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 (illustrative examples only)
> Example only, not your vial. The figures below are worked examples for a labeled vial size and diluent volume. A different mass or water volume changes every unit count. Check your label and run the reconstitution calculator.
The amount of bacteriostatic water you add determines the concentration of your solution. The figures below are worked examples for a labeled 250 mg vial. They are not a universal mix, a product IFU, or a recommended protocol. Change the water volume and every milligram-per-mL and unit count moves.
Example 250 mg vial dilutions:
2.5 mL water → 100 mg/mL (1 mL = 100 mg)
5 mL water → 50 mg/mL (1 mL = 50 mg)
10 mL water → 25 mg/mL (1 mL = 25 mg)
Why 5 mL shows up in educational write-ups: that dilution makes 50–100 mg discussion figures land on readable syringe marks for many people. That is calculator readability, not a prescribed reconstitution.
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
Some researchers report mild flushing or warmth at higher doses
Calculating Your Dose
Use the PeptIQ Reconstitution Calculator for precise measurements:
Worked example (not a protocol):
Vial labeled: 250 mg NAD+
Example BAC water added: 5 mL
Resulting concentration: 50 mg/mL
Example target: 100 mg
Volume to draw: 2 mL (100 mg ÷ 50 mg/mL = 2 mL)
Those numbers only hold for that labeled mass and that diluent volume. They are arithmetic, not dosing advice.
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

Conclusion
Reconstitution math and the community ranges above are educational. A 50–100 mg twice-weekly discussion figure mixed at an example 50 mg/mL concentration is calculator arithmetic for readability, not a universal prescription. Always prioritize sterile technique, product-specific instructions when they exist, and clinician guidance over forum defaults.
No. PeptIQ publishes educational summaries and tracking tools. Talk with a licensed clinician about whether any therapy is appropriate for you.
Can I log what I read here in the PeptIQ app?
Yes. Use PeptIQ on iOS, Android, or the web to save notes, vials, and check-ins. Availability follows your App Store or Google Play region (including the US, Canada, and Australia).
Where can I find research-use peptide listings?
On guides that mention Blank Peptides SKUs (for example BPC-157, retatrutide, GHK-Cu, NAD+, tirzepatide, or semaglutide), the sidebar and exit popup link to research-use-only listings via /go/ruo. Those listings are not for human consumption. PeptIQ may earn a referral fee.
