1. Read the current label
Enter the total NAD+ amount printed on the vial and the total liquid volume for that same vial. Do not combine values from two products.
This NAD+ calculation guide connects a clearly labeled vial amount, liquid volume, target mass, mL, and U-100 markings. It does not select a dose, schedule, route, or product.
Illustrative arithmetic · not dosing guidance
Every row is arithmetic based on 5 mg in 2 mL, producing a concentration of 2.5 mg/mL. This is not a mixing instruction. The target values are mathematical examples. They are not common, prescribed, or recommended doses.
| Example target | Volume at 2.5 mg/mL | U-100 marking |
|---|---|---|
| 0.25 mg | 0.1 mL | 10 units |
| 0.5 mg | 0.2 mL | 20 units |
| 1 mg | 0.4 mL | 40 units |
These are mathematical examples only, not common or recommended NAD+ doses. Replace every value with instructions from a licensed professional and the current product label.
Three-step calculation
This page explains the calculation. The shared Peptide Calculator applies values you already have and never chooses a vial amount, liquid volume, target mass, or schedule.
Enter the total NAD+ amount printed on the vial and the total liquid volume for that same vial. Do not combine values from two products.
Use the CTA above to preselect NAD+, then replace every illustrative value with the vial, liquid, and target values from your qualified source.
Read concentration first, then mL, then the U-100 marking. Repeat the decimal and unit conversion independently before relying on the result.
Product-specific context
Nicotinamide adenine dinucleotide is included here because users search for it alongside longevity compounds, not because it is chemically a peptide. This navigation grouping does not imply equivalence.
A NAD+ dosage calculator can only convert values that are already known. It cannot verify identity, purity, sterility, formulation, route, clinical suitability, or whether a product is lawful or approved.
U-100 syringe units describe liquid volume: 100 units equals 1 mL. The mass of NAD+ represented by that volume changes with concentration, so a unit value from another vial or source must never be copied.
Transparent arithmetic
The name does not change the equations. Concentration links mass to volume; the U-100 conversion is applied last.
vial mg ÷ liquid mL = mg/mLtarget mg ÷ mg/mL = mLdose mL × 100 = unitsIf the target is entered in mcg, divide by 1,000 before using the dose-volume formula. The linked calculator does this conversion internally while keeping both mass units visible in the result.
Before accepting a result
Do not apply vial arithmetic to a pen, tablet, capsule, ampoule, nasal product, or fixed-dose device unless its official instructions explicitly require that calculation.
Take the total mass and liquid volume from the same NAD+ product. Do not combine values from different sellers, batches, or formulations.
Milligrams and micrograms describe mass; milliliters and U-100 markings describe volume. Verify the 1,000-fold mg-to-mcg conversion independently.
