NAD+ comes in three main delivery routes, and they trade dose against convenience. Subcutaneous injection delivers the highest, most reliable dose at the highest price; patches are needle-free and cheaper but lower-bioavailability; nasal sprays are a convenient needle-free middle option. The right choice depends on whether your priority is maximum delivered dose, avoiding needles, or simply staying consistent.
Injection: highest dose, highest price
Subcutaneous NAD+ injection is the reference standard because it delivers the most NAD+ per dose, reliably, into the tissue. It’s also the most expensive route (roughly $150–$280/month) and requires self-injection — the obstacle that sends many people looking at alternatives. If your priority is the strongest delivered dose under clinician supervision, injection leads.
Patch: needle-free, lower dose
Transdermal patches remove the needle and lower the price (~$95–$160/month), at the cost of absorption — through-the-skin delivery is less efficient than injection, so a patch delivers a smaller effective dose. For the needle-averse or the needle-fatigued, that trade can be worth it if it means actually staying consistent. More detail in our best NAD+ patches guide.
Nasal spray: the middle option
Nasal delivery (~$125/month) is another needle-free route, generally sitting between patch and injection on absorption, though it varies by formulation. It suits people who want more than a patch delivers without moving to injections.
Comparison at a glance
| Route | Typical price/mo | Delivered dose | Needles | Best for |
|---|---|---|---|---|
| Injection (subcutaneous) | $150–$280 | Highest, most reliable | Yes | Maximum effect, supervised |
| Nasal spray | ~$125 | Middle (varies) | No | Needle-free with more dose than a patch |
| Patch | $95–$160 | Lower | No | Needle-averse, consistency |
| Cream | ~$95 | Lowest | No | Gentlest entry |
How to choose
Pick the route that fits the priority you’ll actually stick with. Dose-maximizers → injection. Needle-averse → patch or nasal. Undecided → a provider with multiple formats lets you start gentle and step up. Whatever the route, a clinician-supervised program means someone is matching dose and format to you — see the full provider comparison, where treatment plans start at $129 per month.
NAD+ is prepared by a state-licensed compounding pharmacy and is not an FDA-approved finished product. Delivery-route comparisons describe general absorption characteristics, not guaranteed outcomes. Nothing here is medical advice.
Frequently asked questions
Which method works best? Injection for delivered dose; patch/nasal for needle-free convenience.
Is a patch as good as an injection? Not on dose — it absorbs less, but wins on convenience.
How well does nasal absorb? Between patch and injection, varying by product.
Cheapest form? Cream/nasal, then patch, then injection.
Start with a patch, switch later? Yes — many do; a multi-format provider makes it easy.
