NAD+ is a coenzyme rather than a peptide, but it is sold by the same vendors as a lyophilised powder and the arithmetic is identical. Vials are large, 100, 500 or 1,000 mg, and doses are in tens of milligrams, so the concentrations are far higher than anything else on this site. It is not an approved injectable medicine. Flushing, nausea and pain at the injection site are widely reported, and the pain tracks concentration, which is the one reason here to use more water than the draw alone would need.

The 500 mg vial, in detail

A 500 mg vial with 2 mL of bacteriostatic water is 250 mg/mL, so 50 mg is 0.2 mL, or 20 units, and the vial holds 10 doses of that size. It is the most common vial and the most common setup, which is why it is worth its own table.

NAD+ dosage per day

Commonly reported daily amounts sit at 50 to 100 mg, which from a 500 mg vial in 2 mL is 20 to 40 units. Reports generally describe starting at the low end, often 25 mg, and working up as tolerance to the flushing and the sting allows. The wider range the presets cover is 25 to 200 mg. There is no licensed daily dose; this is a description of what gets reported, not a recommendation.

NAD+ dosage per week

At the commonly reported 50 mg a day the weekly total is 350 mg, and at 100 mg a day it is 700 mg, so a 500 mg vial is roughly a week and a half at the low end and five days at the high end. Run three times a week instead and the same per-dose amounts come to 150 and 300 mg a week. The table gives the weekly total, the vial burn and the units for each pattern, all from a 500 mg vial in 2 mL (250 mg/mL).

NAD+ injection frequency

The two patterns that get reported are once daily and three times a week, usually in blocks of one to two weeks rather than continuously, with larger amounts spread over more injections rather than taken in one. Frequency is also where the site pain shows up: the same weekly total split into more, smaller, more dilute injections is the change people describe making when the sting is the problem. Nothing here is a schedule anyone has licensed, and how often is a clinical question, not an arithmetic one.

Why NAD+ numbers look wrong at first

Every other compound on this site is dosed in milligrams or micrograms out of a vial holding a few milligrams. NAD+ is dosed in tens of milligrams out of a vial holding hundreds, so the concentrations are enormous by comparison: 500 mg in 2 mL is 250 mg/mL, where a 10 mg peptide vial in 2 mL is 5 mg/mL, fifty times weaker. That is why a 50 mg dose of NAD+ is only 20 units while a 5 mg dose of something else can be 100. The draw is small because the solution is strong, not because the dose is.

It is also why the water volume is a genuine trade-off here rather than a convenience. More water lowers the concentration, which is what most people report helps with the sting, but it makes the draw bigger: 100 mg from a 500 mg vial is 40 units at 2 mL and 100 units at 5 mL. Past that you run out of syringe.

Live version: the NAD+ dosage calculator, which takes any vial, water volume and dose and gives cost per dose if you enter the vial price. To pick a water volume first, use the bacteriostatic water calculator.

Common questions

How many units is 100 mg of NAD+?
40 units on a U-100 syringe from a 500 mg vial reconstituted with 2 mL of bacteriostatic water, which is 250 mg/mL. From a 1,000 mg vial with 5 mL it is 50 units, and from a 500 mg vial with 5 mL it is 100 units, a full syringe.
What is a common NAD+ dose per day?
Reports cluster at 50 to 100 mg a day, which is 20 to 40 units from a 500 mg vial in 2 mL, with people often starting nearer 25 mg. There is no licensed dose; it is not an approved injectable medicine.
How much NAD+ per week?
At 50 mg daily, 350 mg a week, so a 500 mg vial lasts ten days. At 100 mg daily it is 700 mg a week and a 500 mg vial is five days. Three times a week at 100 mg is 300 mg a week.
How often is NAD+ injected?
Once daily and three times a week are the two patterns that get reported, usually in blocks of one to two weeks rather than continuously. Splitting a weekly total into more, smaller, more dilute injections is the change people describe making when the injection-site sting is the problem.
How much bacteriostatic water for a 500 mg NAD+ vial?
2 mL is the usual choice and gives 250 mg/mL, so 50 mg is 20 units and 100 mg is 40 units. More water lowers the concentration, which is what most people report helps with the sting, at the cost of a bigger draw: at 5 mL, 100 mg is a full 100 units.

Tools

Before you use these numbers This is a unit-conversion tool. It turns a vial strength and a water volume into a concentration, a draw volume and a syringe mark. It does not tell you what to take, whether to take it, or whether a compound is safe for you. Most compounds listed are sold for laboratory research and are not approved for human use. Nothing here is medical advice. Dosing decisions belong with a licensed clinician who knows your history. Always check the strength printed on your own vial rather than trusting a preset.
