So you're doing NAD+ research and you've probably seen those cheaper alternatives floating around—the ones that claim 98% but come back at 96% on the COA if you actually push for an HPLC run, and we've had customers send us competitor samples for testing more than once, basically confirming what we suspected all along.
What we're supplying here is the 53-84-9 CAS, the real deal with a molecular weight of 663.43, and we hold it consistently above 98% —better than reagent grade for this kind of work, and the solubility in water is excellent, which matters when you're reconstituting for those or whatever your protocol calls for.

One thing buyers don't always think to ask is how hygroscopic this stuff actually is—it's light sensitive too, so we ship it in amber vials with desiccant, and you'll want to store it at -20°C in a dry enviornment or you'll lose potency faster than you'd expect, usually within a few months if you're careless.

For most labs we see, the 5g drum is easier to handle than the 1g vials, but if you're running pilot studies or just testing a new pathway, the smaller size is fine—we also do bulk packaing if you need 50 units or so for a larger project, and the lead time on custom orders is about 20 days or so (check with us first if you're on a tight timeline).

We include a full COA with every order, and the USP/EP testing specs are met across teh board—but honestly, this isn't suited for anything except research, so don't ask about human use because our company can't and won't support that, it's just a fact of the regulatory.
Anyway, when you order form us, you're getting the documentation upfront, no back-and-forth requests for the HPLC trace, and we usually have stock on the common sizes so you're not waiting weeks for a reshipment.
We can do single 1g packs if you're just testing, but our standard MOQ for bulk pricing starts at 10g. Feel free to reach out if you need a custom amount.
For a 10g order, we usually ship within 5 to 7 business days after payment confirmation. Larger bulk orders may take a bit longer depending on stock.
Yes, every batch comes with a CoA that includes HPLC purity data and verification it meets ≥98% purity. We can also supply USP/EP test results if requested.
Absolutely, we offer bulk packaging tailored to your needs. Just let us know the quantity you require, and we'll quote accordingly.
Keep it at -20°C in a dry environment, and always protect it from light since it's light sensitive and hygroscopic. That'll keep it stable for the full two years.
