPLC-MS, and a measured quantity of 784.32 mg per vial against a 1,000 mg label, with the certificate's own note that salts and buffers present for solubility are not detected by UV and are not counted as impurities. Two named labs on lot-specific documents is more than most of this market publishes, and the quantification is a genuinely unusual thing to print.

What is not on that certificate is a bacterial endotoxins line. Neither purity nor identity testing addresses pyrogen load, so on the criterion FDA's own notice says matters most for anything destined for a syringe, the published documentation does not answer. Ask before you order, and treat the answer, or the absence of one, as information. We would rather tell you that than pretend a checklist we wrote ourselves gets a perfect score.

The regulatory position, which runs in NAD+'s favour and is still not approval

Peptide buyers arriving here will expect the usual answer, which is that no lawful prescription route exists. NAD is different.

FDA's interim policy sorts bulk substances nominated for compounding under section 503A into three categories. Nicotinamide Adenine Dinucleotide (NAD) sits in Category 1, "Bulk Drug Substances Under Evaluation", as does the reduced disodium form (NADH), on the list updated May 14, 2026 ^[2].

Category 1 means FDA "does not intend to take action against a compounder for compounding drugs using bulk drug substances listed in category 1, provided that the conditions described in the guidance document are met" ^[2]. That is non-enforcement pending evaluation. It is not approval, it is not permanent, and FDA says plainly that substances can be removed from category 1 if safety information warrants. There is no NAD entry in Category 2 at all, so if you have read that NAD+ is banned from compounding, that is simply wrong.

One trap worth knowing: Beta-Nicotinamide Adenine Dinucleotide Disodium Salt Trihydrate is a separate entry and sits in Category 3, nominated without adequate support, which is not eligible for the category 1 policy ^[2]. Same words, longer name, different position. Our NAD+ without prescription page works through what all of that means for a buyer rather than a compounder.

NAD+ where to buy comes down to one uncomfortable fact: the market sells you documents, and the document that would answer the most dangerous question is usually the one nobody publishes. Ask for the endotoxin result. If you want the same analysis run channel by channel instead of criterion by criterion, where to buy NAD+ does that, and best NAD+ source states a weighting before it picks anything.
