Two NAD+ listings both say 99% pure. Is one better?

Possibly, and purity will not tell you. Purity is a ratio within the powder. Grade describes the manufacturing standard, including bioburden and endotoxin control, and that is the axis FDA's food-grade notice is about. Identical purity figures are compatible with completely different materials.

What does a repackager actually do?

Buys bulk material and puts it into smaller labeled containers. It is legitimate work when the material and destination match. FDA's concern is food-grade NAD+ moving through repackagers into intravenous compounding, and it asked repackagers to label food or supplement intent clearly.

Should I worry that a certificate reports less than the label weight?

Read it carefully rather than reacting. The certificate above measures 784.32 mg against a 1,000 mg label by HPLC-UV, and states that salts and buffers are not visible to that method. Use the measured figure if you want the conservative price per 100 mg, and ask the supplier what accounts for the difference.

Is NAD+ for sale legally in the US?

Selling it as a research chemical labeled for laboratory use is a different activity from selling a drug for human use, and the two get conflated constantly. The legal detail sits on [NAD+ without prescription](/nad/nad-without-prescription/).

Does any of this apply to NAD+ supplements?

Not really. Capsules sold in the supplement aisle are usually precursors rather than NAD+ itself, sold under a separate regulatory framework we have not covered here, and they are a different purchase from a gram of powder in a vial.

NAD+ for Sale: Food Grade and Pharma Grade Look Alike

Summary: Two listings can show identical purity figures and describe materials that belong in completely different places. This page reads an NAD+ listing field by field, using FDA's own food-grade warning as the reason each field is there.

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+ for sale is a phrase that covers two products which look identical on a listing page and are not remotely the same thing. Both are white powder. Both can honestly claim 99% purity. One was made to a food standard and one was not, and no photograph, purity figure or price tells you which is which.

The listing referenced throughout this page is below, so the fields can be checked against a live example rather than a hypothetical one.

Where readers actually buy it

The compound, before the listing

NAD+ is nicotinamide adenine dinucleotide, a coenzyme. Not a peptide, not a hormone, not a GLP-1. It is a molecule your cells already synthesise and consume continuously, carrying electrons through glycolysis, the citric acid cycle and oxidative phosphorylation, and acting as the substrate that sirtuins, PARPs and CD38 use up when they work ^[4]. Buying it is not like buying a drug that binds a receptor. It is buying a metabolic component in bulk.

Two consequences for how you read listings. First, it is sold in grams, not the 5 mg and 10 mg vials the research peptide market runs on, so per-milligram pricing is a distraction and everything here is quoted per 100 mg. Second, the evidence standard is nothing like the approved incretins this site normally covers, where the argument is between two products with published randomized endpoints, as in choosing between GLP-1 medications. NAD+ is bought on mechanism and hope. Say that to yourself once before you spend.

What NAD+ for sale often means: a repackager in the middle

FDA published a notice to compounders, content current as of 30 October 2024, that describes this market more accurately than most of the market describes itself.

The agency said it was aware of compounders using food-grade nicotinamide adenine dinucleotide sold by repackagers to make intravenous products ^[1]. Sit with the middle of that sentence. Repackagers. Not manufacturers of pharmaceutical-grade material, but businesses buying bulk food-grade powder and putting it into smaller containers with new labels. That is a real and legal business when the destination is a food or a supplement. It becomes a problem when the containers end up in a sterile compounding suite or a syringe.

FDA's reason: 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]. And then the consequence, in the agency's own words: adverse event reports following use of NAD+ injectable drugs including severe chills, shaking, vomiting and fatigue, some requiring medical treatment, with reactions consistent with excessive levels of endotoxins ^[1].

Endotoxins are fragments of gram-negative bacterial cell wall. They are heat-stable, they are not what a purity assay looks for, and testing for them is a separate discipline with its own FDA guidance ^[2]. This is why a listing can be entirely truthful about purity and still be selling you the wrong material.

FDA also asked repackagers to clearly label ingredients intended for food or supplement use ^[1], which is a quiet admission that today many do not. If the manufacturer upstream is not labeling grade, the storefront downstream is unlikely to invent it.

