The reason spreadsheets fail at this is not discipline. It is that a spreadsheet cannot compute, has no sense of time and has no model of where an injection went — so the reconstitution arithmetic gets redone from memory, nothing notices a missed day, and the site column becomes fiction nobody reads back.
Pep AI closes those three gaps directly. Reconstitution is calculated from the vial, the schedule reminds you and notices gaps, and sites rotate on a real model of the body rather than a text field.
What makes a record worth keeping is whether it can answer a question you had not thought to ask when you started it — what was different about the period this worked, how long the last gap actually was, whether you have been favouring one region without noticing. That takes the context, not just the dates.
Everything a protocol needs, in one place
The parts people fail to record are the parts that make a record useful.
Context with every dose
Which vial, which site, what you noticed — recorded alongside the dose, because a date and an amount alone answers nothing later.
Doses & schedules
Daily, every-other-day, or fully custom. Get a reminder when it's time, log it in one tap, and your history builds itself.
Vials & reconstitution
Enter your vial and bacteriostatic water and Pep AI converts your dose into exact syringe units — no mixing math, no guessing.
Injection sites
Automatic site rotation so you always know where the last shot went and where the next one should go.
Estimated levels
See your estimated compound level rise and fall between doses, modelled from your schedule and published half-lives.

Frequently asked questions
What should I be recording in a peptide protocol?+
Reconstitution details per vial, each administration with date and time, the injection site, the vial's state, your observations, and what else changed at the same time. The first is the most commonly omitted and the most damaging to miss — without it, no unit figure means anything later.
Why not just use a spreadsheet?+
A spreadsheet cannot do the reconstitution arithmetic, has no sense of time so nothing reminds you or notices a gap, and has no model of injection sites so rotation becomes guesswork. Each gap adds friction at the moment of logging, which is what erodes the habit.
Does Pep AI give medical advice?+
No. Pep AI is a tracking and organisation tool, not a medical device. It does not recommend compounds, doses or schedules, and Pep Bot declines dosing questions. What to take stays between you and a qualified clinician.
