Somebody finally has to answer this question with actual numbers, so it might as well be us: how long does the good feeling last? The vague industry answer ("everyone's different!") is technically true and practically useless. Here's the real timeline, ingredient class by ingredient class — because "an IV" isn't one thing, and its components run on completely different clocks.
The hydration clock: hours to days
The liter of fluids and electrolytes is the fastest-acting and shortest-lived component. You feel it within the session — headache easing, energy lifting, the general un-wilting — and the direct effect carries one to three days, depending entirely on your rebuild rate: Florida sun, training load, coffee, alcohol. Someone who follows a drip with a boat weekend spends it in a day; someone with decent water habits keeps the topped-up feeling most of a week.
The vitamin clock: days to weeks
Here's where the IV route genuinely separates from capsules. B vitamins and vitamin C delivered at full IV dose restock your tissues in a way oral dosing struggles to — and that restock carries several days to a couple of weeks of the steadier-energy, better-baseline effect members describe. They're water-soluble, so your body spends them continuously; stress, alcohol, and training spend them faster. This clock is why the most common member cadence lands at monthly: it roughly matches the natural drawdown.
The NAD⁺ clock: cumulative
NAD⁺ runs on a different logic entirely. Its effects tend to build over days following a session rather than peaking in the first hour, and the member-reported pattern — steadier afternoons, cheaper workouts — is strongest with a regular rhythm rather than one-off sessions. Think of hydration as filling a glass, vitamins as stocking a pantry, and NAD⁺ as maintaining infrastructure: the full guide covers why.
One bag, three clocks: the water runs in days, the vitamins in weeks, the NAD⁺ in rhythms.

What actually determines YOUR number
Five variables set your personal duration, in rough order of impact: your depletion at the start (deeper holes hold fill longer — the first session often feels the most dramatic), alcohol (the great un-doer: diuretic plus B-vitamin burner), heat and training load (Palm Beach summer is a standing withdrawal), sleep (bad sleep spends everything faster), and water habits (the cheap multiplier on everything above).
The honest summary
Expect to feel a quality session for a few days to two weeks, with your lifestyle choosing the endpoint — and expect the one-month mark to be where most people notice the drift returning, which is why monthly membership rhythms exist. Anyone promising a month of magic from one bag is selling; anyone saying it's all placebo hasn't done the math on doses. The truth, as usual, is a timeline.
