So a researcher somewhere is running a study on mitochondrial function in aging cell lines, and they’ll reconstitute this lyophilized powder in water at 5mM or 10mM depending on their protocol—it’s the kind of thing where you want to be sure every vial matches that 98% purity or better, because batch-to-batch variation can throw off weeks of work.
We run HPLC before it leaves, and teh COA will show you the retention time and area percent—usually it’s right around 99.2% for most runs, but we call it ≥98% to be safe, and we’ve got the raw data if you need to audit it.

One thing that catches buyers off guard is storage—you really do need to keep it at -20°C in a dark, dry place, because NAD+ degrades faster than most people think at room temp, and we usually have stock but confirm lead time if you’re ordering over 500 vials or so.

The 100mg vials are pretty much the standerd for small-scale work, but if you’re doing across multiple timepoints, the 500mg or 1000mg vials cut down on reconstitution errors, and we can do custom MOQs if you need a different split.
We also offer a retest policy within 30 days of receipt if the powder doesn’t look right—white to off-white is what you’ll see, but if it’s yellow or clumpy, that’s a red flag, and we’ll swap it out (usually within a week or so).
Our NAD+ vials are lyophilized powder with ≥98% purity, and yes, we can provide a Certificate of Analysis with each batch upon request. Just let your sales contact know.
The smallest package we offer is 100mg per vial, but since our MOQ is customizable, you can order just one vial if that's what you need for your research. No forced bulk commitments.
Standard lead time is 3-5 working days from order confirmation, even for the 1000mg vials. We maintain large production capacity, so stockouts are rare.
Yes, we ship with insulated packaging and ice packs to keep the product cool during transit. Once received, store the vials in a -20°C freezer, away from light and moisture.
Absolutely, our MOQ and package sizes are customizable - we can do specific vial sizes or custom labeling for your project. Just share your requirements and we'll work out the details.
