Quickstart Overview

NAD+ (nicotinamide adenine dinucleotide) is a central redox coenzyme and the substrate for sirtuins and PARPs — enzymes governing DNA repair, metabolism and aging. Injectable NAD+ is studied for cellular energy, longevity and recovery as levels decline with age.

Units assume a U-100 insulin syringe (100 units = 1 mL). Inject VERY slowly — rapid NAD+ causes flushing, nausea and chest tightness.

Frequency: Daily or several×/week

Reconstitution Steps

  1. 1Allow the lyophilized vial and bacteriostatic water to reach room temperature (~15 min).
  2. 2Swab both vial stoppers with a fresh 70% isopropyl alcohol pad and let them dry.
  3. 3Draw 2.0 mL of bacteriostatic water into a mixing syringe.
  4. 4Insert at an angle and let the water run slowly down the glass wall — never directly onto the powder.
  5. 5Gently swirl (do not shake) until the solution is completely clear.
  6. 6Label with date and concentration (mg/mL) and refrigerate at 2–8 °C immediately.

Supplies Needed

Planning example for a 8-week protocol at approximately 100000 mcg per day.

Peptide (100 mg vials)
Estimate vials from total mass: 100000 mcg/day × 56 days.
Bacteriostatic Water
One 10–30 mL vial typically covers a full cycle.
Insulin Syringes (U-100)
One per administration (29–31 G, 0.3–0.5 mL).
Alcohol Swabs
Two per administration (vial + site).
Sharps Container
Required for safe disposal.

Storage Instructions

Lyophilized
−20 °C long term (18–24 months); stable at room temperature for short transit.

Freeze/Thaw
Avoid repeat freeze–thaw cycles after reconstitution.

Important Notes

  • Slow administration is essential — fast NAD+ is very uncomfortable (flushing, nausea).
  • Longevity evidence in humans is still early.

How This Works

NAD+ shuttles electrons in metabolism (glycolysis, the TCA cycle, oxidative phosphorylation) and is consumed by sirtuins (SIRT1-7) and PARPs during DNA repair and gene regulation. Cellular NAD+ falls with age and metabolic stress; restoring it is proposed to reactivate sirtuin-mediated maintenance pathways, improve mitochondrial function and support DNA repair. Injection bypasses the limited oral bioavailability of NAD+ itself.

Potential Benefits & Side Effects

Reported in research
  • Substrate for sirtuin and PARP maintenance pathways
  • Support for mitochondrial energy production
  • Studied for cellular energy, focus and recovery
  • Interest in DNA repair and longevity
Possible considerations
  • Flushing, nausea or chest tightness with fast injection (inject SLOWLY)
  • Injection-site discomfort
  • Transient cramping
  • Human longevity evidence is still preliminary

Lifestyle Factors

  • Adequate hydration and 7–9 h of sleep are standard controls in most research protocols.
  • Consistent dose timing improves the reliability of any self-tracked endpoints.
  • Maintain a clean, sterile workflow for every draw to avoid contamination.

Injection Technique

  1. 1Wash hands, then prep the vial top and the target site with separate alcohol swabs.
  2. 2Pinch a subcutaneous skin fold (abdomen, ~2 inches from the navel) and insert at 45–90°.
  3. 3Depress the plunger slowly over 3–5 seconds, hold 5 seconds, then withdraw.
  4. 4Rotate sites each administration and dispose of the syringe in a sharps container.
