Quickstart Highlights
NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme involved in cellular energy production, mitochondrial function, and DNA repair processes. It plays a key role in metabolic pathways and overall cellular maintenance.
While clinical applications have traditionally focused on high-dose intravenous (IV) administration, lower-dose subcutaneous protocols are increasingly explored in research settings as a more practical and consistent approach.
This protocol outlines a once-daily subcutaneous dosing strategy with gradual titration, designed to support tolerability and consistency in controlled environments.
- Reconstitution: Add 3.0 mL bacteriostatic water → 166.7 mg/mL concentration
- Typical Range: 50–100 mg daily (gradual increase recommended)
- Measurement Guide:
- 1 unit (U-100 syringe) = 0.01 mL ≈ 1.67 mg
- Administration: Subcutaneous injection, once daily
- Storage:
- Lyophilized: Store frozen
- Reconstituted: Refrigerate (2–8°C) and use within 14 days
Dosing & Reconstitution Guide
Educational guide for reconstitution and daily dosing
Standard / Gradual Titration Approach (3 mL = 166.7 mg/mL)
| Week | Daily Dose (mg) | Units (U-100) | Volume (mL) |
|---|---|---|---|
| Week 1 | 50 mg | 30 units | 0.30 mL |
| Week 2 | 75 mg | 45 units | 0.45 mL |
| Weeks 3–8 | 100 mg | 60 units | 0.60 mL |
| Weeks 9–12 | 100 mg | 60 units | 0.60 mL |
| Weeks 13–16 | 100 mg | 60 units | 0.60 mL |
Frequency:
NAD+ is typically administered once daily via subcutaneous injection. This gradual titration protocol begins with a lower starting dose (50 mg) to assess individual tolerance, then increases incrementally to reach a maintenance range of 75–100 mg per day.
Using a 3.0 mL reconstitution volume allows for practical injection volumes and accurate measurement using a standard U-100 insulin syringe. Maintaining a consistent daily schedule is recommended to support stable levels throughout the protocol duration.
Reconstitution Steps
- Draw 2.0 mL bacteriostatic water using a sterile syringe
- Inject slowly into the vial (avoid direct powder impact)
- Gently swirl until dissolved (do not shake)
- Store refrigerated at 2–8°C
- Use within 4 weeks

Supplies Needed
The following estimates are based on an 8–16 week daily protocol with gradual dose titration as outlined above.
Peptide Vials (NAD+, 500 mg each)
- 8 weeks: Approximately 11 vials (total ~5,075 mg used)
- 12 weeks: Approximately 16 vials (total ~7,875 mg used)
- 16 weeks: Approximately 22 vials (total ~10,675 mg used)
Insulin Syringes (U-100, 1 mL)
- Weekly usage: 7 syringes (one per day)
- 8 weeks: 56 syringes
- 12 weeks: 84 syringes
- 16 weeks: 112 syringes
Bacteriostatic Water (10 mL bottles)
Each vial requires 3.0 mL for proper reconstitution.
- 8 weeks (11 vials): 33 mL total → 4 × 10 mL bottles
- 12 weeks (16 vials): 48 mL total → 5 × 10 mL bottles
- 16 weeks (22 vials): 66 mL total → 7 × 10 mL bottles
Alcohol Swabs
Use two swabs per day — one for the vial stopper and one for the injection site.
- Weekly usage: 14 swabs
- 8 weeks: 112 swabs → recommended 2 × 100-count boxes
- 12 weeks: 168 swabs → recommended 2 × 100-count boxes
- 16 weeks: 224 swabs → recommended 3 × 100-count boxes
Protocol Overview
- Goal: Support cellular energy pathways, mitochondrial activity, and metabolic function
- Duration: 8–16 weeks
- Dosing Strategy: Gradual titration to improve tolerance
- Frequency: Once daily
- Starting Dose: 50 mg per day
- Maintenance Range: 75–100 mg daily depending on response
Dosing Protocol
- Start with a low daily dose (100 mcg) during the initial phase
- Gradually increase to 150 mcg, then 200 mcg daily as needed
- Frequency: Once daily
- Administration: Subcutaneous injection
- Maintain consistent timing each day
- Typical protocol duration: 8–12 weeks
- Rotate injection sites regularly
Storage Instructions
Proper storage is essential to maintain peptide stability and integrity.
