The science

The same clocks the longevity world runs on

Liv is powered by TruAge® by TruDiagnostic and includes DunedinPACE, OMICmAge and SYMPHONYAge: peer-reviewed epigenetic clocks developed with leading research institutions.

DunedinPACE

Belsky et al., eLife 2022

Twenty years, 1,037 people, nineteen markers of organ health measured again and again, until the pattern of aging itself could be read from a single blood sample. Yours.

SYMPHONYAge

Sehgal et al., Nature Aging 2025

Your heart and your brain do not age at the same speed. Yale built a way to read eleven separate ages from one blood sample, and show you each.

OMICmAge

Chen et al., Nature Aging 2026

Harvard and Yale built it from the blood and medical records of 31,000 people, then validated it on 33,000 more. One number for your Biological Age.

Evidence it moves

Waziry et al., Nature Aging 2023

In a two-year trial with 220 healthy adults, the people who ate less aged 2–3% more slowly: the strongest randomised evidence we have that the speed of aging can be changed.

What actually worked

Bischoff-Ferrari et al., Nature Aging 2025

Three years, 777 adults, three interventions head to head. Only omega-3 slowed aging on its own. We would rather tell you that than sell you all three.

Eight weeks of sleep

Carroll et al., The Lancet Healthy Longevity 2026

No pill. No supplement. No change to anyone’s diet. Just eight weeks of insomnia therapy, and they were still aging more slowly three years later.

Where would you rank?

Same test, same algorithm, same board. The first call is where we find out what your number is likely to be.

30 minutes. No cost, no commitment.

What you’re actually buying

A measured change in how you age.

The goal we work toward together, set from your baseline: age months slower per year, measured.

  1. Day 1TruAge test

    It starts

    Onboarding call, first epigenetic test, nutritionist session, supplements ship.

  2. Weeks 1–4

    One habit layer per week

    Supplements, then sleep, then movement, then nutrition. Never a pile.

  3. Week 4

    Blood panel

    Longevity blood panel, drawn at home, around your calendar.

  4. Month 2

    Glucose month

    A CGM — a small sensor worn on your arm — reads your glucose around the clock and finds your personal top-5 spike foods.

  5. Month 3TruAge test

    Second test

    Mid-point epigenetic test. The protocol adjusts to what moved.

  6. Months 4–6

    Compound

    A 30-minute minimal-dose strength program adjusted weekly. A protein protocol that survives client dinners.

  7. Month 6TruAge test

    Final Data Pack

    Third test. Your before and after, in numbers.

Throughout

A weekly check-in

Private, with the founders and the science team. Every week, all six months.

A direct line

WhatsApp, answered within 24 hours by someone who knows your data.

Every logistic

Kits, bookings, registrations — done for you.

You hit the gym.We’ll do the heavy lifting.

Six months from now, you will have the numbers.

It starts with one conversation about where you are today and whether now is the moment to commit.

5 spots open. No cost, no commitment.

Guarantee

The Longevity Leaders Guarantee

Leaders commit. They set ambitious goals and do everything they can to achieve them. We can set the goal and arm you with a plan, but you have to take action. If you take all the tests and follow the personally developed plan and don’t achieve your results, we’ll refund you the entire program.

And if your baseline is already excellent: we say so, refund you, and part as friends. We only take members whose data shows real upside.

No cost. No commitment.

For you if: you are building or have built something, you are 30 to 60, your calendar is brutal, you want your health run with the same rigor as your capital, and you will actually do the daily 15 minutes.

Not for you if: you want a silver bullet without changing anything, or your numbers are already elite. (For the second group: congratulations, and we will happily just test you.)

Sounds like you?

We’d rather find that out together than sell you a program that doesn’t fit.

One conversation. We’ll both know quickly.

Questions.

“My doctor already checks me every year.”

Your checkup looks for disease. We measure aging and build the plan between checkups. We are happy to share your data with your physician.

“I travel every week.”

The protocol is built for that: hotel workouts, travel supplement packs, restaurant rules. See The Travel Protocol.

“How much time does this cost me?”

One call a week, and about 15 minutes a day: your supplements, a short morning check-in with Liv, and on training days the 30-minute session. The tests come to you — kits at home, draws arranged around your calendar. We do the rest.

“Is this real science?”

The clocks we use are published, peer-reviewed science: DunedinPACE (Belsky et al., eLife 2022, Duke University), run on the TruAge panel from TruDiagnostic across 150+ epigenetic biomarkers — the same assays the longevity field itself runs on. What they can say, what they cannot, and the honest state of the evidence: that is The Science Briefing, yours in week one. No overclaiming.

“What happens to my data?”

German company, GDPR, your data stays yours, deletion on request.

“Why only 5 members?”

Because this is concierge, not software. From week one to week twenty-six, a founder and the science team hold hours for you every single week. Five members is the number where every member gets that attention. That is the point.

Still have a question?

The first call is the place to ask it — no script, no pitch deck, no obligation at the end.

30 minutes with Amer Hamzeh and Dr. Olena Husak.

5 spots open. Find out if you’re eligible.

30 minutes with Amer Hamzeh & Dr. Olena Husak. We’ll talk about where you are in your longevity journey — what you’re running today, and whether now is the moment to commit. If your numbers are already elite, we’ll tell you. If we can help, we’ll invite you into the program. Nothing to lose but a month at your current speed.

Liv provides informational insights into biological aging and longevity. Liv does not diagnose, treat, cure, or prevent any disease, and is not a substitute for medical advice. Always consult a qualified healthcare professional for medical questions.

1Speed of Aging is measured with the DunedinPACE algorithm (Belsky et al., eLife 2022), included in the TruAge test, taken three times: Day 1, Month 3 and Month 6 of the program. The goal is measured from your Day 1 baseline to the Month 6 test. The gauge animation and the stated goal illustrate what we set together from your baseline, not a promised outcome.
