I started Fyxel because the hardest part of a GLP-1 or peptide protocol is not understanding it. It is executing it — every dose, on time, for months.
The information already exists. Your prescriber gave you a plan. What fails is everything after: the dose that slips a day and quietly resets your rhythm. The reconstitution math guessed at a kitchen counter. The injection site used twice because nobody remembers Tuesday. The question you cannot answer at your follow-up — have I actually been consistent?
Protocols do not fail for lack of knowledge. They fail in the gap between intention and execution. Fyxel exists to close that gap.
It is not a coach, and it is not a doctor. It is a record — a precise one. What you took, when you took it, where it went, and what happened next. This letter explains what that means, chapter by chapter.
The Schedule
Every protocol begins as a schedule. Daily. Weekly. Every other day. Three times a week. Fyxel holds the rule, whatever its shape — anchored to the weekday you chose or to a precise interval — and reminds you about an hour before every dose.
The interesting part is what happens when life intervenes. Log a dose late and most trackers quietly lie to you. Fyxel asks a better question: should the schedule shift with you, counting forward from the dose you actually took — or hold its anchor, keeping Tuesday sacred no matter when you slipped? That is a setting, per medication. Your rhythm, your rule.
A schedule you can trust is the difference between a protocol and a pile of intentions.
A protocol is just a schedule you keep.
Chapters II–VIII — the calendar, estimated levels, the math, rotation, the record, the recap, and the assistant — are being set in type now.