What a real NAD+ listing states, field by field

Field	What a serious listing shows	What an evasive one does instead	Why the difference matters
Grade	Names the standard the material was made to, or at minimum states research grade and nothing about human use	Silence, or a wellness photograph	This is the exact axis FDA's notice is about
Quantity	A milligram figure, and ideally an independent quantification of it	A vial photo and a product name	You cannot price anything per 100 mg without it
Lot number	A batch number that matches the certificate on the page	A certificate with no lot, or one lot for every product	An unmatched certificate describes someone else's material
Testing scope	Names each assay: HPLC for purity, MS for identity, and separately any endotoxin or bioburden work	The words third-party tested with no document behind them	Purity and identity do not answer the sterility question
Laboratory	A named lab you could look up	Unbranded PDFs	Self-issued documents verify nothing
Storage	States how the sealed vial should be kept	Nothing	Handling is part of what you are buying
Use statement	Research use only, no human-use claims anywhere	Dosing tables, protocols, before and after photographs	A seller making clinical claims does not understand its own position

The pattern in the right-hand column is not deception exactly. It is omission, which is cheaper and harder to complain about.

Reading an actual certificate

Abstract advice is easy to agree with and hard to apply, so here is the document on the listing above, read properly.

Two independent laboratories publish batch certificates on this product: Kovera Labs on lot 25-05260628, and MZ Biolabs on lot 25-01260229. Opening the MZ Biolabs certificate gets you four things. Purity by HPLC-UV, reported at 99.66% with the peak list printed. Identity confirmed by HPLC-MS. A quantification by HPLC-UV giving a measured 784.32 mg per vial against a 1,000 mg label. And a note from the laboratory that salts and buffers present to aid solubility and buffer pH are not normally detected by UV and are not counted as impurities.

Three observations, in order of usefulness.

Publishing a measured quantity at all is unusual, and it is the kind of number most sellers would prefer not to print. Read it for what it is, which is how much NAD+ the UV method saw, with the laboratory's own caveat that non-chromophoric excipients are invisible to it. It is not proof of a short-filled vial and it is not confirmation of a full one.

It does change the arithmetic if you want the conservative version. At $52.00 with the code, the label figure gives $5.20 per 100 mg. Against the measured 784.32 mg, the same $52.00 works out at about $6.63 per 100 mg. Both numbers are defensible and the second is the one a careful buyer should carry into any comparison. Our NAD+ price page runs the full comparison.

And the thing that is not there: no bacterial endotoxins line, on either the purity page or the identity page. That is standard for research certificates and it is still the gap that FDA's notice is about. Ask the supplier directly, including this one, and treat a non-answer as an answer.

NAD+ vials for sale is not the same search as NAD+ injection for sale

Worth separating, because the results overlap and the products do not.

Searching NAD+ vials for sale lands on research suppliers selling sealed powder, labeled for laboratory use, priced per vial. That is what the listing on this page is.

Searching NAD+ injection for sale is a different market. A ready-to-use injectable NAD+ preparation is a compounded drug, which in the US means a 503A pharmacy working against a prescription under FDA's interim policy. NAD does sit in Category 1 of that policy, "Bulk Drug Substances Under Evaluation", on the list updated May 14, 2026, where FDA states it "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" ^[3]. That is non-enforcement pending evaluation, not approval, and not a licence for a storefront. Anyone selling a finished injectable NAD+ product to the public without a prescription is not operating inside that policy. Our buy NAD+ injection page deals with the format question directly.

NAD+ for sale rewards the boring skill of opening documents. Grade, lot, quantity, testing scope, and whether anybody ran an endotoxin assay: five things, none of which require a chemistry background, and four of which most listings will simply not contain. If you want those five turned into an ordered checklist you can score a supplier against, NAD+ where to buy does that, and best NAD+ source states a weighting before naming anything. The same boring skill turns up numbers a seller had no reason to publish, which is how a Selank vial assayed at 12.29 mg against a 10 mg label became the useful fact on that listing.
