Why a real tracker

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.

01

Dose timing

When to inject, what changes if you're a day late, and when the effect starts to fade. Hard to feel, easy to measure.

02

Effects no one warned you about

Nausea, fatigue, constipation. Logging severity over the weeks reveals the pattern before it becomes a problem.

03

Losing muscle along with the weight

The scale drops, but not every pound is fat. Tracking measurements and wellbeing gives you the full picture.

04

Site rotation

Always injecting in the same spot hurts. A 2D body map remembers where the last shot went — and suggests the next.

05

Scattered data

Spreadsheets, screenshots, apps that sell your health information. Your protocol deserves one place — and a private one.

Bymax Bio solves every one — on your device.

Pharmacokinetic intelligence
01 / 03

Rises, peaks, decays.

Bymax Bio estimates your medication's relative activity from your shots — and draws the entire curve, dose after dose.

02 / 03

Know when the effect drops.

The curve doesn't stop at today: it runs on to your next dose, showing the decay. No guessing — you see exactly where you are on it.

03 / 03

Anticipate the best moment.

See how your appetite pattern tracks the curve — and talk timing with your doctor using data, not hunches.

Frictionless logging

Log a shot
in 4 taps.

Medication, dose, date and time, and the site on your body. A 2D figure shows where you injected last time and suggests smart rotation — front or back, arm or thigh.

Frequently asked questions

Everything you need to know.

Is Bymax Bio really free?
Yes. The app is free right now — shot logging, reminders, estimated activity, adherence heatmap, multi-protocol and full export. When we turn on paid plans, anyone who already installed keeps free access for as long as they use the app. New users will pay $3.99/month.
Which medications does it track?
GLP-1 (semaglutide — Ozempic®, Wegovy®, Rybelsus®; tirzepatide — Mounjaro®, Zepbound®; liraglutide — Saxenda®, Victoza®; retatrutide and orforglipron), recovery peptides (BPC-157, TB-500), GH peptides (CJC-1295, Ipamorelin, Hexarelin, GHK-Cu, Epithalon), hormones (testosterone cypionate, enanthate and propionate, nandrolone, HGH, oral and transdermal estradiol, progesterone), metformin and injectable vitamins (B12, D3, MIC). That's 25 curated medications across 6 classes, and you can add your own.
Is my data safe?
Your data never leaves your device. There's no sign-up, login or server — everything is stored locally. The app works offline and you can erase everything at any time. The only thing the app shares is anonymous usage statistics, with no health data whatsoever — and you can turn that off in Settings › Privacy.
Does Bymax Bio give medical advice?
No. Bymax Bio logs, it doesn't prescribe. It organizes your data and presents it clearly — including a PDF for your doctor — but any decision about dose or treatment is between you and a healthcare professional.
How does the estimated medication activity work?
From your logged shots and each medication's estimated half-life, the app works out your estimated activity and draws a single curve — peak to decay — with a dot marking the current moment. It's a relative scale: how much you still have on board, not a lab value. It needs at least 3 logged shots, and you turn it on in Settings › Tools.
Does it work on iPhone and Android?
Yes, on both. And the interface is native in Portuguese, English and Spanish — with copy curated per language, not machine translation.
Can I export to bring to my appointment?
Yes. Export a formatted PDF report and CSV files, filtered by 30, 90 or 180 days, everything or a custom range, and share via WhatsApp, email or AirDrop in seconds.
