NAD+ Delivery Methods Explained: Injection, Nasal Spray, and Topical Cream
TLDR: NAD+ is available through several routes. At Profusions Health & Wellness, options include subcutaneous injection, nasal spray, and topical cream (we do not offer IV infusion). The right NAD+ delivery method depends on your goals, comfort with self-administration, and how your provider wants the molecule to reach tissues. Delivery is not one-size-fits-all, and a licensed clinician should match the form to your plan.
How you take a therapy shapes how it fits your life. The same active ingredient can arrive as a weekly shot, a spray you use at home, or a cream you apply to skin. That choice matters for convenience, consistency, and how the product is intended to work.
This guide covers the main NAD+ delivery methods patients ask about, with a clear focus on what Profusions offers and how providers think about route of administration.
Why Delivery Method Matters for NAD+ and Peptides
NAD+ (nicotinamide adenine dinucleotide) supports cellular energy pathways. Clinical and regenerative literature discusses multiple methods of administration when teams try to restore or support NAD+-related biology, from systemic approaches to more localized ones (PMC: The Role of NAD+ in Regenerative Medicine).
Route changes:
- How quickly and how broadly exposure may occur
- How easy it is to stay consistent week after week
- Whether the product is aimed more at systemic support or local/skin-focused use
- Training and safety steps (injection technique vs. spray technique vs. topical use)
For peptide and metabolic programs more broadly (for example GLP-1 therapies such as semaglutide), subcutaneous injection is a well-established clinical route for many products designed for systemic effect (NCBI StatPearls: Semaglutide; WEGOVY prescribing information). That context helps patients understand why injections remain common in telehealth wellness protocols when systemic delivery is the goal.
Subcutaneous Injection
What it is: A small injection into the fatty tissue just under the skin, usually with a short needle, often in the abdomen or thigh once a provider has cleared the plan.
Why providers use it: Subcutaneous delivery is a standard way to introduce many peptide and hormone therapies into the body without an IV clinic visit. It supports at-home use after proper training and fits busy schedules better than infusion chairs.
Best fit when:
- Your plan prioritizes systemic exposure under clinician guidance
- You are comfortable with self-injection after instruction
- You want a structured cadence (for example, scheduled doses rather than multiple daily applications)
Practical notes: Technique, site rotation, storage, and timing all matter. At Profusions, licensed providers and clinical support walk you through safe use when injection is appropriate. Compounded preparations are not FDA-approved finished drug products; eligibility and product selection require provider review.
Nasal Spray
What it is: A metered or directed spray into the nasal passages for at-home use.
Why patients choose it: No needles. Fast routine. Easy to travel with once your provider has prescribed it.
How to think about it: Nasal routes appear across pharmaceutical delivery research as an alternative pathway when teams want non-injection options; absorption and consistency still depend on formulation, technique, and individual anatomy (PMC overview on peptide delivery routes including nasal spray). For NAD+ specifically, evidence depth varies by product and claim, so treat marketing language carefully and rely on your clinician for expectations.
Best fit when:
- Needle aversion is a real barrier to adherence
- You prefer a quick daily or scheduled spray habit
- Your provider judges nasal delivery appropriate for your goals
Topical Cream
What it is: A cream applied to the skin as directed.
Why it exists: Some patients want a non-invasive option oriented toward skin comfort, local application, or a gentler on-ramp into a longevity stack. Topical NAD+ products appear in compounding and wellness catalogs alongside injectable and nasal forms (examples of compounded NAD formats in industry practice).
How to think about it: Topical delivery is a different job than a systemic injection. Skin barrier, vehicle (cream base), and application site all change what you should expect. Limited public clinical literature means your provider’s judgment and product quality matter more than social media claims (discussion of multiple NAD routes and evidence gaps).
Best fit when:
- Goals lean local or adjunctive rather than “maximum systemic”
- You want zero needles and simple daily application
- Your clinician includes cream as part of a broader plan (for example, alongside other therapies such as glutathione or peptide protocols when indicated)
What Profusions Offers (and What We Do Not)
Profusions Health & Wellness is a virtual clinic serving patients with licensed providers across all 50 states. For NAD+, confirmed delivery options in our catalog are:
- Subcutaneous injection
- Nasal spray
- Topical cream
We do not offer NAD+ IV infusion. If you see IV-only messaging elsewhere, that is a different care model. Our focus is provider-guided telehealth with discreet shipping and ongoing clinical support.
Other programs in the same high-touch model include GLP-1 / weight loss, sermorelin, TRT, and additional peptides when clinically appropriate.
How to Choose With Your Clinician
Use this simple decision frame on your consult:
| Priority | Often leans toward |
|---|---|
| Systemic, structured dosing | Subcutaneous injection |
| No needles, simple routine | Nasal spray |
| Local / skin-oriented or needle-free adjunct | Topical cream |
| Clinic chair time and IV logistics | Not offered at Profusions (we stay injection / nasal / cream) |
Also ask about:
- Storage and travel
- How side effects or irritation are handled
- How delivery pairs with other therapies (weight loss, hormones, recovery)
- Pharmacy sourcing and quality standards (see our companion article on compounding pharmacy quality)
Bottom Line
NAD+ delivery methods are tools. Injection, nasal spray, and cream each solve a different mix of convenience and clinical intent. The highest-value step is not picking the trendiest format online. It is a short, honest conversation with a licensed provider about goals, medical history, and adherence.
