About NAD+
NAD+ is a coenzyme present in every cell, required for the reactions that turn food into usable energy and for the DNA repair enzymes that keep genomes intact. Its levels fall substantially with age, and that decline is one of the most consistently reproduced findings in ageing biology — which is why NAD+ has become a cornerstone of longevity protocols rather than a niche interest.
Injectable NAD+ exists for the same reason injectable glutathione does: the oral route is inefficient. Oral NAD+ is largely broken down before absorption, which is why most oral products supply precursors like NMN or NR instead and hope the body converts them. A 500mg vial supplies the molecule itself. It is one of two catalogue items with a 10 mL reconstitution allowance, because at 500mg a standard volume would be unusable.
Specifications
Evidence level: Early human studies · Direct NAD+ has small pilot studies; oral precursors such as nicotinamide riboside have larger trials.

How our batches are tested
Demand for peptides has grown quickly, and the factories that make them now run batches far more often than they used to. When batches were large and infrequent, we could test each one ourselves. At today’s pace that stopped being practical: independent testing is priced per sample, per compound, in US dollars.
So we share it. STRIATA is one of a group of companies across South Africa that buy from the same factory, and together we split the cost of independent lab testing. Each test is paid for once and shared by everyone who buys from that factory, which lets the testing keep pace with the batches.
That is why the client named on a certificate may be another company, and why the vial in a lab’s photo may carry another brand’s label: the report names whoever sent that sample in. We publish every certificate exactly as the lab issued it, unedited. If you have a question about a certificate, ask us on WhatsApp.

What it’s researched for
Research context, not medical advice. Everything we sell is supplied for research purposes.
Cellular energy
NAD+ is required for the reactions that generate ATP; the age-related decline in it is the clearest link between the molecule and how ageing feels.
DNA repair
The PARP enzymes that repair DNA damage consume NAD+ directly, which is one of the mechanisms behind the longevity interest.
Cognitive clarity
A substantial research interest in its own right — covered in a separate Learn article on NAD+ and brain health.
Healthy ageing
The sirtuins, the enzyme family most associated with longevity signalling, are NAD+-dependent. That dependency is why NAD+ anchors most longevity stacks.
What the research does not show
The limits of the evidence, stated as plainly as the findings.
- That raising NAD+ slows ageing in people.
Reconstitution and storage
NAD+ is the other 10 mL exception alongside glutathione: 500mg in the usual 3 mL would be impractically concentrated. Reconstituted with 10 mL of bacteriostatic water it gives 50mg/mL. The reconstitution calculator applies the higher limit automatically when you select it. Unopened vials are stable at room temperature in transit but belong in a fridge once they arrive, and out of a parked car in a Highveld summer.
