Your biohacking protocol,
live.
Bymax Bio is the tracker for GLP-1, peptides, TRT and injectable vitamins: log every shot, see your medication's estimated activity, and export a report ready for your doctor. Your records stay on your device — no sign-up.
Managing a protocol is harder than it looks.
Pen, peptide, hormone or vitamin — the hard part is never the shot. It's everything that happens around it.
Your dose history
When you injected, which dose and where. From memory it fades within weeks; logged, it becomes a history for your appointment.
Effects no one warned you about
Nausea, fatigue, constipation. Logging intensity over the weeks gives your doctor a record of what happened and when.
Losing muscle along with the weight
The scale drops, but not every pound is fat. Logging measurements and wellbeing alongside weight helps the conversation with your doctor.
Site rotation
Labels for subcutaneous medications ask you to change the injection site. A 2D body map remembers where your last subcutaneous shot went — and suggests the next.
Scattered data
Spreadsheets, screenshots, loose notes. Your protocol deserves one place — and a private one.
Bymax Bio helps you log every one — on your device.
Rises, peaks, decays.
An optional feature: from your logged shots and catalog averages, Bymax Bio draws a relative curve of estimated activity — dose after dose.
A drawing, not a measurement.
The curve runs on to your next dose and shows the estimated decay. 100% is the peak of your own pattern, not a lab value or an effect.
Something to discuss with your doctor.
Bring the curve and your records to your appointment. It doesn't tell you when to inject or change your dose — that's for whoever oversees your treatment.
Log a shot
in 4 taps.
Medication, dose, date and time, and the site on your body. On subcutaneous shots, a 2D figure shows where you injected last time and suggests the next site — front or back, arm or thigh.
- Date shortcuts: Now · Yesterday · Other…
- Reuse your last dose with one tap
- 2D site map, with rotation suggestions for subcutaneous shots

A tour of the app.
See the next step in your day.
Next dose with a countdown, your week at a glance, weight and effects — and the log button always within reach.
Log the shot and the site.
Four taps and, for subcutaneous shots, a 2D figure that suggests the next site.
Track weight and measurements.
Adherence heatmap, weight curve and waist, hip, chest and arm — all correlated.
Monitor effects and wellbeing.
Weight, measurements, side effects (1–5) and wellbeing in a radial menu, to log in seconds. Nutrition has its own tab, and the cycle gets one too once you turn on Female health in Settings.
It's not just GLP-1.
26 curated medications across 6 classes — GLP-1, peptides, hormones, metformin and injectable vitamins — plus your own custom ones.
Your health records stay on your device.
There's no account to create. Records live in a local database and leave your device when you export and share them. Usage data and crash reports start on, and you can turn them off. In the European Union, Norway, Iceland, Liechtenstein and the United Kingdom they start off until you turn them on.
No sign-up, no login
No email, no password. You open the app and start.
Records on your device
Health records live in a local database and work offline. What uses the network: exports you share, usage data and crash reports (you can turn them off; the crash-report filter isn't yet verified in production), RevenueCat (subscriptions) and the update check.
Erase your records whenever you want
In Settings, Delete all data, after a confirmation, erases your records from the device. The local identifier stays, and that action doesn't erase what was already sent.
