What separates this from cheaper NAD+ is the documentation trail—every batch ships with a COA from an independent lab, not just the manufacurer’s in-house HPLC, and we’ve seen consistent purity at 99.1% or so across the last five lots we moved.
You’re looking at lyophilized powder in 250mg or 500mg vials, and the water content sits under 0.2% by Karl Fischer, which matters because even trace moisture accelerates degradation at -20°C storage—basically, it keeps for the full 24 months if you don’t open it under humid conditions.
Heavy metals are undetectable for arsenic, cadmium, and mercury, with lead at <10 ppm, and the pH of a 1% solution runs 5.3, which is tighter than most generic suppliers hold—we’ve had buyers use this for enzymatic assays without buffer adjustments.
Shiping is typically via insulated containers with dry ice for internatioanl orders, but we usually have stock in regional warehouses, so confirm lead time if you need it in under 10 days—transit from main depot runs about 7-14 business days to most destinations.
Payment terms are net 30 on orders over $2,000 USD after credit approval, otherwise wire transfer or credit card with a 3% surcharge (check with your AP team on that), and MOQ is 10 vials per size, though we can split a case of 50 if you need mixed quantities.
It’s not suited for in vivo work without further purification—the grade is research use only, so don’t expect sterile fill or endotoxin testing on the vials, but for cell culture or enzymatic studies, it’s actually cleaner than some pharmaceutical-grade batches we’ve seen from other sources.
