Custom vial sizes and labeling are where we actually start, not the standard 100mg, 500mg, or 1000mg you see listed — our company can do bulk synthesis for your own concentration or branding, and that’s what most serious buyers come for. The lyophilized powder holds up well during transit, and it's pretty much the standard form for keeping stability.
CAS 53-84-9, Janoshik verified, and the HPLC purity is typically above 98% depending on your run. One thing you don’t often think to ask: the powder can sometimes clump slightly if exposed to humidity, so we vacuum-seal each vial and pack with desiccant. Not a big deal, but worth knowing.

Storage is cool and dark — a fridge is fine, but avoid freezing unless you’re holding for months. We usually have stock for the 100mg and 500mg sizes, but the 1000mg vials often need a lead time of 2-3 weeks (confirm before ordering). Most buyers go with the 500mg for general research.
Also, this isn’t really suited for direct human use in its raw lyophilized form — you’d need reconstitution with bacteriostatic water or saline, and that step requires proper sterile technique. We don’t spin that as a positive; it’s just the reality of handling research-grade materail.
Better than reagent-grade NAD+ for metabolic assays or cell work, and the batch-to-batch consistency is tighter than what you’d get form a general chemcial suplier. Anyway, the MOQ on custom labels is about 50 vials or so, and we’ll send a COA with every shipment.
