Usually ships within 5-7 business days of order placement, and delivrey takes roughly 7-14 days depending on your location and the shipping method selected at checkout — we've seen some internatioanl orders clear customs in about half that time when paperwork's in order.
It's a white crystalline powder that's water-soluble, and the sealed vials come under inert gas so moisture doesn't get in there while it's sitting on the shelf. We're seeing most buyers request the 250mg or 500mg vials, but the 1g size is a pretty common pick for those running longer-term metabolic studies or aging research protocols.
What it does is act as an electron carrier in redox reactions, which basically means it's crucial for shuttling electrons during cellular respiration and ATP production — those energy pathways that decline noticeably with age. Many researchers use it to study how NAD+ supplementation affects sirtuin activation, though you won't see sirtuins listed 's COA from the HPLC and MS verification we run.
Purity checks in above 99% by HPLC, typically between 99.2% and 99.5% across recent lots, and each vial ships with its own COA and signed data sheets for both MS and NMR confirmation. 663.43 g/mol molecular weight comes through consistently in our testing.
Storage is at -20°C in dry conditions — don't let it sit at room temp for more than a few hours, or you'll see some degradation within 2 years of teh manufacture date. Also, we usually have stock, but confirm lead time for orders over 100 vials; that's when our supply chain can get a little stretched.
One thing buyers don't always ask about: the powder tends to clump if exposed to humidity for even a short time, so open vial quickly and reseal immidiately. It's not suited as a reagent for in vivo application without further formulation — we label it 'for research use only' because that's exactly what it's made for, not therapeutic compounding straight out of the vial.
