NAD+
Lyophilized, 500 mg, in a 10 mL vial, sealed.

Presentation
What is in the vial, how much, and how it is sealed.
“Oxidized form” is part of the identity rather than a qualifier: the reduced form is a different substance with a different mass.
NAD is supplied here as nicotinamide adenine dinucleotide, oxidized form, free acid, a sterile lyophilized powder, 500 mg to the vial.
It is filled at 500 mg, sealed, as a white to off-white lyophilized powder. The molecular formula and the average mass are the figures the identity test is run against.
As filled
Standard GB‑24Identity is settled before purity.
Which substance it is, and how much of the lot is that substance.

The name is structural: two nucleotides, one carrying nicotinamide and one carrying adenine, joined through a pyrophosphate bridge, which is why the molecular formula carries two phosphorus atoms.
Identity is confirmed before we open a container. Purity is measured after. A purity result says how much of the lot is one substance; an identity result says which substance that is. A wrong molecule can measure high on purity, which is why the two are never the same test.
Every line has a method and a limit.
A lot that misses a single line is not released.

FOR PHYSICIAN USE ONLY · Rx ONLY
Dispensed pursuant to a valid prescription. As printed on the vial and the carton. No pharmacy name appears on the label — the pharmacy of record is disclosed when it dispenses, not in advance.
Storage is printed on the vial.
The condition on the label, the condition once in use, and the container.
Conditions
As labeledThe storage condition is printed on the vial and on the carton, and the stability summary is the data behind it. The in‑use condition applies from the moment the seal is broken.
Every container is quarantined until we confirm what it is. A supplier’s certificate is a claim, not a result. Nothing leaves quarantine on a claim.
This entry stands on one authority.
Your pharmacy of record dispenses it.
GradeBio does not dispense and never ships to a patient. Material is supplied only on a valid prescription for an individually identified patient, and your pharmacy of record dispenses it. You write the prescription. The pharmacy fills it. We supply the material and the paperwork that proves what it is. Read the rule this entry stands on.
On the research channel, this entry is supplied on the research channel, to verified research institutions, against a named principal investigator and an institutional authorization. It ships to your institutional address — never a residence, never a clinic. We supply no protocol and no guidance for its use.
