NAD+ Injections: The Complete At-Home Guide
- Self-administered at home — Subcutaneous injection into fatty tissue using small insulin-style needles
- 40-60% bioavailability — Better than oral supplements (5-30%), less than IV (100%)
- Cost range — $50-$350/month vs $250-$1,500 per IV session
- Typical protocol — 2-3 injections per week, 100-200mg per dose
- Requires prescription — Available through telehealth providers like AgelessRx and Shed
What are NAD+ injections?
NAD+ injections deliver nicotinamide adenine dinucleotide directly under your skin (subcutaneous) or into muscle tissue (intramuscular). Unlike oral supplements that must survive your digestive system, injections bypass the gut entirely.
Most NAD+ injections prescribed through telehealth are subcutaneous—you inject into fatty tissue on your abdomen, thigh, or upper arm using a small insulin-style needle. The process takes about 30 seconds once you get comfortable with it.
If you’re new to NAD+ entirely, start with our guide on what NAD+ is and why it matters.
How NAD+ injections work
When you inject NAD+ subcutaneously, it absorbs through the tissue and enters your bloodstream over several hours. This creates a slower, more sustained release compared to IV therapy’s immediate flood of NAD+.
| Delivery method | Estimated bioavailability |
|---|---|
| IV infusion | ~100% |
| Subcutaneous injection | 40-60% (estimated) |
| Oral supplements | 5-30% |
The slower absorption means you won’t feel the intense rush (or discomfort) that IV patients often report. Most people notice subtle energy improvements over days to weeks rather than immediately after injection.
NAD+ injections vs IV therapy
Both methods deliver NAD+ directly into your system. The differences come down to cost, convenience, and how you feel during treatment.
| Factor | Injections | IV therapy |
|---|---|---|
| Cost | $50-$350/month | $250-$1,500/session |
| Location | Home | Clinic |
| Time | 30 seconds | 2-4 hours |
| Bioavailability | ~40-60% | ~100% |
| Discomfort | Minimal | Nausea, flushing common |
| Frequency | 2-3x weekly | Weekly to monthly |
Choose injections if:
- You want at-home treatment convenience
- Cost matters to you
- You’re comfortable with self-injection
- You prefer gradual, sustained effects
Choose IV therapy if:
- You want maximum absorption per session
- You don’t mind clinic visits
- You have specific goals (addiction recovery, acute illness)
- You prefer supervised treatment

