How the NAD+ Loading Phase and Maintenance Phase Work

The NAD+ loading phase is the first of two stages in a typical NAD+ protocol. The loading phase brings your levels up to a working baseline. The second stage, maintenance, holds them steady over time. In the AHC Longevity program, both stages are handled the same operational way. You complete an intake, a licensed provider reviews it, and your personal instructions arrive by email. NAD+ is a compounded product and is not FDA-approved. NAD+ can also be compounded with GLP-1 medication, but only after a provider consultation that costs $250 for all doses.

The NAD+ loading phase is the opening stage of a two-part NAD+ protocol, and it is one of the most common questions people ask before they start NAD+ injections. This post explains what a loading phase and a maintenance phase mean as concepts, how the AHC Longevity program runs from intake to delivery, and where the NAD+ with medication option fits in. We will not print a dosing schedule here. Every specific instruction comes from a licensed provider and arrives in your dosage email, because your protocol is built around you, not around a chart on a webpage.

NAD+ stands for nicotinamide adenine dinucleotide, a coenzyme your cells use in normal metabolic processes. You can read a neutral overview of NAD metabolism through the National Center for Biotechnology Information. What matters for this article is simpler. NAD+ is offered inside the AHC longevity program as a compounded injectable, and it is typically structured across two phases.

What the NAD+ loading phase means

Think of the NAD+ loading phase as the on-ramp. When you begin many longevity injectables, the goal of the early stage is to move from wherever you are now up to a functional working level. The NAD+ loading phase is the concept of building toward that level in a deliberate, provider-guided way rather than starting and stopping at random.

The word “loading” describes intent, not a fixed number. It means the early part of the NAD+ protocol is oriented around establishing a foundation. During the NAD+ loading phase, your body is being brought to a starting baseline that a provider considers appropriate for you. Nothing about that is one-size-fits-all, which is exactly why the specifics live with your provider and your dosage email.

A few plain points about the NAD+ loading phase:

• It is the first stage of a two-phase NAD+ protocol, not a separate product.
• Its purpose is to reach a working baseline, not to rush.
• It is guided by a licensed provider, never self-directed.
• The exact route, amount, and timing are decided by a licensed provider and sent to you privately.

Results vary by individual and depend on adherence, clinical guidance, and lifestyle factors. No two people start from the same place, and the NAD+ loading phase exists precisely to respect that difference.

What the NAD+ maintenance phase means

Once the opening stage is complete, an NAD+ protocol usually shifts into a NAD+ maintenance phase. If the NAD+ loading phase is the on-ramp, the maintenance phase is the cruising speed. The idea is to hold a steady state over time rather than to keep building.

Maintenance is about consistency. After a baseline is established during the NAD+ loading phase, the goal changes from reaching a level to sustaining it. That is the whole concept, a longer and steadier rhythm that a provider sets and adjusts as needed. Some people stay in a maintenance rhythm for a long stretch. Others revisit it with their provider. Because this is a clinical decision, the cadence and amount are never posted publicly and never fixed by a blog.

Here is the distinction stated cleanly. Loading is about getting to a baseline. Maintenance is about staying there. Both are stages of the same NAD+ longevity approach, and both run through the same AHC workflow.

NAD+ loading phase vs maintenance phase, side by side

The table below compares the two stages as concepts only. It contains no amounts, no frequencies, and no schedule. Those details are clinical and come from your provider.

Notice the last three rows are identical. That is the point. Whatever stage you are in, AHC handles it the same operational way, and the specifics always route to a clinician.

Why an NAD+ protocol uses two phases

People often ask why the NAD+ loading phase and maintenance structure exist at all. The short answer is that it separates two different jobs. Reaching a baseline and holding a baseline are not the same task, so a thoughtful NAD+ protocol treats them as distinct stages.

Structuring the protocol this way also keeps the plan honest about individual variation. Your starting point is your own. Your response is your own. A phased approach gives a provider room to guide the NAD+ loading phase, then settle into a maintenance rhythm that fits you. This is the biology-first view, your cells, your metabolism, your pace. It is not a matter of trying harder.

What a two-phase NAD+ protocol is not, it is not a promise. NAD+ injections do not stop or reverse aging, and AHC does not claim energy, performance, or any specific outcome from either phase. The phases describe how a protocol is organized, nothing more. Results vary by individual and depend on adherence, clinical guidance, and lifestyle factors.

How the AHC Longevity program works operationally

This is the part you can plan around. The AHC Longevity program runs on a fixed order flow, and it never changes based on which phase you are in. Approval is never automatic, and payment never guarantees medication.

Here is the sequence, in order:

1. Intake form. You complete one intake per medication. This is where you share your health information for review.
2. Payment at submission. Payment is taken when you submit the intake. It is a request for review, not a purchase of a guaranteed product.
3. Licensed provider review. An independently contracted, U.S.-licensed clinician reviews your intake. They decide whether NAD+ is appropriate and what your protocol should be.
4. Prescription recorded internally. If approved, your prescription is recorded.
5. Dosage instructions emailed. Your personal instructions, covering your stage and your specifics, arrive by email. This is the only place your NAD+ dosing lives.
6. Cold chain express shipping. Your order ships cold chain express, included free, within the United States only.

