A physician-supervised loading protocol — five 750mg infusions over two weeks — followed by subcutaneous maintenance. Built for Tennessee Valley patients who want longevity medicine without the trip to Atlanta.
Reserve Founding Membership See the ProtocolNAD+ (nicotinamide adenine dinucleotide) is the coenzyme that powers mitochondrial energy production, DNA repair, and sirtuin activation — the cellular pathways that determine how well you age. By age 50, most adults carry roughly half the NAD+ levels of their 20-year-old self. The downstream effects are mitochondrial dysfunction, slower recovery, blunted cognition, and accelerated senescence.
NAD+ IV therapy is the most direct way to restore intracellular levels. Oral precursors (NMN, NR) work — slowly. Subcutaneous injection works — moderately. IV NAD+ saturates tissue NAD+ stores within hours, which is why Dr. Hare uses it as the loading phase of every longevity protocol at Limitless.
Five infusions over two weeks, each at 750 mg, delivered slowly over 2–3 hours under physician supervision. After loading, most patients transition to once- or twice-weekly subcutaneous maintenance dosing at 100–200 mg, which can be self-administered at home with portal-based titration.
Limitless is at 1502 Dug Gap Road in Dalton, Georgia — a 25-minute drive from downtown Chattanooga via I-75. For the loading phase you'll come in five times across two weeks; many Chattanooga patients schedule afternoon infusions to anchor a working-from-home day. After loading, maintenance is delivered at home via SubQ injection — no more drives unless you want one.
