CENTURION
Start Here

An overview only an AI can see.

Your GP is one of the sharpest, hardest-working people you will ever meet. Their day belongs — rightly — to the emergencies: the chest pain, the lump, the result that cannot wait. Prevention, the patient work of keeping a well person well, is the one thing there is rarely time for.

Yet prevention is exactly what begins to matter as the years add up. Most of us come to it later than we’d like — the quiet realisation that staying well is easier, and kinder, than getting better. This is where the age of AI changes something real. For the first time, a single mind can hold everypiece of your medical story at once — your history, your bloodwork, what you’re hoping for — and compare it against more research than any doctor could read in three lifetimes.

That is all Centurion is. The overview only an AI can see, given back to you and your doctor in plain words — not to replace the person who cares for you, but to hand them the one thing the clock keeps taking away. So the small choices that shape how you age are finally made with the whole of you in view.

Jonathan Bouzanquet — Founder
Why Centurion Exists

Three bottles. Each with a small dose of calcium. Together, nearly dangerous.

Our founder was doing “the right things” — best protocols, best brands, best research. His bloodwork came back trending the wrong way. Three separate products were each hiding calcium. Stacked, the dose was well over the safe upper limit. Centurion was built so that never happens to you.

Honestly

We don't have ten thousand reviews. We have one thing: a system built from a near-disaster.

Status

In private beta. Early founding members are shaping the analysis before we open it more widely.

Principle

When a marker drifts toward danger, the AI tells you: “Show your doctor — soon.”

5 – 8 minutes

Fill in the health profile.

The full medical questionnaire. Diagnosed conditions, medications, surgeries, pregnancy status, kidney and gallbladder history, family history, allergies, and goals. Every answer is cross-checked against supplement interactions automatically — the more complete your list, the safer the recommendation.

What happens

This is where the AI learns you. It is also where we find the things that should stop a recommendation before it ever starts.

Upload your blood test.

You can skip this and still receive guidance. But with your blood panel, the AI stops recommending based on demographic likelihoods and starts recommending based on your numbers. Don't have recent results? Our Blood Test Guide tells you exactly what to ask your doctor or pathology clinic for.

What happens

Upload a PDF or photograph. The AI parses it, maps every marker to longevity-optimal ranges, and flags trajectory — not just abnormality.

See what the AI found.

Your protocol: what to take, what to skip, what dose, what form, what to retest in six months. Every compound is tagged with its evidence tier and the reason it was chosen for you specifically. Any marker drifting toward danger is flagged with a single instruction: show your doctor — soon.

What happens

This is the moment Centurion becomes yours. You decide what to act on. You decide what to ignore. You leave with the clearest picture of your health you have ever had.
