BPC-157 tracker for iPhone: units to draw, daily shots, cycles and doses left
Tracking BPC-157 means reconstituting a vial, converting a dose in micrograms into units on an insulin syringe, remembering a daily (sometimes twice-daily) shot, rotating sites, running on/off cycles and knowing how many draws are left. Peppy does the units math, counts down to the next shot, suggests the next site on a body map, auto-skips off days in a cycle, and estimates when the vial runs out.
What tracking BPC-157 actually involves
A BPC-157 tracker app has more moving parts than a GLP-1 pen tracker. BPC-157 is a research compound that comes as a lyophilised vial you reconstitute yourself, dosed in micrograms rather than milligrams, on a daily schedule that many people run in on/off cycles. So the questions are: how many units is my dose in this vial, did I do today's shot, where did yesterday's go, is today an off day, and how many draws are left before I need another vial. There is also BPC-157 (Oral), a capsule form, which drops the syringe and the body map entirely.
The math comes first. Enter the mg in the vial, the mL of bacteriostatic water you add, and your dose in mcg, and Peppy's calculator shows "Draw up N units" on a U-100 syringe, warning if the volume will not fit a 1 mL syringe. The calculator is inline in the protocol editor and standalone in the Calculator tab. It is a unit conversion; the dose number is yours. Try it for BPC-157:

| BPC-157 — catalog dose ladder | Dose |
|---|---|
| Step 1 | 250 mcg |
| Step 2 | 500 mcg |
Dose steps as listed in the Peppy catalog so the picker is fast — not a recommendation. Your prescriber sets your dose; Peppy tracks it.
Shot day, rotation and missed doses
A daily shot means sites come around fast. Peppy's body map has 13 sites (four abdomen quadrants, two flanks, two thighs, two upper arms, two glutes, other) and suggests the next one each time you open the log sheet, with "last used 3 days ago" under each. Where you choose to inject is yours to decide with whoever supervises you; Peppy's job is to remember it and not send you back to the same spot tomorrow. If you also run TB-500 or a GLP-1, rotation is shared across all protocols, which is what makes a stack manageable. The injection site rotation guide explains the order and the custom-order option (Pro).
There is no label for a research compound, so there is no missed-dose rule to quote. What Peppy gives you is the fact: the Today tab shows "OVERDUE" with the elapsed time, the Calendar shows the gap, and you log late, skip, or add a past dose. Missed and overdue are computed from your schedule and your log rather than stored, so the calendar never shows duplicates. The missed dose guide is GLP-1 focused but the logging mechanics are the same.
Cycles, twice-daily schedules and inventory
BPC-157 is often run in blocks: 5 days on and 2 off, or a number of weeks on followed by a break. Cycles (Pro) in Peppy take that as an on/off pattern and skip the off days automatically, so reminders stay quiet and the calendar shows the rhythm. If you split the dose into morning and evening shots, set the schedule to twice daily and both appear on the Today list with their own countdowns. The peptide cycle tracker guide covers the presets.
Inventory (Pro) answers the vial question. Enter vials on hand and doses per vial (Peppy suggests it from your reconstitution) and the protocol shows "about 12 doses left, runs out around Oct 3", with a running-low alert and a refill reminder. The vial inventory guide goes into the details.
Side effects and how you feel
The daily check-in is not only for GLP-1 users. Pick the side effects you want to score in Settings: for BPC-157, many people track injection site reaction, bruising and headache, and the feelings list (energy, sleep, mood by default; joint comfort and others available) is often the more useful part. Weight can come from Apple Health if you want it. The Progress tab (Pro) draws a heat-map of your scores lined up with dose days and cycle blocks, which is the only honest way to tell whether a cycle changed anything for you.
What's still active
Peppy's catalog lists a half-life of about 4 hours for injectable BPC-157, an estimate used to draw the "Active in your system" curve. With a short half-life the curve spikes with each shot and falls back within the day, which is why the daily and twice-daily schedules look so different on it. It is an estimate from the catalog half-life, not a measurement, and the oral form carries no curve.

How to do this in Peppy
- Open Protocols, tap + and search "BPC-157". Pick the vial (or BPC-157 (Oral) for capsules). Form, mcg unit and daily frequency are prefilled.
- In the inline calculator, enter the vial's mg, the water you add in mL, and your dose in mcg. Peppy shows the units to draw and stores them.
- Choose Daily or twice daily and set the times. Add a cycle (Pro) such as 5 on / 2 off if you run one.
- Set your last shot date and time so the Today countdown is right.
- Turn on inventory (Pro) with vials on hand and doses per vial for "runs out around" and a refill reminder.
- Turn on dose reminders and the missed-dose nudge in Settings ▸ Reminders (Pro), then pick the side effects and feelings you want in the daily check-in.
Each shot: tap it on Today, tap the suggested site on the body map, confirm the units, log. Free covers one active protocol, the calculator, logging, rotation, calendar, check-ins and iCloud; a second protocol for a stack needs Pro. Peppy is a tracking tool; dose calculations are mathematical conversions only. Always verify with your prescriber.

Is there a BPC-157 tracker app for iPhone?
Yes. Peppy is a free iPhone BPC-157 tracker app. BPC-157 is in the catalog as a daily vial dosed in mcg, with a capsule form listed separately. Enter your vial, water and dose to get the units, set the schedule, and log each shot on a body map.
How do I calculate BPC-157 units?
Enter the vial's mg, the mL of bacteriostatic water you add, and your dose in mcg. Peppy converts it to units on a U-100 syringe and warns if the draw won't fit a 1 mL syringe. The dose itself is yours; Peppy only does the conversion.
Can the app track a 5 on / 2 off BPC-157 cycle?
Yes. Cycles (Pro) take an on/off block such as 5 days on and 2 off, or 4 weeks on and 2 off. Off days are skipped automatically, so the Today tab and reminders stay quiet on them and the calendar shows the pattern.
How many doses are left in my BPC-157 vial?
Inventory (Pro) counts vials times doses per vial, subtracts each logged shot, and shows 'about 12 doses left, runs out around Oct 3' with a running-low alert and a refill reminder.
Does the tracker handle oral BPC-157 capsules?
Yes. BPC-157 (Oral) is a separate catalog entry with a daily capsule schedule. Its log sheet skips the body map and the calculator, and it can run alongside an injectable protocol.
