NAD+ is a coenzyme every cell uses to convert food into energy, and people inject it to push back against the natural age-related drop in NAD+ levels. Most users report it for energy, mental clarity, and recovery; researchers also study it for DNA-repair and metabolic-aging pathways. Human studies confirm injections raise blood NAD+ levels meaningfully, though long-term outcome data is still developing. This page covers reconstitution math and typical daily-or-cycle logging cadence.

How the four NAD+ calculators connect

This tool turns the three numbers on your NAD+ vial into the only number that matters at injection time: how many units to draw on a U-100 insulin syringe. The math is one formula — concentration in mg per mL equals the milligrams of peptide in the vial divided by the milliliters of bacteriostatic water you add — and every other answer falls out of that.

In the worked example below, a 100 mg vial of NAD+ reconstituted with 5 mL of BAC water produces a concentration of 20 mg/mL. To draw the example dose of 50 mg from that vial you pull 2.50 mL — about 250 units on a standard insulin syringe. Change any input and the rest updates instantly so you can pre-plan a vial before you ever touch a needle.

Vial size, diluent volume, and dose are the three inputs that genuinely change the answer. Doses-per-vial is a derived output — it's the vial mg divided by the dose mg, rounded down. The most common edge case is a tiny dose: at very high concentration, a 0.1 mL draw is only a few units on the syringe, which is hard to read accurately. If your unit count drops below five, consider reconstituting the next vial with more BAC water so each dose covers a larger volume.

Use this calculator any time you open a fresh vial, switch BAC water volume, or step a titration dose up. Each new vial gets its own concentration and its own unit count — the previous vial's numbers do not carry over, and that is the single most common reconstitution mistake.

What the NAD+ calculators cover

NAD+ — nicotinamide adenine dinucleotide — is technically a coenzyme rather than a peptide, but it is commonly supplied and tracked in the same lyophilized-vial workflow as the peptides on this site. Vial sizes are typically much larger than peptide vials, often 100 mg or 500 mg.

Cadence varies widely between users. Weekly, twice-weekly, and intensive-loading protocols all appear in personal logs. The flexible cadence makes a structured dose log even more useful for retrospectively understanding what was actually done.

Nicotinamide adenine dinucleotide (NAD+) is, from a chemical standpoint, not a peptide. It contains no amino acids and no peptide bonds. Its molecular structure is that of a dinucleotide, which is composed of two nucleotide units joined together through their phosphate groups. One of these nucleotides contains an adenine base, while the other contains nicotinamide. Despite its non-peptide identity, NAD+ is frequently included on platforms dedicated to peptide tracking because it shares an identical supply and self-administration workflow. It is commonly supplied as a lyophilized powder in vials, requiring reconstitution with a diluent prior to use, making it a logical candidate for inclusion in tracking and calculation tools.

How NAD+ is studied

NAD+ is a coenzyme involved in cellular energy metabolism and is studied in a wide range of contexts. As with every other entry on this site, mechanistic and clinical specifics are out of scope for a calculator page.

From a biochemical perspective, NAD+ functions as a critical coenzyme in a vast number of cellular processes. Its primary role is as an electron carrier in oxidation-reduction (redox) reactions, which are fundamental to metabolism and cellular energy production. During these reactions, the NAD+ molecule can exist in two forms: its oxidized state (NAD+) and its reduced state (NADH). By cycling between these two forms, it facilitates the transfer of electrons from one molecule to another. Additionally, NAD+ serves as a substrate for several important classes of enzymes, including sirtuins and poly (ADP-ribose) polymerases (PARPs). These enzymes consume NAD+ to carry out their functions, which are subjects of intense study related to cellular maintenance and signaling.

How people log NAD+

Cadence and dose magnitude vary so much between users that recording the cadence explicitly in each log entry is essential. Without it, retrospective trend analysis is unreliable.

Many NAD+ users alternate between intensive loading periods and lower-frequency maintenance. Recording the transition between phases — the same way it is done for Melanotan-2 — keeps the timeline auditable.

