See what's due, what's next, and what needs attention — the moment you open the app.

Every day logged

Consistency, made visible.

Peptide Protocol check-in history with completed days from Saturday May 2 back through Monday Apr 27 — energy and sleep logged daily

A calm history that rewards the work — recent check-ins, completed days, and the patterns building over time.

In the vial

The math, before the draw.

Vial strength, bacteriostatic water, target dose — resolved into exact units on the syringe in your hand, before you pull anything back.

What's working

Trends that actually mean something.

Adherence, weight, energy, appetite, sleep — charted so you can see what's working over weeks and months.

Never double up

Smart injection site rotation.

Get started

How to track a peptide protocol on iPhone — in four steps.

  1. Build your protocol

    Add your peptide(s), set the dose and reconstitution details, and choose a cadence — daily, weekly, or custom.

  2. Set your schedule

    Pick the time you'll dose and the app sends a gentle iOS reminder. The next injection site is suggested automatically based on your rotation map.

  3. Log your dose and check-in

    Tap Done when you dose. Optionally log a daily check-in for energy, sleep, appetite and weight to surface patterns over weeks.

  4. Review your insights

    The Insights tab charts weight, adherence, side effects and progress. Export the report when you check in with a clinician.

Frequently asked

Questions, answered.

Is Peptide Protocol free?

Yes. Peptide Protocol is free to download on the iPhone App Store. There is no account requirement to use the core tracking features.

Does Peptide Protocol work without an internet connection?

Yes. The app is built to work offline. Your protocol data, logs, schedules, and reconstitution calculations all live on your iPhone. No account, no cloud sync, no leak.

Which peptides does Peptide Protocol support?

The app supports any peptide protocol you build. The included reconstitution calculator has presets for 40+ common peptides including Tirzepatide, Semaglutide, BPC-157, TB-500, CJC-1295, Ipamorelin, Tesamorelin, GHK-Cu, HGH, and more.

Does the app include a reconstitution calculator?

Yes. The built-in calculator converts vial mg, bacteriostatic water volume, and target dose into exact units on a U-100, U-50, or U-30 insulin syringe. A free web version is also available at peptide-calc.app.

Can Peptide Protocol track multiple peptides at once?

Yes. You can run multiple protocols and stacks side by side, each with its own dosing cadence, schedule, and inventory. The Today screen shows everything due across all active protocols.

Does Peptide Protocol remind you to dose?

Yes. The app sends gentle iOS notifications at your scheduled dose times. You can also pin a home-screen widget that shows your next dose, current streak, and the next injection site at a glance.

Does Peptide Protocol manage injection-site rotation?

Yes. A body-map shows which sites are ready, which are in cooldown, and which is up next, so you never double up on a site that needs more time to recover.

Is Peptide Protocol medical advice?

No. Peptide Protocol is a personal tracking tool. Nothing in the app constitutes medical advice. Many peptides are prescription-only or restricted in your jurisdiction. Always consult a licensed healthcare professional before injecting any compound.

Does Peptide Protocol sync with Apple Health?

Yes. Peptide Protocol can write your weight, body measurements, and check-in vitals into Apple Health, and read weight back so your charts stay in sync. Sync is opt-in — you choose which Health categories to share, and you can revoke access at any time in iOS Settings → Privacy & Security → Health.

Can I export my logs and protocol history?

Yes. From Settings → Export you can download a CSV of your dose log, check-ins, weight history, and inventory — useful for sharing with a clinician or backing up before changing devices. A JSON export is also available for full restore.

How does the injection-site rotation cooldown work?

Each site (left/right deltoid, abdomen quadrants, thigh, glute) has a configurable cooldown — typically 48–72 hours. After you log a dose, that site is marked in-cooldown until enough time has passed for tissue to recover. The Today screen always shows the next site that's ready.

Is Peptide Protocol HIPAA compliant?

HIPAA applies to Covered Entities (clinicians, insurers) and their Business Associates — not to a personal tracking app you use for yourself. Peptide Protocol stores your data on-device by default and does not transmit it to any server, so your protocol history never enters a HIPAA-relevant data flow in the first place.

Do I need a prescription to use Peptide Protocol?

No. The app is a tracking tool — it doesn't require, recommend, or prescribe any compound. Many peptides are prescription-only or restricted in your jurisdiction; that's a question for a licensed healthcare professional, not the app.

Which insulin-syringe sizes does the calculator support?

The reconstitution calculator supports U-100, U-50, and U-30 insulin syringes, plus standard mL syringes. Toggle the syringe type and the calculator instantly recomputes the exact units to draw.

Is Peptide Protocol better than tracking peptides in a spreadsheet?

Spreadsheets handle the math but miss the rest — they don't remind you when a dose is due, they don't track which injection site is in cooldown, they don't aggregate side-effect patterns over weeks, and they don't restore from a fresh device. Peptide Protocol does all of that, and the reconstitution math, in a single iPhone app you'd actually open every day.

Philosophy

Protocols don't fail from complexity — they fail from friction: a missed dose, a confused rotation, a number you forgot to log. This removes the friction.

What Peptide Protocol is — and isn't

It is a personal tracking tool. It does not diagnose, prescribe, or replace a clinician. Many peptides are prescription-only or restricted in your jurisdiction — always consult a licensed healthcare professional before injecting any compound.

About Peptide Protocol

Built by a small team that uses peptide protocols too.

We're a small independent team. The app was built first for our own routines, then opened up. There's no investor pressure to push subscriptions, no telehealth back-end selling compounds, no upsell to a clinic.

Our editorial standards, medical-review process, and corrections policy live on our sister site at peptide-calc.app/editorial-policy. Reference content is sourced from primary literature and reviewed before publication.