How to self-administer NAD+ injections
Self-injection sounds intimidating if you’ve never done it, but subcutaneous shots use tiny needles and become routine quickly. Your telehealth provider will walk you through the process during your consultation.
What you’ll need
- NAD+ vial (prescribed)
- Insulin syringe (typically 29-31 gauge)
- Alcohol swabs
- Sharps container for disposal
Step-by-step process
Prepare your supplies
Wash your hands thoroughly. Gather your vial, syringe, and alcohol swabs. Let the vial reach room temperature if refrigerated.
Draw the medication
Clean the vial’s rubber stopper with an alcohol swab. Pull back the syringe plunger to your prescribed dose amount (filling with air). Insert the needle into the vial, push in the air, then invert and draw your dose. Tap out any air bubbles.
Choose your injection site
Abdomen: 2 inches from navel, avoiding the belt line. Thigh: Front or outer middle third. Upper arm: Back of the arm. Rotate sites to prevent tissue irritation.
Clean and inject
Swab the injection site with alcohol. Pinch a fold of skin, insert the needle at a 45-90 degree angle, and push the plunger slowly. Release the skin fold, withdraw the needle, and apply light pressure.
Dispose safely
Place used needles in a sharps container. Never recap needles or throw them in regular trash.
Tips for easier injections
- Ice the area for 30 seconds beforehand if you’re needle-sensitive
- Inject slowly to reduce discomfort
- Relax the muscle in your injection area
- Stay consistent with timing (same days each week)
Dosing protocols
NAD+ injection dosing varies by provider and individual needs. There’s no FDA-approved standard dose, so protocols come from clinical experience and provider judgment.
| Protocol | Dose | Frequency | Notes |
|---|---|---|---|
| Conservative | 50-100mg | 2x per week | Assess response over 4 weeks |
| Standard | 100-200mg | 2-3x per week | Adjust based on response |
| Higher-dose | 200-300mg | 3x per week | For specific therapeutic goals |
Your prescribing provider will recommend a starting dose and adjust based on how you respond. More isn’t always better—some people do well on lower doses.
Where to get NAD+ injections
NAD+ injections require a prescription. You can’t buy them over the counter, and you shouldn’t trust sources that don’t require medical evaluation.
Telehealth providers
AgelessRx — Offers NAD+ injections, nasal spray, and patches. Virtual consultation required. Ships nationwide.
Shed — Primarily known for GLP-1 medications but also offers NAD+ as part of longevity protocols. If you’re already using Shed for weight loss, you can add NAD+.
Other options: Eden Health, Defy Medical, and various longevity-focused telehealth clinics.
What to expect from the process
- Complete an intake form (medical history, current medications, health goals)
- Virtual consultation (video or phone call with a licensed provider)
- Prescription sent to a compounding pharmacy if approved
- Vials shipped to your home with supplies
- Follow-up check-in after 4-8 weeks
Red flags to avoid
- No medical consultation required
- Prices that seem impossibly low
- No clear information about the pharmacy source
- Pressure to buy without evaluation
Cost overview
NAD+ injection costs vary widely based on dosage, provider, and whether you’re buying single vials or subscriptions.
| Item | Typical cost |
|---|---|
| Per vial (multi-dose) | $75-$200 |
| Monthly subscription | $150-$350 |
| Consultation fee | $0-$150 (often waived with subscription) |
Compared to IV therapy at $250-$1,500 per session, injections offer significant savings—especially for ongoing maintenance protocols.

Side effects and what to expect
Most people handle NAD+ injections fine. Side effects exist but tend to be mild.
Common injection site reactions
- Redness at injection site (temporary)
- Mild bruising (especially when starting)
- Itching or warmth (usually resolves in minutes)
- Small lumps that absorb over hours
Systemic effects (less common)
- Mild nausea — less common than with IV, but possible
- Flushing — warm sensation, particularly at higher doses
- Fatigue — some people feel tired initially before energy improves
- Headache — usually mild, often from dehydration
Most side effects diminish as your body adjusts. Staying hydrated helps reduce systemic effects.

Who should consider NAD+ injections?
Good candidates
- Adults over 40 seeking anti-aging support
- People with unexplained fatigue or low energy
- Those interested in longevity protocols
- Anyone who’s tried oral NAD+ supplements without results
- People who want more than supplements but can’t afford regular IV sessions
May not be ideal for
- People uncomfortable with self-injection
- Those seeking immediate, dramatic effects (IV may be better)
- Anyone with bleeding disorders or on blood thinners
- Pregnant or breastfeeding women (insufficient safety data)

What results to expect
NAD+ injections don’t produce overnight transformations. Most people notice gradual improvements over weeks.
| Timeline | What to expect |
|---|---|
| Week 1-2 | May notice subtle energy changes, improved sleep |
| Week 3-4 | Energy and mental clarity improvements more noticeable |
| Week 6-8 | Cumulative benefits become clearer |
| Ongoing | Maintenance dose to sustain benefits |
Individual results vary. Some people feel differences within days; others need months to notice changes. Age, baseline NAD+ levels, diet, exercise, and sleep all influence outcomes.
Frequently asked questions
The bottom line
NAD+ injections offer a practical middle path: more absorption than oral supplements, more affordable and convenient than IV therapy. They require a prescription and some comfort with self-injection, but for many people, that trade-off makes sense.
If you’ve been curious about NAD+ therapy but the cost or time commitment of IV treatments put you off, injections are worth looking into.
