Experiment with your body

Your virtual biology lab.

Experiment with changes to your diet, supplements, medications, and training. See how your body responds - before you live through it.

1,200+ inputs
Food, exercise, meds, supplements, etc. Every effect cited.

What the lab lets you do

Three things you can do nowhere else.

Run virtual experiments.

Drop new compounds, doses, meals, or training onto your timeline — and compare the response side-by-side with your baseline.

A · Baseline72
B · w/ Creatine84

See every signal respond.

Cortisol, dopamine, mTOR, ApoB, HRV — 62 modeled signals move in real time as you drag inputs around the day.

Iterate in afternoons, not months.

Fork the day, change one variable, re-run. The protocol that beats every version you tried is written down with the doses that earned it.

The questions people are asking.

Real prompts from the closed beta. Doses preserved, identities removed. Nothing here is a recommendation — they're the shape of what a self-clinician asks the lab to model.

GLP-1 · 41M
12-week scenario

Muscle-first tirzepatide.

10 mg/wk titration with three protein bumps, two resistance sessions, and electrolyte support. Lab flags catabolism risk on day-3 of every dose week.

Performance · 38M
14-day scenario

Two-pulse caffeine, no afternoon stims.

Replaced a 600 mg/day caffeine + nicotine loop. 100 mg AM, 100 mg before lunch, hard cutoff. HRV +9 ms in two weeks.

CaffeineHRVSleep
Conditions · 41F
16-week scenario

Hashimoto's + perimenopause + iron low.

Levothyroxine timing, alternate-day iron repletion, magnesium PM, structured light exposure. Ferritin +28 ng/mL modeled.

Hashimoto'sIronPerimenopause
ADHD · 33F
12-week scenario

Natural-baseline dopamine, alongside Vyvanse.

Bright light, protein-led morning, training, magnesium L-threonate, tyrosine timing. No dose change. 3 PM crash flattened.

Why simulate

Why not just try it in real life?

You can. But reality is slow — and it only lets you run one experiment at a time.

Weeks
A sleep experiment
Months
A supplement trial
A quarter
A blood marker to move

The lab lets you test ten ideas before you've finished testing one.

The scientific standard

Every modeled effect has a citation. Every effect curve in the lab is traced to a published study.

✓

Modeled with real mathematics.

Pharmacokinetics, half-lives, absorption, clearance, mass conservation - the equations clinical pharmacology uses, applied honestly.

✓

Every effect has a citation.

Every biological effect has a published scientific paper to go with it. If we can't cite it, we don't model it.

✓

Transparency around data quality.

Some predictions are backed by hundreds of human studies. Others are educated estimates. The lab tells you which is which.

Who it's for

The lab for the
self-clinician.

Built for people who already run experiments. People tracking bloodwork. People reading studies. People managing chronic conditions. People comparing interventions. The lab is built for what you do next.

Pricing

One bad experiment costs more than a month of access.

Most people spend hundreds testing protocols blindly. Simulate first, buy later. Founding-member pricing locks for life. Cancel anytime. Every protocol exports as JSON the day you decide to leave.

★★★★★

"This is what I wish I'd had on day one of my GLP-1. Twelve months of mistakes I now would have avoided."

★★★★★

"I caught a duplicate in my stack the first afternoon. Saved me from a tolerance break I was about to start."

★★★★★

"Finally a tool that doesn't pretend to be my doctor. The receipts on every effect are the whole point."

Your body isn't a black box.
Stop treating it like one.

A sleep experiment takes weeks. A supplement trial takes months. A blood marker can take an entire quarter. The lab lets you test ten ideas before you've finished testing one.

Also from Protokol · Free forever

Or just need a GLP-1 tracker?
We made that too.

Protokol Tracker is the free companion app — macros, doses, weight, symptoms, and photos in one place. Built around half-life curves and a rolling 7-day budget instead of the midnight reset every other tracker uses. Use it alongside the Lab, or completely on its own.

Half-life curves
Tirzepatide, Semaglutide, Mounjaro, Zepbound, Ozempic, Wegovy — pre-loaded.
Rolling 7-day
Unused calories carry forward. Off-days don't break streaks.
