What is it?

Listed on peptide invoices as injectable NAD+. IV/IM NAD+ is not an approved general wellness medicine in the way it is marketed. Not sold as a peptide vial here.

Mechanism of action

Redox cofactor and sirtuin/PARP substrate.

Essential biochemistry; that does not validate unregulated injections.

What is it being studied for?

  • Infusion clinics (low-quality evidence), precursor trials

Investigational findings are not proven clinical benefits unless an authority has labelled that indication.

Evidence level

Overall human evidence grade: C · Limited or early human evidence

Human research

Oral precursors have more trial data than boutique NAD+ drips.

Preclinical research

Animal, cell and in-vitro findings are listed separately from human effects.

Foundational biochemistry.

Doses reported in published research

This section does not provide personalised medical dosing. Values are those reported in papers or protocols. Animal mg/kg doses are not converted to human doses.

Doses reported in human studies

Insufficient reliable evidence identified.

Preclinical / animal study dosing

Insufficient reliable evidence identified.

Pharmacokinetics

Reliable human pharmacokinetic data were not identified for this encyclopaedia entry, or are limited to product information for approved presentations.

Safety

Infusion reactions reported anecdotally; product quality varies.

Unknowns. Absence of a published harm signal is not evidence of safety.

Contraindications. Not a peptide-shop product.

Regulatory status

Not approved as a compounded anti-ageing injection in this model.

Educational for injectable NAD+. The shop sells oral NAD+ tablets and transdermal NAD+ patches — not NAD+ injections.
