Fyxel Bot
Meet Fyxel Bot.
Not a general chatbot. Fyxel Bot is a specialist — it answers questions about GLP-1 medications, peptides, and Fyxel itself, drawing on published clinical information and your own logged record.
- GLP-1s & peptides. Storage, reconstitution math, side effects, staying consistent — educational answers from published information.
- The app itself. How the calendar works, what the rings and dots mean, where any setting lives — Fyxel Bot knows every screen.
- Your own record. What you logged, when your last dose was, how your week went.
Fyxel Bot does not provide medical advice, diagnosis, or treatment — decisions about your medication belong with your healthcare provider.
The Schedule
A schedule you can trust.
Every protocol begins as a schedule — daily, weekly, every other day, or the exact weekdays you choose. Fyxel holds the rule and reminds you about an hour before every dose.
And when you log a dose late, Fyxel asks a better question than most trackers: should the schedule shift with you, counting forward from the dose you actually took — or hold its anchor day, no matter when you slipped? That's a setting, per medication. Your rhythm, your rule.
The Calendar
Every day, accounted for.
The calendar is the record's spine: shot days marked in each medication's color, data days in gray, missed scheduled days ringed so they can't hide. Multiple compounds share one calendar without blurring together.
Tap any day to see — or fix — everything about it: doses, estimated level at day's end, weight, side effects, notes. Forgot to log Thursday? Backfill it in two taps.
Estimated Levels
Estimated levels, not guesswork.
Every dose you log decays along its medication's published half-life curve, and overlapping doses stack. The result is a single line: how much is estimated to be active right now, and where it's headed next week.
It's an estimate built from clinical literature — informational, never a measurement of your body. But it turns “I think it's mostly worn off?” into an actual chart.
The Math
Where others guess, Fyxel does arithmetic.
Reconstitution is where kitchen-counter guessing goes wrong most often: vial strength, diluent volume, target dose, syringe units — four numbers people routinely improvise.
Fyxel's calculator makes it arithmetic: enter the vial and the water, get the exact draw. Half-life plotting and titration schedules live in the same toolkit.
Rotation
Sites need rest. Fyxel remembers.
Injection sites need recovery time, and memory is a bad tracking system. Fyxel records where every shot went and suggests the next site in the rotation — abdomen, thighs, arms — so no spot gets overused.
The Record
The whole picture, kept.
Doses are half the story. Fyxel keeps the rest: weight with a trend line, side effects on 0–10 severity scales, calories and protein, daily notes — the details your follow-up appointment actually asks about.
Everything is yours to keep: export the complete record as a CSV anytime.
The Recap
Your progress, told back to you.
Every so often, Fyxel assembles your journey into a swipeable, shareable recap — days tracked, shots taken, adherence, weight range, milestones. A record you can be proud of, in a form you can show.
“Protocols do not fail for lack of knowledge. They fail in the gap between intention and execution.”
