NAD+

NAD+ 1000mg — 10-Vial Pack is supplied as lyophilized powder under nitrogen. Typical reconstitution is in sterile or bacteriostatic water; the exact concentration depends on your protocol. Our free reconstitution calculator computes mL per dose and insulin-syringe units from any combination of vial size, water volume, and target dose.

Batch ND-2607 of NAD+ 1000mg — 10-Vial Pack is verified in-house at 99.0% HPLC main-peak purity, with molecular weight confirmed by LC-MS and endotoxin screened by LAL assay. That in-house COA — chromatogram, mass spec trace, and purity call — is bundled with your order as a downloadable PDF. Independent third-party re-verification can be arranged for a specific batch on request; it isn't run by default.

All orders ship via DHL, UPS, or FedEx from our China facility, insulated for transit, to 58 countries. Customs duties are prepaid by us (DDP) — no surprise charges on delivery. Estimated transit time is about 10–15 days door to door. Tracking number is emailed when the shipment is scanned by the courier.

One fully automated, self-serve method, 10% off: "Pay with crypto or card" at checkout takes a direct crypto payment from your own wallet (Bitcoin, Ethereum, USDT, USDC and more) or a normal card payment via our card-to-crypto processing partner — no crypto wallet needed for cards. Wire transfer, PayPal, and Revolut can be arranged by email before you order, at the regular price without the 10% discount. ACH is temporarily paused. Full payment-method details are on the shipping & payment page.

NAD+ is both air-sensitive and light-sensitive in solution. Best practice is to reconstitute immediately before use, refrigerate any leftover in opaque vials (preferably under nitrogen), and avoid repeated freeze-thaw cycles. Typical usable stability is 1-2 weeks refrigerated, much shorter than peptide products.

Yes — NAD+ and 5-Amino-1MQ are commonly studied together. 5-Amino-1MQ inhibits NNMT (nicotinamide N-methyltransferase), which is hypothesized to preserve NAD+ pools. Direct supplementation plus pool-preservation is a common combined approach. QSC stocks a bundled NAD+ + 5-Amino-1MQ stack.
