NAD+ guides

Subcutaneous or intramuscular, at home, as the physician and pharmacy direct: what the pharmacy sends, how long it takes and how the vial is stored.

What the cited studies measured, in whom and in which form, and why a photo is not evidence.

What determines the per-vial price, how to read quotes given in different units, and why it is cash-pay.

Injection-site and allergic reactions, flushing and nausea with rapid infusion, what to report the same day, and what the physician asks first.

No approved label means no dosage chart. How a physician sets dose, route and schedule, and what a vial concentration means.
