Introduction
NAD+ (nicotinamide adenine dinucleotide) is a critical coenzyme in cellular metabolism, playing a central role in energy production and DNA repair. For researchers working with NAD+ vials, understanding proper reconstitution and dosing is essential. This guide covers the practical aspects of preparing and using NAD+ in research settings.
Understanding NAD+ Vials
NAD+ typically comes in lyophilized (powder) form in vials ranging from 250mg to 1g. The most common research vials contain 250-500mg of NAD+. The compound must be reconstituted with bacteriostatic water before use.
Reconstitution: The Basics
Choosing Your Dilution
The amount of bacteriostatic water you add determines the concentration of your solution:
250mg vial options:
- 2.5mL water = 100mg/mL (1mL = 100mg)
- 5mL water = 50mg/mL (1mL = 50mg)
- 10mL water = 25mg/mL (1mL = 25mg)
Recommendation: For most research purposes, a 5mL dilution (50mg/mL) provides a good balance of manageable injection volumes and precise dosing.
Weekly Regimen Guidelines
Starting Conservative
For those new to NAD+ research:
- Week 1-2: Start with 50-100mg twice weekly
- Week 3-4: Increase to 100-200mg twice weekly if tolerated well
- Maintenance: 100-250mg twice weekly
Common Research Protocols
- Conservative Protocol: 50mg 2x/week = 100mg/week
- Moderate Protocol: 100mg 2x/week = 200mg/week
- Intensive Protocol: 150-250mg 2x/week = 300-500mg/week
Administration Considerations
- Subcutaneous injection is the most common route
- Best absorbed when taken on an empty stomach
- Morning administration is generally preferred
- Some researchers report mild flushing or warmth at higher doses
Calculating Your Dose
Use the PeptIQ Reconstitution Calculator for precise measurements:
Example calculation:
- Vial: 250mg NAD+
- BAC water added: 5mL
- Concentration: 50mg/mL
- Desired dose: 100mg
- Volume to draw: 2mL (100mg ÷ 50mg/mL = 2mL)
Storage Guidelines
- Reconstituted NAD+ should be refrigerated at 2-8°C
- Use within 30 days of reconstitution
- Keep away from light to preserve potency
- Never freeze reconstituted solution
Safety Considerations
- Always use sterile technique for reconstitution
- Use new needles for each draw
- Start low and increase gradually
- Monitor for any adverse responses
- This information is for research purposes only
Conclusion
Proper reconstitution and dosing are foundational to NAD+ research. Start conservative with a 50-100mg twice-weekly protocol, properly mixed at 50mg/mL concentration for easy measurement. Always prioritize sterile technique and proper storage to maintain compound integrity.
