Best NAD+ Suppliers in 2026: 45 Sellers, Priced by the Gram

Panda Peptides lists a 500mg NAD+ vial at $38.39. The priciest 500mg vial on our board is $204.70. Same coenzyme, same quantity, and a $166 gap.

We priced NAD+ at all 45 vendors carrying it in our August 10 refresh. Verified Peptides, Panda Peptides, Peptidology, Orbitrex Peptides, and Penguin Peptides are the five we would point people to. The market median is $0.125 per mg, so anything under a dime per mg is a genuinely good number, and the sellers hitting it are mostly the same ones publishing independent lab work.

NAD+ is the one thing on the shelf you buy by the gram

Most of what we price ships in 5mg and 10mg vials. NAD+ is a coenzyme, so the default vial in our data is 500mg, and a third of the sellers list a full gram. That changes the arithmetic. A penny per mg is a rounding error on a 10mg vial of BPC-157 and it is ten dollars on a gram of NAD+.

Here is where the market sat in our latest run:

The full sortable table lives on our NAD+ vendor page, and every number on it is normalized per milligram on the price index for exactly this reason.

The vial size moves the price more than the seller does

Penguin Peptides prices three sizes: $30 for 100mg, $65 for 500mg, $97 for 1000mg. Run the per-mg math and that is $0.30, then $0.13, then $0.097. Same shop, same week, and the small vial costs three times as much per milligram as the gram.

NuLife Peptides shows the same shape at $90 for 500mg against $125 for 1000mg, so $0.18 versus $0.125. Peptide Technologies is the exception worth naming: $59.95 for 500mg and $119.95 for 1000mg, flat at $0.12 either way, which is unusually straight pricing.

So size up when you can, with one caveat. Reconstituted material has a clock on it, so buy the vial you will realistically finish. Our storage and reconstitution guide covers how long you actually have.

The five we would use

We weight independent third-party lab testing heaviest, then price per mg, US shipping, reputation, catalog depth, and payment options. The whole rubric is public in how we score vendors. Here is where it lands for NAD+.

Verified Peptides: the cheapest US-shipping price we can confirm

$71.40 for 1000mg, which is $0.071 per mg and the best number on our board from anyone shipping domestically. Finnrick handles the testing, the most rigorous lab source we track, and Verified Peptides carries one of the highest scorecards we keep. Credit card only, and one gram at that price is the easiest recommendation in this whole category. Full scorecard.

Panda Peptides: the cheapest 500mg vial anywhere

$38.39 for 500mg, so $0.077 per mg. Janoshik tested, ships to US addresses out of the Greater Toronto Area, and the payment list is the widest of the group: Apple Pay, Google Pay, CashApp, Zelle, bank transfer, and card. For a half gram, this is the value pick by a wide margin. Full scorecard.

Peptidology: the best paper trail on the board

$82.99 for 1000mg, which is $0.083 per mg, comfortably under the median. Scottsdale, Arizona, Finnrick COAs, and four payment rails including ACH and Zelle. Peptidology carries the strongest scorecard of any vendor we track, and pairing that with a below-median price is rare enough that it earns a spot even when two sellers undercut it. Full scorecard.

Orbitrex Peptides: the Finnrick-backed half gram

$54.99 for 500mg, or $0.11 per mg, shipping from Flower Mound, Texas, with Finnrick testing and card or crypto at checkout. Orbitrex sits in the top three of our board, and this is where we would go for a 500mg vial with top-tier lab work behind it. Full scorecard.

Penguin Peptides: the low-commitment first order

$30 for 100mg is the cheapest way we know to watch how a shop handles packaging, cold shipping, and paperwork before committing to a gram. Janoshik tested, and the payment list includes PayPal alongside ACH, bank transfer, and Zelle, so recourse exists if a first package goes sideways. Once a shop earns your trust, their gram is $97. Full scorecard.

Also worth a look: Zenith Biopeptides out of Columbus, Ohio lists 500mg at $50 with MZ Biolabs testing. SimplePeptide ships from Florida at $65 per 500mg on Freedom Diagnostics COAs. Atomik Labz in Alexandria, Virginia runs $109 per gram, Finnrick tested, and takes Venmo alongside card and crypto.

NAD+ sits in a friendlier FDA bucket than most of this shelf

This one surprised us when we went and checked. On the FDA's list of bulk drug substances nominated for compounding, updated May 14, 2026, Nicotinamide Adenine Dinucleotide (NAD) appears in 503A Category 1, the bucket labeled "Bulk Drug Substances Under Evaluation." FDA states it does not intend to take action against a compounder using a Category 1 substance when the conditions in its guidance are met.

Most of the popular research catalog sits somewhere else. FDA has published safety writeups covering BPC-157, TB-500, Epitalon, MOTS-c, Melanotan II, Selank, Semax, and Thymosin Alpha-1 on its Category 2 page. NAD+ is absent from that page entirely.

The list keeps moving, and generally in an interesting direction. FDA has said it intends to consult the Pharmacy Compounding Advisory Committee before the end of February 2027 about adding GHK-Cu to the 503A bulks list. Two housekeeping notes that stay true regardless: NAD+ injections are still awaiting FDA approval, and anything you buy through a research supply channel is labeled for laboratory research use.

What the human data actually shows

Here is the honest state of the evidence. An October 2025 review in Nature Metabolism (Vinten and colleagues, volume 7, pages 1974 to 1990) walked through the clinical trials on NAD+ precursor supplementation in human ageing and landed on limited efficacy, cautioning that rodent results translate to people poorly. Animal work here is genuinely promising and the human trials are thinner than the marketing around them.

That is a reason to care about what you actually receive. If a seller publishes a certificate from a named independent lab, matched to the product and the batch you are buying, you at least know what is in the vial. Our guide to reading a peptide COA walks through the 60 second version, and the full vendor comparison shows which of the 72 shops we track publish one.
