Sourcing NAD+ in Bulk: A B2B Guide to Wholesale and White-Label Supply in the EU

For distributors and research-supply resellers, NAD+ (nicotinamide adenine dinucleotide) has become one of the most requested references in the longevity-research category. If you are building or expanding a catalogue, the sourcing decision comes down to three practical questions: where the stock physically sits, how it is verified, and whether you can put your own brand on it. This guide is written for B2B buyers, not end users, and every reference to NAD+ here concerns a laboratory research reagent (Research Use Only), not a product for human or animal consumption.

Why EU-held stock changes the math

The single biggest variable in wholesale peptide sourcing is where inventory clears customs. When stock is held outside the EU, every order becomes an import event: customs paperwork, VAT handling, unpredictable clearance times and the risk of seized shipments. Peptworks holds NAD+ 500 mg lyophilised vials inside the EU, so orders move intra-community and arrive in roughly 3-5 business days with no customs step. For a reseller, that means predictable lead times you can actually promise your own customers.

Bulk vs. white-label

There are two ways to buy. Bulk means unbranded vials, ideal if you repackage or supply other labs directly. White-label means the vials are labelled with your own brand and boxed, so you can present a finished, shelf-ready product without running your own filling and labelling line. A one-time label setup fee of EUR180 applies to orders under 100 units and is waived from 100 units onward, which makes the white-label route increasingly efficient as volume grows.

Reading the price ladder

Peptworks publishes per-vial pricing openly, with discounts tied to the combined volume of the whole order rather than per-line quantities. For NAD+ 500 mg the tiers are: EUR21.00/vial at 100 units, EUR17.22 at 300 units (-18%), EUR15.75 at 500 units (-25%) and EUR14.28 at 1000 units (-32%). The discount is a single tier set by your total combined units; it is not stacked. The minimum order is 10 units (one box) per reference, with vials shipping in boxes of 10, so you can trial a reference before committing to a volume tier.

Verification your customers can check themselves

Quality documentation is where a serious supplier separates itself. Every NAD+ batch ships with an independent Certificate of Analysis covering HPLC purity (>=98%) and heavy metals. The box carries a unique QR code that links directly to that batch's CoA, verifiable through Peptworks. This matters commercially: your own buyers can scan and confirm authenticity per lot, which reduces support friction and builds trust in your brand without you having to vouch for chemistry you did not run yourself.

Payment and operational fit

Settlement is by USDC bank transfer against an invoice; there is no card checkout, which aligns with how most B2B procurement and accounting workflows actually operate. The full catalogue is available in 10 languages, so multi-market resellers can source and reference documentation consistently across the EU.

The bottom line for resellers

If you are sourcing NAD+ to resell, the combination that de-risks your operation is: EU-held stock for fast, customs-free delivery; transparent volume pricing so your margins are predictable; per-batch, QR-verifiable CoAs so authenticity is provable; and a white-label path so you can grow a branded catalogue without capital-heavy infrastructure. Start with a small qualifying order, verify the CoA, then scale into the volume tier that fits your demand. Remember throughout that NAD+ supplied in this channel is a research reagent for laboratory use only.
