Where is the NAD+ COA and lot number?
Every NAD+ lot has a third-party Certificate of Analysis (COA) that you can find by the lot number printed on the vial label. Search the lot or accession number in the Simple Peptide COA archive; the COA for the lot on your label is the controlling document.
Most recent NAD+ COAs in the archive as of October 9, 2026:
- NAD+ lot NAD 1000-092026-2, reported September 19, 2026, 99.94% purity on the COA (view COA)

How does NAD+ ship?
NAD+ orders placed before 2:00 PM ET, Monday through Friday, ship the same day via 2nd Day Air. Orders placed after the cutoff are not guaranteed to ship the same day.
P.O. Box orders ship via USPS, and Simple Peptide ships to U.S. addresses only. Ordering NAD+ requires a verified account (21+). Returns of unopened, unused NAD+ follow our Shipping & Returns policy.
How does NAD+ compare with NAD+ (Buffered)?
Choose the larger vial for the lowest cost per mg, the smaller vial for a smaller quantity, or NAD+ (Buffered) if your protocol calls for a buffered formulation. All three have lot COAs in the same archive.