A few operational facts that hold across both the NAD+ loading phase and maintenance stages:

• Order processing typically takes 1 to 2 business days.
• Delivery typically lands within 4 to 12 business days, US only.
• You get an email confirmation with a tracking number as soon as it is generated.
• Ice packs are a temperature buffer. Your NAD+ is not expected to arrive frozen, and it stays stable in normal transit.

NAD+ is compounded by state-licensed pharmacy partners held to the same quality and safety standards. If you want to see how the wider program is organized, the AHC longevity program page lays out the injectables offered alongside NAD+.

NAD+ injections and how dosing is handled

Let us be direct about dosing, because it is the thing this article deliberately does not do. We do not publish NAD+ dosing amounts, frequencies, or a schedule for either the NAD+ loading phase or the maintenance phase. That is not an oversight. It is policy, and it protects you.

Dosage instructions are sent by email after provider approval. If you need a dosage change at any point, contact AHC support. Our medical officer reviews every request. That path is the same whether you are in the NAD+ loading phase or a steady maintenance rhythm.

This is also why “titration” is worth understanding as a concept. Titration simply means adjusting a protocol under clinical guidance rather than jumping to a fixed endpoint. The NAD+ loading phase often reflects that idea, a measured build, guided by a provider, tied to how you respond rather than to a date on a calendar. You do not manage that yourself, and you do not need a chart to start. You need a provider.

If anything feels wrong during your NAD+ protocol, do not troubleshoot at home. If you experience severe symptoms, contact AHC support or seek medical care. For everyday questions, contact AHC support through live chat on the website or at [email protected].

NAD+ with GLP-1 medication and the $250 consultation option

Some people in the Longevity program also ask about combining NAD+ with GLP-1 medication such as compounded tirzepatide. AHC does offer NAD+ compounded with medication, but there is a firm gate in front of it. It is available only after a provider consultation, and that consultation costs $250 for all doses.

That price is the one number in this article, and it is specific. It is $250, all doses, consultation required. It is not a plan price and it is not a shortcut. A licensed provider still has to review your situation and decide whether the combination is appropriate for you. If you want to read more about that pairing before you start, see NAD+ with tirzepatide at AHC.

Compounded tirzepatide is itself a compounded product and is not FDA-approved. Pairing it with NAD+ does not change that, and it does not change the NAD+ loading phase and maintenance concepts described above. It simply adds a required consultation step and a defined cost before anything is compounded together.

Compounded medications are prepared by state-licensed compounding pharmacies. They are not FDA-approved and have not been reviewed by the FDA for safety, efficacy, or quality.

Recap of how, why, when, and what

• How it works. Intake, payment, provider review, recorded prescription, dosage email, cold chain shipping. Same flow for every stage.
• Why two phases exist. The NAD+ loading phase reaches a baseline and the maintenance phase holds it, two different jobs, and a phased NAD+ protocol respects individual variation.
• When things happen. Processing in 1 to 2 business days, delivery in 4 to 12 business days, and dosing timing set by your provider, never by this page.
• What you receive. A compounded NAD+ injectable and a personal dosage email, with support one message away.

Start your NAD+ evaluation

If a two-phase NAD+ protocol sounds like a fit, the next step is a review, not a purchase. A licensed provider decides what is appropriate for you, including whether you start with an NAD+ loading phase and how a maintenance rhythm might follow. You can begin your evaluation or speak with a licensed provider to get your questions answered first. For a fuller list of how the program runs day to day, browse the AHC patient FAQs.

Frequently asked questions

What is the NAD+ loading phase in the AHC Longevity program?

It is the opening stage of your NAD+ protocol, where the goal is to reach a working baseline under provider guidance. In the AHC program, the specifics of your NAD+ loading phase are decided by a licensed provider and sent to you in your dosage email, never posted publicly.

How is the NAD+ maintenance phase different from loading?

The NAD+ loading phase builds toward a baseline. The NAD+ maintenance phase holds that baseline steady over time. Both stages run through the same AHC intake, review, and dosage-email process, and both are adjusted only by clinical review.

Will AHC tell me my exact NAD+ dosing on this page?

No. AHC does not publish NAD+ dosing amounts, frequencies, or schedules for the NAD+ loading phase or the maintenance phase. Dosage instructions are sent by email after provider approval. If you need a change, contact AHC support and our medical officer reviews every request.

Is NAD+ FDA-approved?

No. NAD+ is a compounded product. Compounded medications are prepared by state-licensed compounding pharmacies. They are not FDA-approved and have not been reviewed by the FDA for safety, efficacy, or quality.

Can I get NAD+ compounded with my GLP-1 medication?

Yes, but only after a provider consultation. NAD+ compounded with medication is available for $250, all doses, and a licensed provider must review whether the combination is appropriate for you first.

How does the NAD+ order process work at AHC?

You complete an intake, pay at submission, and a licensed provider reviews it. If approved, your prescription is recorded, your dosage instructions are emailed, and your NAD+ ships cold chain express. Approval is never automatic, and payment never guarantees medication.

How long until my NAD+ arrives?

Processing typically takes 1 to 2 business days, and delivery typically lands within 4 to 12 business days, US only. You get an email confirmation with a tracking number as soon as it is generated. AHC does not promise a specific delivery date.
