Stop guessing.
Start knowing.

Paste any health claim — from a podcast, an article, or a supplement label. Protocol turns it into a 21-day test on your own body, then gives you one clear verdict in your data.

KEEP IT

How it works

Three steps. One real answer.

Paste anything

A Huberman quote, an Attia article, a TikTok claim, a label on a bottle. If you can paste it, you can test it.

Run a 21-day test

We design the test, lock your baseline, and read your sleep, HRV, and resting heart rate while you go.

Get your verdict

One clear call in your own data — not someone else’s. Keep it, drop it, or run it longer.

Paste a claim

Every claim becomes a test.

Drop in the exact thing you heard. Protocol reads it, figures out what it’s actually claiming, and builds a test you can finish in three weeks.

✓Understands the claim. A dose, a habit, a protocol — it knows what to measure.
✓Picks the right signal. Sleep, HRV, or resting heart rate, based on what’s being promised.
✓Sets a fair baseline. Your first days establish the line everything is measured against.

Pasted from a podcast

“Two hundred milligrams of magnesium glycinate before bed reliably adds twenty-plus minutes of deep sleep.”

Reads your real data

Your body, not a survey.

No mood sliders. No “how do you feel today.” Protocol reads the numbers your phone already tracks and watches them change against your baseline.

✓Apple Health & Google Fit. Sleep, HRV, and resting heart rate, read automatically.
✓Baseline vs testing days. The dashed line is you before; the solid line is you on the test.
✓Noise-aware. A change only counts when it clears your normal day-to-day swing.

The verdict

One word. No spin.

After 21 days, Protocol gives you a single call and the numbers behind it. Three outcomes, no fine print.

KEEP

It moved your numbers, clearly and past the noise. Worth your money and your time.

DROP

No real change above your day-to-day swing. The hype didn’t hold up for you.

RERUN

A hint of something, not enough to be sure. Run it longer to settle it.

Even a “drop” stays green. We never use red, and we never use fear.

The science, plainly

We measure the change, then tell you how sure we are.

A real test needs a baseline, enough days to clear the noise, and an honest confidence number. Protocol holds all three — and shows its work.

Days in every test. Long enough to clear the noise, short enough to actually finish.

Confidence reported with every verdict, so you always know how sure the answer is.

Signals read from your phone: sleep, HRV, and resting heart rate. Nothing else.

Your data

Built around consent.

We read only the Apple Health or Google Fit data you grant to run your test. Health data is never sold, never used for ads, and raw health values are not sent to AI for verdicts.

Questions

Good to know.

Anything you can paste: a supplement, a dose, a habit, or a protocol from a podcast or article. Protocol reads the claim and turns it into a structured 21-day test on yourself.

We won't design a test around prescription medications, conditions a doctor is treating, or anything that needs lab work. Those belong with your doctor, not an app.

Only the Apple Health or Google Fit categories you grant, such as sleep, heart rate, HRV, resting heart rate, steps, active energy, mindfulness minutes, and body metrics. Health data is never sold or used for ads.

We compare your testing days against your baseline, measure the change, and report how sure we are. If the change clears your normal day-to-day swing, it's a KEEP. If it doesn't, it's a DROP.
