One File · Powerful peptide tracker
Track it.
Own it. Keep it.
A private, offline peptide tracker in one HTML file. Log doses by time of day, run the syringe-aware calculator, manage your vial inventory, and watch adherence climb — all on your device. No account. No cloud. Buy once.
One payment · Yours forever · 14-day refund
- Works fully offline
- Installs as an app (PWA)
- No account, ever
- Discreet mode + dark mode
The whole tracker loads once, never needs the internet again.
Every dose, every metric, every vial — stored locally. We never see it.
No subscription, no upgrades, no re-up next year. One file, yours.
Why log
Four reasons people who run protocols never wing it.
A peptide tracker isn't admin. It's the difference between a protocol and a vague intention.
What gets tracked, gets honest.
A protocol you carry in your head drifts. A protocol on the page tells you the truth — what you actually took, when, and what you skipped.
Adherence is the variable.
Outcomes hinge less on the peptide and more on whether you took it. The 95% ring is the most useful metric in this app — and it lives on one screen.
Vial maths is unforgiving.
Reconstituted concentration changes per vial. A built-in calculator that knows your syringe is worth a hundred mental rechecks.
This data is private.
Mood, energy, sleep, recovery — and what you took. That belongs on your device, not in someone else's cloud.
Inside the file
Eight things you'll touch every dose. Plus a dozen more.
One file. One dashboard. The whole protocol — adherence, inventory, calculator, library — without a cloud, an account, or a monthly fee.
Time-of-day grouping
Morning, afternoon, evening, before bed — the way you actually dose.
Syringe-aware calculator
Enter mcg or units, see the exact draw on a 0.5ml or 1ml syringe.
Vial inventory
Reconstitution date, mg remaining, expiry — sorted by what's running low.
Reference library
Search peptides, mark favourites, add custom entries. Notes, not prescriptions.
Adherence ring
7d / 30d / 90d / all-time. Streak, perfect days, doses skipped.
Calendar adherence
Month-at-a-glance: 100%, ≥50%, missed, or rest day — colour-coded.
Daily metrics
Mood, energy, sleep, recovery on a 1–10 scale. Patterns, not prescriptions.
Time-of-day mix
Donut + leaderboard showing when and what you actually use most.
Discreet mode
Blur sensitive details with one tap.
Dark mode
Calm UI for late-night logging.
Custom protocols
Build your own schedule, any cadence.
Heads-up alerts
Backup nudges, low-stock warnings.
Day / Week / Month log
Same data, three useful views.
CSV export
Take your history with you, anywhere.

Logging
Log a dose in three taps.
Time of day, peptide, dose. Optional location, state (fasted, fed), and notes. Your full schedule rolls forward automatically — what's done is green, what's pending stays in front of you.
- Morning, afternoon, evening, before bed
- Site (e.g. thigh left), state (fasted, fed), notes
- Mark taken / skipped / edit retroactively
- Day, week, and month log views
Insights
Patterns, not prescriptions.
Adherence ring with 7d / 30d / 90d / all-time views. Day streak, perfect days, total doses. Daily metrics tracked alongside — mood, energy, sleep, recovery — so the whole picture sits on one screen.
- Adherence ring across multiple windows
- Day streak + perfect days + skipped breakdown
- Daily metrics: mood, energy, sleep, recovery
- Time-of-day mix donut + peptide leaderboard
Calculator
The right draw, every single time.
A syringe-aware calculator built for the syringe in your drawer. Pick the barrel, pick the units-per-ml, enter your dose — and see the exact mark to draw to, plus the mcg-per-unit for the current vial.
- 0.5ml and 1ml insulin syringes
- Standard 100 u/ml or custom u/ml
- Visual syringe with the draw marked
- Auto mcg ↔ units ↔ ml conversion
Inventory
Know exactly what's in the fridge.
Each vial: strength, reconstitution date, opened date, storage location, and remaining mg with a progress bar. Sort by expiry so the right vial is always at the top — and get a heads-up when one's running low.
- Vial-level remaining mg with progress bar
- Reconstitution date + opened date tracked
- Storage label (Fridge, Freezer, Room)
- Sort by expiry, low first, name, or recent

The promise
What you take is no one else's business.
Especially not ours.
Local-first by design
Every dose, vial, metric, and note lives in your browser. No server is told. No analytics ping. We literally cannot see your protocol — that's the point.
Discreet by default
A one-tap discreet mode blurs sensitive details on shared screens. Dark mode for late-night logging. No notifications nag the people next to you.
Yours, even if we vanish
Your personalised file works whether OneFileClub exists tomorrow or not. Save the HTML. CSV-export your history. It's a real thing you own.
Data does not sync automatically between phone and desktop
This is a local-first app — everything stays on the device you logged it on. To use it on both phone and desktop, use the built-in JSON or CSV export on one device and import on the other when you want to keep them in step.
Phone
Every screen, in your pocket.
Tap any screen to open it full-size. Swipe or use the arrows to move between them.
Questions
Real answers, no fine print.
Is this a medical or prescription product?+
No. The One File Peptide Tracker is a personal logging tool — like a notebook for your protocol. It does not diagnose, prescribe, or replace medical advice. The library entries are educational placeholders to verify against your own sources. Always consult a qualified clinician for medical decisions.
Where is my peptide data stored?+
Locally, in your browser, on your device. Nothing is sent to OneFileClub or anyone else. There is no account, no email sync, no cloud database. If you clear browser storage the data goes with it — use the built-in CSV export for periodic backups.
Does the tracker work offline?+
Yes. Once your personalised copy loads the first time, the entire app — dashboard, log, calculator, inventory, library — runs from a single HTML file in your browser. Airplane mode is fine. A basement gym is fine. No signal needed.
What does the dose calculator do?+
Pick the syringe you actually use (0.5ml or 1ml insulin syringe), set your reconstitution (e.g. 100 u/ml standard insulin), enter the dose in mcg or units, and the calculator shows the exact draw with a visual syringe marker — plus mcg-per-unit and mcg/ml for the vial.
Can I track vials, expiry, and reconstitution?+
Yes. The inventory view tracks each vial: name, strength, mixed date, opened date, storage location, and remaining mg with a progress bar. Sort by expiry, low first, name, or recent — so the next vial to use is always at the top.
Which peptides does it support?+
Any. The library includes educational reference entries for commonly tracked peptides (BPC-157, Ipamorelin, CJC-1295, Tirzepatide, AOD-9604, 5-Amino-1MQ and many more) and you can add custom entries for anything not listed.
Will my data sync between phone and laptop?+
Not automatically — that is the trade-off for being local-first and private. You can export to CSV on one device and import on the other in seconds. Most people pick one device for logging.
What does 'personalised copy' mean for this tracker?+
When you buy, OneFileClub stamps a private copy of the tracker with your licence and deploys it to a unique URL just for you. We email the link, you bookmark it or install it as an app — and the file is yours, even if OneFileClub disappears tomorrow.
What is your refund policy?+
14 days, no questions asked. Email us with your order ID, we will process the refund and disable your private URL.
Track it. Own it.
Keep it.
We'll personalise a copy and email you a private link, usually within a minute. Bookmark it, install it as an app, save the file. Yours.
