NAD+ Dosage and Protocol Guide
This NAD+ page is really about picking the rhythm that feels easiest to keep up with: twice weekly or three times weekly. Both versions start low, step up in week 2, and settle into maintenance in week 3, but the per-injection amount and spacing feel different. This guide leads with that schedule choice first, then covers spacing, measurement, and how to keep the plan organized.

For a quick scan, this table summarizes the NAD+ injection frameworks provided for twice-weekly and three-times-weekly use.
| Route | Typical Range | Frequency | Duration | Common Research Context |
|---|---|---|---|---|
| Injectable / 2 times weekly | 20 mg to 120 mg per injection | 2 injections weekly | Week 1 entry, week 2 step-up, week 3+ maintenance | Builds from 40 mg weekly to 80 mg weekly, then 240 mg weekly at maintenance. |
| Injectable / 3 times weekly | 20 mg to 80 mg per injection | 3 injections weekly | Week 1 entry, week 2 step-up, week 3+ maintenance | Builds from 60 mg weekly to 120 mg weekly, then 240 mg weekly at maintenance. |
| Scheduling note | Keep the per-injection amount matched to the chosen option | Use evenly spaced injection days | Applies across all weeks | For the 3-times-weekly option, an every-other-day rhythm such as Monday, Wednesday, Friday is a clean example. Avoid back-to-back injection days. |
What Is the Typical NAD+ Dosage?
The core NAD+ schedule here is not built around a long titration ladder. Instead, it uses a short two-step ramp before settling into a recurring maintenance pattern in week 3 and beyond.
The main decision is whether the maintenance phase is easier to run as 120 mg twice weekly or 80 mg three times weekly. Those schedules reach the same 240 mg weekly total, but the per-injection amount and calendar structure are different.
That makes protocol design more about repeatability than complexity. A schedule is usually easier to follow when the injection days are predictable and the measured draw volume stays tied to a single concentration.
Because the source schedule already pairs milligrams with milliliters, the most useful planning lens is to keep the written mg target and the measured mL target aligned from week to week.
| Framework | Commonly Discussed Range | How It Is Usually Framed |
|---|---|---|
| Twice-weekly entry framework | 20 mg per injection in week 1, then 40 mg per injection in week 2 | Used when the goal is a simple 2-day weekly rhythm before transitioning into a higher maintenance amount. |
| Twice-weekly maintenance framework | 120 mg per injection, 2 times weekly | Keeps the weekly total concentrated into two larger injections once the opening weeks are complete. |
| Three-times-weekly entry framework | 20 mg per injection in week 1, then 40 mg per injection in week 2 | Uses the same stepped opening pattern but spreads the week across three injection days instead of two. |
| Three-times-weekly maintenance framework | 80 mg per injection, 3 times weekly | Reaches the same 240 mg weekly maintenance total while using smaller per-injection amounts. |
NAD+ Dosage by Administration Method
Twice-Weekly NAD+ Dosage
In the twice-weekly option, the schedule starts at 20 mg per injection in week 1, moves to 40 mg per injection in week 2, and then settles at 120 mg per injection from week 3 forward.
This format is useful when the goal is to keep the week simple with only two injection days while still arriving at the full maintenance weekly total.
Three-Times-Weekly NAD+ Dosage
In the three-times-weekly option, the first two weeks still step from 20 mg per injection to 40 mg per injection, but the maintenance phase uses 80 mg per injection three times per week instead of 120 mg twice per week.
That gives a smaller per-injection amount while preserving the same 240 mg weekly maintenance total. Spacing matters more here, so it helps to distribute the injections across non-consecutive days.
NAD+ Protocol Structure
Week 1 Entry Phase
Week 1 is the low-entry block. The schedule begins at 0.1 mL, which corresponds to 20 mg per injection in the source framework.
The practical objective is to establish the injection rhythm and confirm that the written dose matches the measured volume before moving up.
Week 2 Build Phase
Week 2 increases to 0.2 mL, or 40 mg per injection. This keeps the progression simple and preserves the same measurement logic established in week 1.
At this stage, the main planning question is not whether to add more complexity, but which ongoing weekly cadence will be easier to maintain once the week-3 schedule starts.
Week 3 and Beyond
From week 3 onward, the source schedule branches into two maintenance options: 0.6 mL twice weekly or 0.4 mL three times weekly.
Both options arrive at the same 240 mg total per week. The choice is therefore about calendar structure and per-injection size rather than about chasing a different weekly total.
| Schedule Option | Week 1 | Week 2 | Week 3+ | Planning Note |
|---|---|---|---|---|
| 2 times weekly | 0.1 mL (20 mg) per injection | 0.2 mL (40 mg) per injection | 0.6 mL (120 mg) per injection | Best framed as a simple 2-day weekly structure that reaches 240 mg total per week in maintenance. |
| 3 times weekly | 0.1 mL (20 mg) per injection | 0.2 mL (40 mg) per injection | 0.4 mL (80 mg) per injection | Spreads the same 240 mg maintenance weekly total across three smaller injections. |
| Spacing | Leave room between injection days | Keep the same general weekly rhythm | Avoid back-to-back days | A Monday, Wednesday, Friday pattern is a clean example for the 3-times-weekly option, but similar spacing works too. |
How Often Is NAD+ Typically Used?
