Protocol Tracker
Track doses, vial usage, and cycle progress across an active peptide protocol. All data stays in your browser — nothing is sent to any server.
What the tracker does
The tracker keeps a log of a protocol you are already following. For each compound you enter a dose, a frequency, a cycle length, a start date, the vial size and the number of vials you have. From those it lays out the days a dose is due, lets you mark each one as taken, and shows how far through the cycle you are, how closely you have kept to the schedule and how much supply is left. It does not suggest doses, schedules or compounds.
How the numbers are worked out
Schedule. Daily and twice-daily entries get one or two doses on every day of the cycle; every-other-day, twice-weekly, three-times-weekly and weekly entries get a dose at the matching interval from the start date.
Adherence is the number of scheduled doses you have logged, up to today, divided by the number due by today, as a percentage.
Supply is vial size times vials on hand, compared with the dose times the doses still to come.
The supply figure counts milligrams only. It does not know that an opened multiple-dose vial is dated when first punctured and discarded within 28 days unless the manufacturer says otherwise,1 so a vial that would last 60 days on paper may need replacing well before then. The cost calculator applies that limit when it counts vials.
Where your data goes
Nowhere. The log is stored in your browser's local storage on this device and is never sent to us or anyone else. That also means it is not backed up: clearing your browser data, switching browsers or using private browsing loses it. The export button saves a copy as text, which is the only way to keep it or move it to another device.
Approved medicines
For an approved medicine, the label's schedule is the one to follow, including what to do after a missed dose, which differs from drug to drug. The GLP-1 titration planner lays out each GLP-1 label's escalation steps and missed-dose rules. The tracker is a notebook; it is not a medical record, and it cannot tell you whether a dose or a schedule is right for you.
