How to Reconstitute NAD+: A Beginner's Step-by-Step Guide

Built by medical professionals, gym rats, and experienced biohackers

Injectable NAD+ arrives as a freeze-dried powder that must be mixed with sterile water before use. That mixing process is called reconstitution. This guide walks you through each step, explains the math, and helps you avoid the most common beginner mistakes.

What Is NAD+ and Why Does It Come as a Powder?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of the body. Researchers study it for its roles in cellular energy production and DNA repair.

The injectable form comes as a lyophilized, or freeze-dried, powder because liquid NAD+ is unstable and breaks down quickly. Removing the water extends shelf life and keeps the compound stable during shipping. You add the water back yourself right before use.

Oral NAD+ precursors such as NMN or NR come in capsule form and need no mixing. The injectable research form is different and requires this preparation step.

What Supplies Do You Need?

Getting everything together before you start keeps the process clean and organized. You will need:

Your NAD+ vial (check the label for the milligram amount, commonly 100 mg, 500 mg, or higher)
Bacteriostatic water (labeled "for injection" or "bacteriostatic")
Alcohol swabs (70% isopropyl)
A mixing syringe, typically 3 mL to 5 mL
Smaller dosing syringes sized to your planned dose
A clean, flat surface

Do not use plain sterile water for multi-dose vials. Bacteriostatic water contains a small amount of benzyl alcohol that prevents bacterial growth, keeping the vial safe across multiple draws.

How Do You Mix NAD+ Step by Step?

Sterility is the most important part of this process. Work on a clean surface and avoid touching needle tips or vial stoppers with bare hands.

Wash your hands thoroughly with soap and water.
Wipe the stopper of your NAD+ vial and your bacteriostatic water vial with a fresh alcohol swab. Let them air dry a few seconds.
Draw your chosen volume of bacteriostatic water into the mixing syringe.
Insert the needle into the NAD+ vial at a slight angle and inject the water slowly. Aim the stream at the inside glass wall, not directly onto the powder. This gentle flow prevents foaming and degradation.
Remove the needle and swirl the vial gently in your palm until the powder fully dissolves and the liquid runs clear.
Do not shake. Shaking introduces air bubbles and can stress the compound.
If the liquid stays cloudy after a few minutes of gentle swirling, do not use it.
Label the vial immediately with the date mixed and the concentration you calculated.
Refrigerate right away.

How Do You Calculate Concentration?

This step matters because NAD+ doses are often measured in larger milligram amounts than many other research compounds. A small math error can produce a very different dose than intended.

The formula is simple: divide total milligrams by total milliliters added.

100 mg vial plus 2 mL water = 50 mg per mL
500 mg vial plus 10 mL water = 50 mg per mL
500 mg vial plus 5 mL water = 100 mg per mL

Choose a water volume that gives you a concentration easy to measure accurately with your syringe. A concentration that requires drawing a very small fraction of a milliliter increases your margin of error.

DoseVault has a built-in reconstitution calculator at DoseVault where you enter your vial size and water volume and it returns the exact concentration and dose volume instantly, with no manual math required.

How Long Does Reconstituted NAD+ Last?

Once mixed with bacteriostatic water, reconstituted NAD+ is generally considered stable for up to 30 days when refrigerated. Some researchers note that NAD+ may degrade faster than many other peptides and recommend smaller batch sizes or more frequent mixing.

Keep the vial in the back of the refrigerator where temperature stays most consistent. Avoid the door shelf, which experiences temperature swings. Never freeze a reconstituted vial.

Discard the vial if you notice any color change, cloudiness, or floating particles.

What Are the Most Common Mistakes Beginners Make?

These come up repeatedly in reconstitution discussions.

Using the wrong water. Plain sterile water is acceptable for single-use vials, but bacteriostatic water is the right choice when you plan to draw from the vial more than once.

Injecting water too fast. Spraying water directly onto the powder causes foaming. Slow and angled always works better.

Skipping the label. Write the date and concentration on the vial immediately after mixing. After a week in the fridge, you will not remember the details.

Shaking instead of swirling. Shaking stresses the compound and introduces bubbles. Swirl gently and patiently.

Not confirming the math. Double-check your concentration calculation before drawing your first dose. One decimal point in the wrong place changes everything.

FAQ

Can I use regular water instead of bacteriostatic water?
Plain sterile water works for single-use mixing, but bacteriostatic water is the standard choice when drawing from the vial more than once. The preservative it contains helps prevent contamination between uses.

Does reconstituted NAD+ need to stay cold the whole time?
Yes. Refrigerate the vial immediately after mixing. Leaving it at room temperature for extended periods can accelerate degradation.

What if the powder does not fully dissolve?
Swirl gently for a few minutes. If cloudiness remains, the vial may be compromised. Do not use a solution that will not clear.

Is there a way to verify my dose math without doing it by hand?
Yes. A reconstitution calculator removes the manual step entirely. Enter your vial size and water volume and it returns the exact volume to draw for your target dose.
