NAD+ (1000 mg Vial) Dosage Protocol

Dosing & Reconstitution Overview

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, where it sits at the centre of redox chemistry and energy metabolism. The figures below are compiled strictly for laboratory and educational reference — they describe how the compound has been handled and dosed in the published and compounding literature, not a recommendation for use in humans or animals.

For a 1000 mg vial, adding 3.0 mL of bacteriostatic water yields a concentration of 333.3 mg/mL. At that concentration, each 0.10 mL drawn on a U-100 insulin syringe equals 10 units and delivers roughly 33 mg of material. The titration steps below are expressed directly in units to keep the bench arithmetic straightforward.

Standard (Gradual) Titration Schedule

NAD+ is unusual among injectable research compounds in that it is modelled on a daily rather than weekly cadence. The gradual schedule opens at a low test dose, climbs by a small fixed increment over the first fortnight, then settles into a steady maintenance level. The slow ramp is used to limit the flushing, anxiety and sleep-disruption signals that have been associated with rapid escalation.

Reconstitution Steps

1. Let the sealed lyophilized vial reach room temperature, then wipe the stopper and the bacteriostatic water vial with an alcohol swab.
2. Draw 3.0 mL of bacteriostatic water with a sterile syringe and inject it slowly down the inside wall of the vial — never directly onto the powder pellet.
3. Swirl or roll gently until the powder is fully dissolved. Do not shake; vigorous agitation can damage the material.
4. The solution should be clear and colourless. Discard it if it appears cloudy or discoloured.
5. Label the vial with the concentration (333.3 mg/mL) and the reconstitution date, then refrigerate at 2–8 °C, protected from light.
6. Use within 14 days, inspect visually before each draw, and use a fresh sterile syringe every time.

Dosing Notes by Phase

Because the standard model already runs at a conservative daily ceiling, there is no separate aggressive titration arm in the documented protocols; the variation lies in how quickly the maintenance level is reached and whether the dose is ever pushed into the supervised therapeutic band.

Supplies Needed

• NAD+ vials (1000 mg): ~6 vials for an 8-week run; ~8 vials for a 12-week run; ~11 vials for a 16-week run to the 100 mg plateau.
• Insulin syringes (U-100, 1 mL): ~56 for 8 weeks, ~84 for 12 weeks, ~112 for 16 weeks — one fresh syringe per daily draw.
• Bacteriostatic water (10 mL): two bottles for 8 weeks, three for 12 weeks, four for 16 weeks.
• Alcohol swabs: two to three 100-count boxes across an 8–16 week schedule.

Protocol Overview

• Research goal: model cellular NAD+ repletion and its effects on energy metabolism and mitochondrial function.
• Schedule: once-daily subcutaneous administration in the documented model.
• Dose band: 50–100 mg daily standard; 200–300 mg only in supervised therapeutic study.
• Fill: 1000 mg lyophilized, reconstituted to 333.3 mg/mL with 3 mL diluent.
• Storage: −20 °C or below dry; 2–8 °C once reconstituted, used within 14 days.

Dosing Protocol Notes

• Open at 50 mg daily for Week 1 to gauge individual tolerance before climbing.
• Escalate by roughly 25 mg per week only while the prior step is well tolerated.
• Hold the 100 mg maintenance level through Week 16 in the standard model.
• Escalating too quickly has been linked to insomnia, anxiety or fatigue; slow the ramp if those appear.
• Daily doses beyond 200–300 mg are documented only under direct supervision, not in the self-directed model.

Storage Instructions

Keep sealed lyophilized vials at −20 °C (−4 °F) or below, protected from light; storage near −80 °C is preferred for multi-year stability. The powder is hygroscopic, so minimise moisture exposure when handling. Once reconstituted, refrigerate at 2–8 °C (35.6–46.4 °F) and use within about 14 days. Avoid repeated freeze-thaw cycles, and let refrigerated solution warm slightly before drawing.

Important Handling Notes

• Use a sterile syringe for every draw and never re-enter the vial with a used needle.
• Keep the reconstituted solution out of light and return it to refrigeration promptly between draws.
• Split volumes above roughly 150 mg across two sites to stay within comfortable subcutaneous limits.
• Document each draw — date, volume, remaining material — for reproducibility.

How NAD+ Works

NAD+ is a coenzyme central to redox reactions and energy metabolism, cycling between its oxidised (NAD+) and reduced (NADH) forms to shuttle electrons through glycolysis, the TCA cycle and oxidative phosphorylation. Beyond ATP production, it serves as a substrate for enzymes involved in DNA repair, mitochondrial biogenesis and cellular signalling, including the sirtuins and the PARP family. Cellular NAD+ pools tend to decline with age, a shift that has been linked in the literature to reduced mitochondrial function and diminished cellular resilience, which is the rationale behind repletion research.

Reported Benefits & Side Effects

Benefits reported in studies

• Potential support for cellular energy production and mitochondrial function.
• Case reports and pilot studies suggest cognitive and metabolic signals in the 100–300 mg/day range.
• High-dose IV protocols (500–1500 mg daily for ~10 days) have reported reduced cravings and improved mood in open-label substance-use work.
• No severe adverse events have been reported in published NAD+/NADH trials.

Side effects reported

• Dose-dependent insomnia, anxiety or fatigue, mostly tied to rapid escalation.
• Mild injection-site reactions — redness, itching or soreness.
• Transient headache or flushing.
• Effects generally resolve with slower titration and consistent site rotation.

Supporting Lifestyle Factors (Research Context)

• Diets supplying NAD+ precursors — niacin (vitamin B3) and tryptophan — alongside other B-vitamins and magnesium.
• Regular physical activity, which upregulates endogenous NAD+ biosynthesis.
• Seven to nine hours of nightly sleep as a standard study control.
• Stress management, since chronic stress depletes NAD+ pools via PARP activation.
• Moderating or eliminating alcohol intake during repletion protocols.

Injection Technique (Reference Only)

• Use a 28–31 gauge insulin syringe, 8–12 mm (5/16 to 1/2 inch) length, appropriate for the 0.15–0.30 mL volumes here.
• Pinch a skin fold, insert subcutaneously at roughly 45°, and inject slowly over 5–10 seconds without aspirating.
• Wait a few seconds before withdrawing, then apply light pressure with a swab rather than rubbing.
• Rotate daily between the abdomen (≥2 inches from the navel), outer thighs and back of the upper arms to prevent lipohypertrophy; subcutaneous tissue absorbs up to ~1.5 mL per injection.
