BPC-157 Tracker App

By Tessaro Pty Ltd, the maker of Pepti · Reviewed October 2026

BPC-157 is an investigational research peptide. No regulator has approved it for any use, and published reviews describe human data as extremely limited — the evidence, and why no reliable human half-life exists, is set out on our BPC-157 reference page and in the sources listed below. This page is about the record rather than the compound. It is written by the maker of Pepti, so read the Pepti-specific parts as a description of our own app.

How a BPC-157 log differs from a weekly one

The weekly GLP-1s have an approved label that sets the cadence. BPC-157 has no label anywhere, so there is no standard schedule to point to: the cadence is whatever you and whoever directs your use have settled on. A weekly routine produces about fifty entries a year; if your schedule is daily, a BPC-157 log produces that many in under two months. More entries mean more sites used, vials emptied sooner, and more chances for a gap or a duplicate to slip in.

A Pepti schedule can be daily, every other day, two or three times a week, or weekly, on the weekdays you pick, and it can run in on and off cycles if that is how your routine is structured — how to track peptide cycles covers that method. Reminders follow the schedule and repeat your own figure; they never supply one.

Setting up a BPC-157 vial

BPC-157 is commonly supplied as a lyophilized, or freeze-dried, powder, though some material is sold already in solution, as the reference page notes. For a powder, you record the peptide in the vial, the water you add and the date you mix it; for material that arrives in solution, you enter the label strength instead. The app does not do the reconstitution arithmetic; the free reconstitution calculator on this site does.

Then fill in the fields that identify the vial: the vendor, the batch or lot number, where it is stored, what it cost, the expiry stated on it, and the date you mixed it. A 2026 review lists BPC-157 among unapproved injectable peptides that lack an established human safety profile (Moiz et al., Missouri Medicine 2026), and if anything about a batch is ever in question, the vendor and lot number are the only way to see which entries it touched.

What to log for each injection

Rotation when injections are frequent

At a weekly cadence, rotation is a memory problem stretched over months. At a frequent one the sites come round fast, and the risk is landing in the same place on consecutive days. Pepti uses twelve sites — abdomen, thigh, deltoid, glute, love handle and tricep, each left and right — and a daily schedule uses all twelve within two weeks. When you log, the app looks at your recent injections and suggests the least-used site, on the opposite side from the last, so consecutive injections land apart without planning. Its site view shows whether one area is being favoured. The injection site rotation guide explains the scheme.

Vial age and cost

Once a powder is mixed, the clock that matters is the vial’s age. As the reference page notes, limits after mixing differ by product, and the instruction that governs your vial is whatever its source specifies; this page supplies no figure for it. Pepti records the date you mixed the vial and the expiry you entered, and warns as that expiry approaches, so the age of a vial is never a guess.

The vial also has an age. Pepti keeps the date you mixed it and the expiry or use-by date you enter, and warns as that date approaches. You can record what the vial cost too; the app keeps the price you typed and does not work out a cost per injection or how much is left.

Why there is no half-life figure for BPC-157

For the weekly GLP-1s there is a published label half-life. For BPC-157 there is not. No reliable human half-life has been published: the evidence base is preclinical, and reviews describe human data as extremely limited (McGuire et al., 2025; Józwiak et al., 2025). A figure circulating online as its human half-life is not drawn from a human study, and a curve built on it would look precise and mean nothing. The app does not chart levels, and the half-life decay calculator on this site only plots a value you type in; for this compound there is no sound human value to enter. What you can rely on honestly is the dated history itself.

Weight and other trends

Weight is central to a GLP-1 record; for BPC-157 it may or may not be relevant to why you are logging. Pepti keeps weight on the same timeline if you record it, and the record works just as well without it. What matters more is consistency: observations recorded the same way each time — the same wording, photos under the same conditions — become a line you can read across weeks. The app shows what you recorded next to when you injected; it does not interpret it, and it makes no claim about what BPC-157 does.