- Lyophilized (Unmixed): Store in a freezer at approximately −20°C (−4°F) for long-term preservation. If freezing is not available, refrigeration (2–8°C) is acceptable for shorter durations. Keep in a dry, dark environment away from moisture.
- After Reconstitution: Store the solution in a refrigerator at 2–8°C (35.6–46.4°F) at all times. Do not freeze once mixed.
- Shelf Life: Use within 28 days after reconstitution for optimal stability and reliability. Discard any remaining solution after this period.
Important Notes
Key considerations for consistency, handling, and research accuracy.
- Always use a new, sterile insulin syringe for each administration; do not reuse needles
- Follow proper aseptic technique: clean both the vial stopper and injection site with separate alcohol swabs and allow to dry fully
- Rotate injection sites (abdomen, thighs, upper arms) to reduce irritation and avoid tissue buildup
- Administer injections slowly and steadily, allowing a few seconds before withdrawing the needle
- Keep a record of dosing, timing, and injection sites to maintain consistency throughout the protocol
- Do not use the solution if it appears cloudy, discolored, or contains visible particles
- Store and handle peptides according to recommended conditions to preserve stability
How This Works
NAD+ functions as a key coenzyme in redox reactions and ATP production, playing an essential role in:
- Cellular energy metabolism
- Mitochondrial activity
- DNA repair pathways
- Cellular resilience and recovery
Declining NAD+ levels over time have been associated with reduced cellular efficiency, which is why it remains a focus in metabolic and longevity-related research.
Potential Benefits & Considerations
Potential Benefits
- Supports energy metabolism and ATP production
- May enhance mitochondrial function
- Contributes to cellular repair processes
- May support cognitive and metabolic performance
Potential Considerations
- Gradual dosing is recommended to minimize side effects
- Some individuals may experience mild fatigue, restlessness, or headaches
- Injection site irritation may occur
- Response can vary depending on dose and individual sensitivity
Lifestyle Factors
- Follow a balanced diet to support metabolic and endocrine pathways
- Maintain proper hydration for optimal physiological function
- Prioritize sleep and recovery to support hormonal balance
- Engage in regular physical activity to complement metabolic research models
- Manage stress levels, as stress can impact hormone signaling
- Avoid excessive processed foods when focusing on metabolic studies
Injection Technique
General guidance for subcutaneous administration based on established clinical practices.
Preparation
- Wash hands thoroughly using soap and water before handling supplies
- Clean the vial stopper with an alcohol swab and allow it to air dry
- Choose an injection site such as the abdomen (at least 2 inches from the navel), outer thigh, or back of the upper arm
- Clean the selected area with an alcohol swab and allow the skin to fully dry before injecting
Needle Selection
- Use a fine, short insulin syringe (28–31 gauge) for comfort and precision
- A needle length of 5/16 to 1/2 inch (8–12 mm) is generally suitable for subcutaneous injections
- Standard U-100 insulin syringes (1 mL) are appropriate for the typical injection volumes used in this protocol
Injection Procedure
- Gently pinch a fold of skin between your fingers to target subcutaneous tissue
- Insert the needle at approximately a 45° angle into the pinched skin
- (For very short needles, a 90° angle may be used if appropriate)
- Do not aspirate when performing subcutaneous injections
- Inject the solution slowly and steadily over 5–10 seconds to minimize discomfort
- After completing the injection, wait a few seconds before removing the needle at the same angle
- Apply light pressure with a clean swab or bandage if needed — avoid rubbing the area
- Dispose of the used syringe immediately in a proper sharps container
Site Rotation
- Rotate injection sites regularly to help prevent irritation, soreness, or tissue buildup
- Alternate between different areas (left/right abdomen or different quadrants) when injecting daily
- The abdomen is commonly preferred due to its consistent fat layer and lower sensitivity
- The outer thigh and upper arm can also be used as alternative sites
Volume Considerations
- Typical injection volumes range from 0.30 mL to 0.60 mL per dose
- Subcutaneous tissue can generally accommodate up to 1.5 mL per injection comfortably
- For higher doses, splitting the dose into two separate injection sites may improve comfort and absorption
