NAD+ has its own online clinical questionnaire — your history, medications, and goals.
A real person goes through your history and takes the time to get it right before anything is decided.
If NAD+ isn't right for your history, you'll hear that plainly. That review is the whole point.
Made for your prescription by a licensed U.S. pharmacy and shipped in temperature-safe packaging.
Your care team checks in after it arrives. Adjust with your provider, or cancel at any time.
NAD+ is offered as an injectable. Your provider decides whether it's appropriate — including whether a different treatment would serve you better.

NAD+ is easy to find online and hard to trust there. Promise works the way medicine is supposed to work — a clinician decides, a licensed pharmacy fills, and someone stays accountable to you.
Prescribed for you specifically, after a real look at your health history — never pulled off a shelf.
Your prescription is compounded for you by a licensed U.S. pharmacy — not a mystery vial from an unregulated website.
Temperature-safe shipping, follow-up check-ins, and a care team that answers — before and after your medication arrives.
NAD+ is a coenzyme, not a peptide. It shuttles electrons through the reactions that end in ATP, which is why it sits at the center of cellular energy metabolism.
NAD+ is offered as a compounded injectable. Your provider determines whether it fits your history and sets the protocol.
A licensed provider reads your history, decides whether NAD+ fits it, and sets the protocol.
Cellular energy is a chemistry problem before it is a feeling. Every cell moves electrons from the fuel you eat toward the machinery that makes ATP, and nicotinamide adenine dinucleotide — NAD+ — is the carrier that does most of that shuttling. It is a coenzyme: a small molecule enzymes borrow in order to work.
Promise offers NAD+ as a compounded injectable. The clinical path is the same: a licensed provider reads your health history and prescribes only when treatment is appropriate for you.
NAD+ is not a peptide, which already sets it apart from most of what sits in energy and focus. MOTS-c and SS-31 are short amino-acid chains studied as signals. NAD+ is a cofactor your cells manufacture and spend continuously, and it works as a redox pair: NAD+ accepts a pair of electrons, becomes NADH, hands them to the electron transport chain, and returns to NAD+ to do it again. Glycolysis, the citric acid cycle, and fatty acid oxidation all stall without it.
Published work reports that measured NAD+ levels in several tissues decline with age, and that observation is most of the reason the molecule draws attention in longevity research. Reading it as a battery running down would be too tidy. What the literature describes is a shifting balance between the enzymes that consume NAD+ and the salvage pathways that rebuild it.
NAD+ is not only recycled — it is also cleaved. Two families of enzymes consume it outright as a substrate. Sirtuins use it to strip acetyl groups from proteins, a form of regulation that touches metabolism and gene expression. PARP enzymes use it during DNA repair, and heavy repair demand draws on that same pool. Because both bid against one shared budget, researchers tend to describe NAD+ less as a fuel and more as a currency.
That framing is why the molecule appears in anti-aging and longevity discussions as often as in metabolic ones. It is also where claims get overstated. Describing which enzymes depend on a cofactor is not the same as showing what giving that cofactor does in a person, and the human trial literature remains much smaller than the interest in it.
The category name is a fair description of the biology and a poor description of the sensation. Energy here means bioenergetics: ATP production inside mitochondria. NAD+ is not a stimulant. It has no caffeine-like action, and nothing about the mechanism predicts alertness, wakefulness, or drive.
We say that plainly because the alternative is a promise nobody can keep. A provider can tell you what is understood about the mechanism and what is not. Neither of you can know in advance how a given person responds, and the honest answer to how it will feel is that the research does not answer it.
NAD+ is offered as a 100 mg/mL injectable vial (10 mL). That is a product fact, not a dosing instruction.
Your provider determines whether it fits your history and sets the protocol. A strength printed on a label is not the same thing as your dose, and if a protocol needs to change, it changes with a clinician involved.
Everything starts with an intake questionnaire built for this specific treatment: health history, current medications, what brought you here. A licensed provider reads it and prescribes only if NAD+ is appropriate for you. Not everyone qualifies, and providers decline on medical grounds — that gate is the reason to do this through a clinic.
If you are prescribed, your medication is compounded and dispensed by a licensed U.S. pharmacy, and shipped in temperature-safe packaging, with follow-up check-ins from your care team. NAD+ sits on top of sleep, food, and sane training loads rather than standing in for them. It is one piece of support for a promise you already made to yourself.
NAD+, or nicotinamide adenine dinucleotide, is a coenzyme present in every cell. It works as a redox pair: NAD+ accepts a pair of electrons, becomes NADH, passes them to the electron transport chain, and returns to NAD+ to do it again. Glycolysis, the citric acid cycle, and fatty acid oxidation all depend on that cycle. It is also consumed outright as a substrate by sirtuins and by the PARP enzymes involved in DNA repair. Published work reports that measured levels in several tissues decline with age, which is most of the reason it draws research interest.
A real prescription. NAD+ on Promise is prescribed by a licensed provider after a review of your health history and compounded for you by a licensed U.S. pharmacy. It is not a product labeled for laboratory use.
No. A licensed provider reviews every NAD+ request and prescribes only when it is appropriate for you. If it isn't, you'll be told plainly — that review is the point.
No. NAD+ as offered here is a compounded medication and is not FDA-approved. Compounded medications are not reviewed by the FDA for safety, effectiveness, or quality. It is prepared by a licensed U.S. compounding pharmacy against a prescription written for you specifically, after a licensed provider has reviewed your health history.
You start with the intake form for NAD+, which is its own clinical questionnaire covering your health history, medications, and goals. A licensed provider reviews your answers and prescribes only if NAD+ is appropriate for you. If you are prescribed, your medication is compounded and dispensed by a licensed U.S. pharmacy and shipped in temperature-safe packaging, with follow-up check-ins from your care team.
They sit at three different points in mitochondrial biology. NAD+ is a cofactor — a molecule the reactions themselves consume and regenerate. MOTS-c is a 16-amino-acid peptide encoded in mitochondrial DNA and studied as a signal, mainly through AMPK. SS-31 is a four-amino-acid peptide studied for its affinity for cardiolipin, a phospholipid of the inner mitochondrial membrane, which puts its research interest on membrane structure rather than on signaling or substrate supply. Your provider decides which of the three, if any, fits your history.
No. Energy in this context means bioenergetics — the production of ATP inside mitochondria — not stimulation. NAD+ has no caffeine-like action, and nothing about its mechanism predicts alertness, wakefulness, or drive. We describe what is being studied and why; we do not tell you how it will feel, because the research does not answer that question.
NAD+ sold online without a prescription is usually labeled for laboratory use, with no provider, no pharmacy, and no one accountable if something goes wrong. Promise works the way medicine is supposed to: a licensed provider decides, a licensed U.S. pharmacy compounds your prescription, and a care team follows up.

Energy & Focus
A 16-amino-acid peptide encoded in mitochondrial DNA, studied for AMPK signaling and metabolic homeostasis. The evidence is mostly preclinical, and every request is reviewed by a provider.
Requires an online medical evaluation. Prescribed only when a licensed provider determines it's appropriate.
The latest from the Promise team on NAD+.
Harden and Young found NAD's activity in yeast experiments, with a detailed paper in 1906. The vitamin, Nobel and longevity chapters came later.
The answer starts with your goal and what is causing the tiredness. Oral supplement findings don't establish what NAD+ injections would do for you.
Some swallowed supplements raise blood NAD+. That doesn't show injections make people younger or that a drip into a vein works better than a shot.