Privacy: no account, on-device

A research-peptide log is a private record, and most trackers store theirs on a company server behind an account. Pepti has no account and no sign-up, and the log, vial records, notes and photos stay on your iPhone. There is no cloud sync. That data leaves your phone only if you turn on the AI coach or lab-report import, both behind one consent switch, and then only your coach messages with the app context they need, or the report you import, are sent to Pepti’s server and processed by Anthropic.

Is Pepti the right BPC-157 tracker for you?

Pepti is built for drawing from vials on an iPhone, so the vial records, the link from each injection to its vial and fast-moving rotation are its core. It is iOS only, on iOS 17.2 or later; pricing is in the questions below. Prefer no app? The free peptide tracker spreadsheet holds the core fields. Our tracker comparison covers the wider field, the peptide tracking app guide covers what any tracker should do, and the compound reference index lists every compound we cover.

Common questions

What is a BPC-157 tracker app?

A BPC-157 tracker app is a record-keeping tool for a vial-based research-peptide routine. It stores the date, time and site of each injection, the vial it came from with its batch and mixing date, and what you observed, so the history lives in one place. Pepti also keeps each vial's expiry and use-by dates. It never decides anything medical for you.

Does Pepti do the reconstitution math for a BPC-157 vial?

No. The app records the peptide in the vial, the water you add and the date you mix it, and links each injection to that vial, but it does not calculate a concentration, a draw volume or syringe units. The free reconstitution calculator on this site does that arithmetic. You supply the figure; the app only records it.

Can I track a daily or cycled BPC-157 schedule?

Yes. A schedule in Pepti can be daily, every other day, two or three times a week, or weekly, on the weekdays you choose, and it can run in on and off cycles. Reminders follow it and show the figure you entered. The schedule is yours; Pepti does not suggest one.

Is BPC-157 approved?

No. BPC-157 has not been approved by the FDA or any other regulator for any use, and published reviews describe it as investigational, with extremely limited human data. Pepti can log it, but logging it is not an endorsement.

Does Pepti tell me what dose of BPC-157 to take?

No. Pepti supplies no dose figures for BPC-157 or anything else, and this page contains none. It records the figure you already have from whoever directs your use, with the date, time, injection site and vial. The record is ours to keep; the figure is not.

Is my BPC-157 data private?

There is no account and no sign-up, and your log, vial records, notes and photos stay on your iPhone. There is no cloud sync. That data leaves your phone only if you turn on the AI coach or lab-report import, both behind one consent switch, and then only your coach messages with the app context they need, or the report you import, are sent to Pepti's server and processed by Anthropic.

How much does Pepti cost?

Pepti is $12.99 per month or $49.99 per year in USD, with no free trial; you can cancel anytime. There is one tier and no free version: every feature is included, with nothing gated behind an upgrade, and there are no ads in the app. Your protocol and health logs are not used for advertising; install attribution uses Apple's tracking permission prompt.

Is there a free BPC-157 tracker option?

Pepti is paid, at $12.99 per month or $49.99 per year in USD with no free trial. If you want a free route, the peptide tracker spreadsheet on this site is a plain template with the core fields, and the reconstitution calculator is free to use in a browser. Neither needs an account.

Can I track BPC-157 and TB-500 in the same log?

Yes. Pepti logs each compound separately, with its own schedule and its own vial, on one timeline and one site rotation. It records what you enter for each; it does not suggest combining compounds or how to.

If you draw BPC-157 from vials on an iPhone and want the vial records, the rotation and the vial history in one private record, Pepti is built for that. If you are on Android, or would rather keep a spreadsheet, the links above will point you somewhere that fits.

This page describes record-keeping. It does not recommend BPC-157 or any other substance, and it provides no dose figure and no schedule. BPC-157 is an unapproved research peptide and is not approved for any use.

Not medical advice. Pepti is a record-keeping tool, not a medical device.
