NAD Injection Frequency: Advertised Schedules Compared With Tested Regimens

No proven NAD injection schedule exists for energy or longevity. Advertised under-skin and IV routines reflect clinic practice provider dosing page. A four-day study of 500 mg IV drips reported short-term tolerability but mixed blood results 2026 IV pilot.

Why isn't there a proven schedule for energy or longevity?

NAD+ is a molecule your cells use to turn food into energy. A structured search of published trials found only a small number of randomized, adequately powered trials of raising NAD and said further trials are needed to determine the optimal method of raising NAD levels systematic review.

A separate review of human and animal intervention studies from January 2010 through October 2025, published in Ageing Research Reviews, reported no eligible trials that tested IV NAD+ itself or muscle-shot NAD+ itself for anti-aging or wellness outcomes. The summary states that advertised drip and shot schedules lack backing from outcome trials Ageing Research Reviews summary.

Researchers looked back at records from paying clients who received 500 mg NAD+ by IV drip or NR, a related NAD compound, by IV drip on four consecutive days and were followed for 30 days. The team recorded no serious side effects and no clinically important changes in liver or inflammation measures, but blood measures tied to energy use varied from person to person 2026 IV pilot.

What do advertised schedules involve and what do they cost?

Advertised under-skin schedules, called SubQ, usually list 50 to 200 mg per shot, two or three times a week, starting at 50 to 100 mg provider dosing page. The shots take seconds and, in these advertised models, a clinician writes a prescription, a compounding pharmacy dispenses multi-dose vials, and you receive training for at-home shots.

Advertised IV schedules, meaning a slow drip into a vein over hours, often list four to six infusions over one to two weeks, then monthly drips of 250 to 500 mg provider dosing page. A 500 mg drip often runs two to three hours, with the rate slowed if you feel flushing or nausea.

One provider page lists SubQ cost at $25 to $75 per injection for multi-dose vials (Regenerated, observed June 2026) provider dosing page. IV requires clinic visits lasting hours, so time and cost build with weekly visits.

What women report

One post in r/Biohackers (date not listed in source) said “Energy levels were really good, sharper mental clarity”. The same post said benefits “were better and more acute in the 2 to 3 days following the drip”. One comment in r/Refills from 6 months ago said “I'm doing 25mg 2x for 2 weeks, 50mg 2x for 2 weeks, then 100mg 2x for weeks”. One post in r/cfs from 4 years ago said “My muscles started aching like I just had a workout”.

These are individual experiences, not proof of what any schedule will do. The pattern is variability. One woman felt a sharper lift for two to three days and worried weekly drips were unaffordable, another titrated slowly over weeks, and another reported muscle aching with a fast heartbeat and night sweats for days. Short lifts, slow titration, and tolerability problems all push frequency up or down in real life.
