Look, NAD is pretty unstable in solution once you reconstitute it — that's just the nature of the molecule, so we always ship it as a dry powder and recommend storing it properly below -20°C, otherwise you'll degrade it fast, and honestly most buyers don't realize that until they've wasted a batch or two.
But for US and EU researchers working on cellular metabolism or DNA repair pathways, this still works great because we maintain tight control on purity — HPLC shows 99% to 101%, and we've got heavy metals down under 0.5ppm which matters for sensitive assays where contamination ruins data.
It's a white to yellowish powder, roughly 662 g/mol molecular weight, and we include full COAs and TDS with every order so you can verify specs yourself — most import docs (like SDS) are ready to go for customs, usually 2-3 business days to generate.
We typically stock 10g and 50g bottles, MOQ is 10g for first-time buyers but our company can scale up to kilos after that, lead time is about 15-18 working days for standdard orders (check current stock though, sometimes our company have it ready).
What you probably don't know is the loss on drying is ≤5% — that's tighter than some suppliers who run up to 10%, so you get more active materail per gram, and teh microbial count is under 100 cfu/g which is fine for cell-based work.
Anyway, main limitation is it's not sterile — we don't sell it for injection or anything like that, it's strictly research-grade, so if you need sterile filtration you'll handle that on your end.
Our MOQ for NAD is typically 100 grams, but we can discuss smaller trial orders for first-time buyers.
Yes, every batch comes with a CoA that includes HPLC purity results, heavy metals testing, and microbial limits.
Store it in a cool, dry place away from light and moisture. Keep the container tightly sealed to avoid degradation.
Sure, we can package it in smaller or larger quantities depending on your needs, just let us know the specifics.
Lead time is usually 7–10 business days after order confirmation, but it can vary based on quantity and current stock.