Research protocols for subcutaneous NAD+ administration sometimes describe distinct phases for loading and maintenance. A loading phase might involve a higher frequency of administration, such as daily doses over a period of 5 to 14 days. The objective of such a phase in a research context is to rapidly alter the systemic concentration of the molecule. Following this initial period, the protocol might shift to a maintenance phase, characterized by a reduced frequency, such as a single administration per week. This two-phase structure requires diligent scheduling and tracking to accurately document the shift in dose timing and to monitor observations across both distinct periods of the protocol.

Common NAD+ mistakes to avoid

  • Drifting from a planned cadence and not recording the change in real time.
  • Trying to fit a 50 mg dose into a single insulin-syringe draw without re-running the math.
  • Reusing a unit count from a previous vial without re-checking diluent volume.
  • Letting reconstituted NAD+ warm to room temperature on travel days.
  • Not writing the reconstitution date on the vial.
  • Failing to distinguish between NAD+ and its precursors, such as NMN and NR, when recording data, leading to an inaccurate log of which molecule is being observed.
  • Miscalculating the dose volume and not planning for the need for multiple insulin syringes or a single larger syringe to administer the full calculated amount.
  • Confusing the dosing frequency and amount from a loading phase with that of a long-term maintenance phase when scheduling and documenting protocol adherence.

Frequently asked questions about NAD+

Is NAD+ a peptide?
Technically no — it is a coenzyme, not a peptide. It is included on this site because it is tracked using the same lyophilized-vial workflow as the peptides, and the same calculators apply.
How is NAD+ reconstituted?
Add a measured volume of bacteriostatic water through the rubber stopper and swirl gently until the powder fully dissolves. A 100 mg vial with 5 mL of BAC water gives a concentration of 20 mg per mL.
How many units of NAD+ are in 50 mg?
On a 100 mg vial reconstituted with 5 mL of bacteriostatic water (20 mg per mL), 50 mg is exactly 2.5 mL or 250 units. That is too large for a single 1 mL insulin syringe and is typically split or delivered with a larger syringe.
Is NAD+ dosed weekly?
Cadence varies enormously between users — weekly, twice-weekly, and intensive loading protocols all appear in personal logs. Recording the cadence explicitly in each entry is essential.
How long does a 100 mg NAD+ vial last?
At a 50 mg weekly dose, a 100 mg vial provides 2 doses — about 2 weeks of supply. The vial duration calculator runs the math for any combination of vial size, dose, and frequency.
Does NAD+ need to be refrigerated?
Lyophilized powder is typically stored refrigerated, and the reconstituted vial is kept refrigerated and used within several weeks.
What is the difference between NAD+, NMN, and NR?
NAD+ is the final, active coenzyme used by cells. NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are precursor molecules. In the body's natural pathways, NR is converted to NMN, and NMN is then converted to NAD+. Protocols that involve the administration of NAD+ directly are designed to bypass these conversion steps. When you log your activities, it is critical to specify which of these three distinct molecules you are tracking.
Why are the doses for IV infusion and subcutaneous injection so different?
The two routes of administration are studied with different objectives and kinetics. IV infusions deliver a very large dose (e.g., 500 mg) directly into the bloodstream over a period of hours. Subcutaneous injections involve a much smaller dose (e.g., 50 mg) that is absorbed more slowly from the tissue beneath the skin. Due to this order-of-magnitude difference in dosage and delivery method, it is essential that your tracking log clearly records both the dose and the specific route of administration.
Should I use reconstituted lyophilized powder or a pre-mixed solution?
NAD+ can be supplied in two primary forms. The first is as a lyophilized (freeze-dried) powder, which must be reconstituted with a sterile diluent, such as bacteriostatic water, before it can be used; this process should be carefully documented. The second form is a pre-mixed, chemically stabilized solution that does not require reconstitution. Either form can be studied, but your personal log should accurately document the specific product form you are using, as storage and handling may differ.
Why is the injection volume for subcutaneous NAD+ often so large?
The large volume is a direct result of the molecule's properties and the resulting concentration after reconstitution. For example, dissolving a 100 mg vial with 5 mL of diluent creates a 20 mg/mL solution. To administer a 50 mg illustrative dose from such a vial, a volume of 2.5 mL is required. This is significantly larger than the volume for many peptides and exceeds the capacity of a standard 1 mL insulin syringe, necessitating careful planning for dose administration.
