How much bacteriostatic water for a 100 mg NAD+ vial?

The amount of water does not change how much NAD+ is in the vial; it sets the concentration. With 1 mL a 100 mg vial is 100 mg/mL, with 2 mL it is 50 mg/mL and with 3 mL it is 33.333 mg/mL. More water makes each unit weaker, so a given amount takes more units to draw.

How many mcg are in one unit of a 100 mg NAD+ vial?

With 2 mL of water, one unit on a U-100 syringe holds 500 mcg (50,000 mcg per mL divided by 100). The table above gives the figure for other vial sizes and volumes.

Is this a NAD+ dosage calculator?

It converts between amounts, volumes and syringe units for NAD+; it does not suggest how much to use. The NAD+ guide lists the doses used in published studies, with their sources.

What size are NAD+ vials?

Across 29 listings in our directory, the most common sizes are 100 mg, 25 mg. Sizes and prices by store are on the NAD+ price page.

How many units are in 1 mL on an insulin syringe?

A U-100 insulin syringe holds 100 units per mL, so 1 unit is 0.01 mL.

NAD+ dosage calculator

Pick a NAD+ vial size, enter the bacteriostatic water added and, if you want, an amount per draw. The calculator gives the concentration and how many units that is on a U-100 insulin syringe. It does arithmetic only and does not suggest an amount.

U-100 syringes · 100 units = 1 mL · 1 mg = 1,000 mcg

Concentration

50 mg/mL

500 mcg per unit on a U-100 syringe · 5,000 mcg per 0.1 mL

Enter an amount per draw to see how many units it is and how many draws the vial holds.

Worked example

A 100 mg NAD+ vial with 2 mL of bacteriostatic water is 50 mg/mL (50,000 mcg/mL). One unit on a U-100 syringe is 0.01 mL, so each unit holds 500 mcg. To find how many units an amount is, divide the amount in mcg by 500.
