NAD+ Wholesale: A Sourcing Guide for Research Suppliers

What NAD+ Is, on Paper

NAD+ is listed as a dinucleotide coenzyme: nicotinamide adenine dinucleotide, also catalogued as nadide, beta-NAD and coenzyme I. A supplier's product page should give its identity data (name and synonyms, CAS number, molecular formula, molecular weight) and cite where that data comes from. Our NAD+ wholesale page lists CAS 53-84-9, the formula C21H27N7O14P2 and a molecular weight of 663.4 g/mol, sourced to PubChem.

Because it is not a peptide, we file NAD+ in the small molecules and cofactors class rather than with the peptides. Describe it the same way in your own catalog: what the material is, never what it does. Research-use-only copy is covered in writing storefront copy for research-use-only products.

Names You'll See on Quotes and Labels

NAD+ travels under several names, and different documents in the same order may use different ones. A quote might say NAD+, a label nadide and a report nicotinamide adenine dinucleotide. Those all describe the same compound, but only if the CAS number and the identity result agree.

Related cofactors are a different matter. The reduced form, NADH, and the phosphorylated forms, NADP+ and NADPH, are separate materials with their own identity data. A listing that drops the plus sign or adds a letter may be describing one of them, or may simply be loose naming. Treat any mismatch as a question for the supplier, in writing, before you order.

• Match the CAS number on the quote and the product page with the one on the report, where the report gives it.
• Match the name on the label to the name on the report, or keep a note of which synonym each document uses.
• Match the measured mass on the identity result to NAD+, not to a related cofactor.

Sizes and Form

NAD+ is usually supplied as lyophilized powder in single vials, and it is sold in far larger amounts per vial than most peptides. We list it in 500 mg and 1,000 mg vials. Labels and quotes from different suppliers may write the larger size as 1,000 mg or 1 g; they are the same amount, but make sure every document you hold uses the size you are actually ordering.

Count by vial, not by total weight. An order for 10 g could mean ten 1,000 mg vials or twenty 500 mg vials, and those are priced, labelled and documented differently.

Ask for the size you need even if it isn't listed. Other sizes and larger factory-direct runs can often be quoted.

What the Report Should Show

The reports published for our NAD+, one for each listed size, are on its product page, each linked to the laboratory's own document. How to read a peptide certificate of analysis walks through each line; the same reading applies to a cofactor report.

• The product and labelled size, matching what you're buying. A 500 mg report doesn't document a 1,000 mg vial, so expect one report per size.
• A batch or lot number, the same one printed on your vials.
• HPLC purity, with the method and the detection wavelength. The wavelength is chosen for the compound, so on an NAD+ report it may differ from the one on your peptide reports.
• Identity by mass spectrometry (LC-MS), confirming the measured mass matches NAD+.
• Net content, if the laboratory measured it: the amount found in the vial, set against the labelled size.
• The laboratory's name and a way to verify the report with them.

Why Net Content Matters More at Large Sizes

On a 1,000 mg vial, the gap between powder weight and compound weight is a much larger absolute amount than on a small peptide vial, so it is worth knowing which one the labelled size refers to. Ask the supplier in writing whether the size on the label is the weight of powder or of NAD+, and whether net content was measured on the lot you'll receive.

HPLC purity and net content answer different questions, and one does not stand in for the other. HPLC purity vs. net peptide content explains the difference; the same reasoning applies to a cofactor.

Research Publication Statistics

If you want a sense of how widely NAD+ appears in the published literature before you add it to a catalog, our NAD+ research statistics page shows how much has been published, by year and study type, with the PubMed search shown so you can run it yourself. It describes the literature, not the material in any vial, and it makes no claim about what the compound does. Other compounds are listed on the research hub.

Comparing Wholesale Quotes

Put quotes side by side for the same sizes, vial counts and documents: the lot and its report, labels, shipping and how long the price holds. A low price with no named lot is not a like-for-like quote. How wholesale peptide pricing works explains what moves the price.

Our wholesale stock ships from Tampa Bay, Florida, to addresses in the United States, and factory-direct orders can ship internationally. Every wholesale lot comes with a certificate of analysis. We don't publish a minimum order, so ask about the quantity you have in mind.

If the vials will carry your own brand, ask for that in the same quote: the label, the lot printed on each vial and the research-use-only statement. White label explains how it works.

Questions to Ask Any NAD+ Supplier

• Which lot will I receive, and can I see its report before I pay?
• Is there a separate report for each size I'm ordering?
• Does the labelled size mean powder weight or NAD+ weight?
• Was net content measured on this lot, and by which method?
• Which laboratory issued the report, and how can I verify it with them?
• How long does the quoted price hold, and what is the quoted lead time?

When the Order Arrives

Check the delivery before it goes into stock. Count the vials by size, confirm that every vial shows the lot named on your quote, and check that the report for that lot names the same product and labelled size. Look for intact seals and legible labels, and photograph anything that doesn't match before you contact the supplier. What lyophilized powder means when you buy peptides wholesale has a fuller receiving checklist.

Getting a Quote

Add NAD+ to your list in the catalog, pick the size, and send the list on WhatsApp or by email. We reply with pricing, and the quote names the lot you'll receive and its report, so you can check it before you pay. If you need a compound we don't list, add a note to the same message: we source beyond the catalog.
