Where to buy NAD+ (nicotinamide adenine dinucleotide) in the UK: the sellers with a verifiable COA

The newest verifiable NAD+ certificate on any UK seller's website is on Biohackpeptides (biohackpeptides.co.uk), analysed 8 Sep 2026 (task #227610 on Janoshik's site); 9 verified sellers hold one covering NAD+, listed newest first below. Of the 450 active UK sellers we audit, 38 (8%) publish their own verifiable Janoshik certificate of analysis, and this page lists which of them hold one covering NAD+, newest certificate first. It is a record of paperwork, not a recommendation: The Peptide Watch sells nothing, takes no money from sellers and links to none of them. NAD+ is not a peptide at all but a coenzyme every living cell makes; UK research-peptide shops sell it as a powder for injection alongside their peptides. Because it degrades readily, a certificate that states the amount actually recovered from the vial matters more than the label. Purity and identity cannot be judged by eye, so an independent certificate you can check is the only real proof of what is in the vial.

The one test that matters for NAD+

Ignore the marketing. The question is simple: does the seller publish a verifiable Janoshik certificate that names the seller itself as the client? If it does, you can confirm an independent lab tested that batch. If it shows an in-house document, a borrowed certificate, or "COA on request", you cannot. Learn the two-minute check in how to verify a Janoshik COA.

Which UK sellers publish a verifiable COA

Of the 450 active UK research-peptide sellers we audit, only 38 (8%) publish their own verifiable Janoshik certificate. Any of them is where you can actually verify testing, for NAD+ or any compound. A few: Lab77Peptides · Peptology Labs · Biovanta · Camo Chem · Biohackpeptides · Zenic Labs. See the full independently-tested list, or check a specific shop's certificate with the free COA Checker.

Audit findings, not recommendations. Every entry is a report covering NAD+ that we opened on Janoshik's own site and that names the seller itself as the client; the date is the analysis date printed on the report where we have read it, otherwise the date the laboratory received the sample. The table below is the same ledger in full, so the two always agree. Not exhaustive: a vendor whose NAD+ report we have not yet read is not listed.

The 13 verifiable NAD+ certificates we have read, newest first

Each row was opened on Janoshik's own site by a real page load and transcribed. The client column is the name the laboratory printed; a certificate counts as a seller's own only when that name is the seller. The report date is the analysis date printed on the report where we have read it, otherwise the date the laboratory received the sample. The verify link opens the laboratory, never the shop. Audit findings, not recommendations.

What the 13 NAD+ certificates show

We have read 13 Janoshik reports covering NAD+, published by 9 UK sellers. Each was opened on Janoshik's own website. All 13 name the seller itself as the client. 9 of the 13 are dated within the last six months and 2 are more than a year old. The newest is dated 8 Sep 2026 and the oldest 15 May 2025.

A certificate is a batch document. The lines that matter are the compound (it must say NAD+, not only a batch code), the client (the shop, not its supplier) and the analysis date. A new batch is untested until a new report appears.

NAD+ in the UK at a glance

Counted from the vendor ledger at build time: a seller is included when its audit records NAD+ in its certificates or its catalogue notes. Audit findings, not recommendations.

The other 35 sellers: what they publish instead

• No named lab, nothing to verify: 21
• 'COA on request', nothing published: 2
• No testing claim found: 2
• Shows a supplier's certificate, not its own: 1

• No verifiable third-party testing; mixed peptide/steroid catalogue: 1

Each pattern is explained on the seller's own audit page, with what we saw and the date. The A-Z directory lists every seller.

The market for NAD+ in the UK

Advertising. Google's Ads Transparency Centre shows 3 of these sellers running ads: Peptifyuk, Kensingtonlabs, Thoroughbredlabs. Paid reach is where a new buyer meets a brand before meeting any certificate.

Companies. 12 of the 45 can be matched to a Companies House record; the median company is 10 months old and 7 were incorporated within the last year. A seller with no traceable company is not necessarily dishonest, but there is nobody to hold to its certificate.

Reviews. 8 of the 45 have a Trustpilot profile with a score; the median is 4.7, 5 sit at 4.5 or above and 0 below 3.0. A review score says who collects reviews, not who tests, which is why it sits next to a certificate and never instead of one.

What the research shows for NAD+, and what it does not

A coenzyme, not a peptide, with a literature that is mostly about its precursors. PubMed indexes 3,005 papers on NAD+ supplementation or infusion, 1,619 of them in rodents, and 69 clinical-trial reports; almost all of those trials gave oral precursors, nicotinamide riboside or nicotinamide mononucleotide, not NAD+ itself. ClinicalTrials.gov lists 264 registered trials on the same terms, again dominated by precursors.

Injected NAD+ has almost no controlled evidence and no licence anywhere. Trials of intravenous or subcutaneous NAD+ are few and small. No regulator has approved NAD+ as a medicine; UK drip clinics supply it as an unlicensed product, and in the United States it exists only as a compounded preparation.

What a certificate can tell you here. NAD+ degrades readily in solution and on storage, so the useful number on a report is the amount actually recovered. The reports we read recovered between 102 mg and 554 mg per vial across four sellers, which is why the figure, not the label, is what to read.

Who owns NAD+, and where it stands

Counts are from PubMed on 15 September 2026 using the queries recorded in our evidence file; "clinical trial" is PubMed's own publication-type index. This is a description of the published record, not medical advice and not an argument for or against use.

The Peptide Watch's position on NAD+

Not a licensed medicine in the UK; supplied by drip clinics as an unlicensed product and by research-chemical sellers as a powder. The Peptide Watch reads the certificates UK sellers publish and does not recommend anywhere to buy NAD+. Sellers on this page are listed by the date of their newest NAD+ certificate and by nothing else. If you can verify a seller's testing, you can at least judge its evidence; if you cannot, you are taking the seller's word for what is in the vial.
