Longevity
NAD+ nasal spray, reviewed for routine fit and expectations.
A non-injection NAD+ format still starts with a review of goals, current supplements, nasal health, medications, and realistic use.

Why patients ask
For patients who prefer a lighter longevity format.
Clinical checks
Nasal format does not remove the need for screening.
Caliber reviews nasal or sinus considerations, current medications and supplements, goals, monitoring needs, and whether availability supports the request.
Safety and availability
Eligibility is part of the experience.
Nasal-spray protocols can cause local irritation and may not be appropriate or available for every patient.
Caliber does not guarantee a prescription, specific medication, pharmacy availability, or outcome. A clinician may recommend another path when online care is not the right fit.
