Your protocol

How NAD+ Injection is prescribed.

Who it's for
  • Adults who want a higher-dose NAD+ vial
  • Patients already comfortable with NAD+ injections

Your physician decides whether NAD+ Injection is appropriate for you after reviewing your intake and labs.

Directions & duration

Inject 0.83 mL (83 units) subcutaneously three times per week.

Cycle. Ongoing at your physician's direction.
Directions shown are the pharmacy's standard for this preparation. Your prescription label is the final word.
What's included
  • Licensed physician review of your intake, history, and labs
  • Medication compounded to your prescription by a PCAB-accredited, FDA-registered pharmacy
  • Every batch independently tested before release
  • Sterile syringes and alcohol prep pads for injectables
  • Tracked delivery to your door, refills on schedule
  • Message your physician anytime; dose changes without an appointment
Storage & handling
  • Store refrigerated (36–46°F / 2–8°C) at all times, including before first use.

The science

How NAD+ Injection works, and what the research shows.

How it works

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme at the center of cellular energy metabolism — required for converting food to ATP, and consumed by sirtuins and PARP enzymes involved in DNA repair and cellular stress responses.

NAD+ levels decline substantially with age; injection delivers the coenzyme directly rather than relying on oral precursors.

Clinical evidence
  • Human studies show oral NAD+ precursors (nicotinamide riboside, NMN) reliably raise blood NAD+ levels, and small pharmacokinetic studies have characterized intravenous NAD+ administration.

  • Direct clinical-outcome trials of injectable NAD+ remain limited — most of the aging and metabolism evidence comes from preclinical work and precursor studies, so treatment is physician-directed and investigational.