NAD+ is framed here as either a 2-times-weekly or 3-times-weekly injectable schedule. The practical issue is not simply how often it is used, but how evenly the injection days are spread across the week.
For the 3-times-weekly option, an every-other-day style rhythm is the cleanest way to think about it. A Monday, Wednesday, Friday example works well because it preserves recovery time between injections without forcing exact calendar rigidity.
Some variation is fine as long as the schedule does not collapse into back-to-back injection days. Consistent spacing usually matters more than finding one perfect set of weekdays.
Example NAD+ Protocol
This is an educational rendering of the supplied NAD+ schedule. It keeps the same dosing pattern while presenting the plan in the site's standard protocol format.
| Option | Week 1 | Week 2 | Week 3+ | Notes |
|---|---|---|---|---|
| Twice weekly | 0.1 mL (20 mg) per injection | 0.2 mL (40 mg) per injection | 0.6 mL (120 mg) per injection | Weekly total progresses from 40 mg to 80 mg to 240 mg. |
| Three times weekly | 0.1 mL (20 mg) per injection | 0.2 mL (40 mg) per injection | 0.4 mL (80 mg) per injection | Weekly total progresses from 60 mg to 120 mg to 240 mg. |
| Three-times-weekly spacing example | Choose non-consecutive days | Keep the same spacing pattern | Continue with evenly distributed days | Monday, Wednesday, Friday is one straightforward example. |
How to Measure and Plan NAD+ Dosing
The supplied schedule already implies a fixed concentration because 0.1 mL corresponds to 20 mg. That works out to 200 mg per mL, which is why 0.2 mL maps to 40 mg, 0.4 mL maps to 80 mg, and 0.6 mL maps to 120 mg.
That relationship only stays true if the vial concentration stays the same. If the mixing volume or product strength changes, the mL marks would need to be recalculated even if the mg targets stayed identical.
This is where a reconstitution calculator becomes useful. The protocol defines the week-by-week mg target, while the calculator confirms the actual draw volume that matches the concentration being used.
NAD+ Calculator or Planning Tool
Once the week-by-week NAD+ plan is locked in, a measurement tool makes the rest faster. It confirms the draw volume for your concentration so you can save the schedule and move on.
When you are ready to stop guessing at mL and syringe units, open the full PeptideUniv calculator. It will turn your NAD+ target into an actual draw and let you save the schedule in one place.

If you are reviewing the broader NAD+ context, the reconstitution guide is the most useful companion read for translating a written plan into a measurable draw.
Half-Life, Frequency, and Protocol Planning
NAD+ protocol searches are usually more about schedule structure than about a single half-life number. In practice, the useful planning variables here are the week-by-week ramp, the number of injection days, and how consistently those days are spaced.
That is why this page places frequency and measurement ahead of pharmacokinetic discussion. The schedule only works if it can be repeated clearly from one week to the next.
What Is NAD+?
NAD+ stands for nicotinamide adenine dinucleotide, a coenzyme involved in cellular energy metabolism and redox biology. Protocol interest usually centers on energy-support and healthy-aging discussions rather than on peptide-style receptor targeting.
On a dosage page, though, the practical answer still comes first: how much is used per injection, how often the injections are spaced, and how the measured volume lines up with the intended mg amount.
Frequently Asked Questions About NAD+ Dosage
What are the two NAD+ maintenance options on this protocol page?
The maintenance phase begins in week 3 and can be structured either as 120 mg twice weekly or 80 mg three times weekly. Both options land at the same 240 mg total per week, but they differ in per-injection size and calendar layout.
What is the week 1 NAD+ starting dose in this schedule?
Both schedule options begin with 0.1 mL, which corresponds to 20 mg per injection in the source framework.
How does week 2 change in the NAD+ protocol?
Week 2 steps up to 0.2 mL, or 40 mg per injection, while keeping the same weekly frequency that was chosen from the start.
How often is NAD+ used in the 3-times-weekly option?
The schedule is generally easiest to run on non-consecutive days. A Monday, Wednesday, Friday rhythm is a clean example, but similar spacing works as long as injections are not placed on back-to-back days.
Why do the mL amounts and mg amounts line up so neatly on this page?
Because the supplied schedule implies a constant concentration of 200 mg per mL. If that concentration changes, the milliliter amounts would need to be recalculated.
When should you use a reconstitution calculator for NAD+ planning?
Use one when the target mg dose is already clear and you need to confirm the matching draw volume for the concentration being used. The tool is there to verify measurement, not to decide the protocol structure.
