The ceiling dose.
Longevity 55+ is a 120-minute program — the deeper longevity course, infused slowly over two hours under full clinical attention. It rebuilds the cellular machinery behind metabolism, repair and energy at our highest dose, reserved for clients with an established Longevity 35+ baseline and reviewed bloodwork.
The advanced dose. NAD⁺ at 500 mg, infused over two hours.
- The deepest cellular dose we run, over a calm two hours
- A stronger metabolic lift that lasts up to two weeks
- Deep recovery after illness or sustained stress
- The advanced longevity program, built on your baseline
Diagnostics first, then the treatment.
Every program is one clinical plan, built from your blood. A full panel and a physician read it; the infusion and neurotherapy that follow are written from your results.
Blood biochemistry
A full blood panel and a physician consultation establish what your body needs. Your program is written from the numbers, and the diagnostics are included in the price.
Intravenous infusion
Mixed in our lab the day of your session and dialled to your bloodwork — nutrients straight into your bloodstream at full strength, where your body can actually use them.
Neurotherapy
A precise electrical signal in the same session, tuned to your goal. It primes your nervous system and amplifies what the infusion starts, so one session does more.
The neurotherapy layer.
Every Longevity 55+ program pairs the infusion with targeted neurostimulation, calibrated to the same clinical goal.
Delivered through the same session and tuned to your program’s goal, the neurotherapy settles the nervous system and moves the body into a recovery state — so the infusion works deeper and you feel the result sooner.
The science.
Longevity 55+ doubles the Longevity 35+ dose to 500 mg of NAD⁺ in a single intravenous session. The 120-minute infusion is medically necessary — at this dose, faster delivery causes facial flushing, chest tightness, and occasionally elevated blood pressure.
Doubling the dose increases cellular uptake at saturation but also requires baseline tolerance and case review. We do not run Longevity 55+ as a first NAD⁺ session; clients begin at Longevity 35+, document tolerance and effect, and progress to Longevity 55+ once markers are reviewed.
500 mg is the ceiling dose offered at INFUZE. Above this — at 750 or 1000 mg per session as used in some clinics — the marginal cellular uptake of NAD⁺ in healthy adults is poorly characterised in the literature, while the rate of vagal and cardiovascular side effects rises sharply. We chose to stop at the dose with a documented safety and tolerability margin rather than chase a number.
The program pairs cleanly with quarterly Detox sessions for clients running ongoing longevity programs. Each Longevity 55+ session is mixed in our laboratory and the full dose recorded against your case file.
What the session is like.
Two hours is intentional — a slow, gentle infusion with nothing to push through. Most clients bring a book or sleep through the second half. The room is quiet.
Mental clarity is the typical report afterward; the effect lasts up to two weeks. Clients on the quarterly program often describe a sustained baseline lift after the third session.
Program cadence.
Longevity 55+ requires a baseline session at the Longevity 35+ dose first, plus a documented intake review of current markers. Quarterly cadence is the standard once you're on Longevity 55+ — single doses are not the right framing.
Who it’s for.
Three contexts where Longevity 55+ delivers the most measurable change.
- 01 · Indication
Established Longevity 35+ clients with documented baseline
- 02 · Indication
Post-illness cellular recovery, under case review
- 03 · Indication
Quarterly maintenance once tolerance is confirmed
Before you book.
Why does the session take 2 hours?
Slow infusion is the safety margin. NAD⁺ at 500 mg infused under 90 minutes consistently produces facial flushing, chest pressure, and occasionally a vagal response. 120 minutes is the documented safe range.
Do I need a consultation first?
Yes. Longevity 55+ requires a baseline Longevity 35+ session and an intake review of your current markers and medications before we'll proceed at the higher dose.
Can I sleep through it?
Most clients do. Bring a book, headphones, or a podcast — the room is quiet and the line is comfortable for the duration.
How often should I do Longevity 55+?
Quarterly is the standard cadence after baseline tolerance is established. Some clients run it more frequently during post-illness recovery, with case review every 12 weeks.
