PeptideGenius is free and stays free. If it's saved you time, money, or a missed dose, a small tip keeps the updates coming — and lets me spend weekends on new features instead of on rent.

Important disclaimer

PeptideGenius is a personal tracking tool, not medical advice, diagnosis, or treatment. Peptides are research compounds in most jurisdictions and are not FDA-approved for human use outside specific prescription contexts. Always consult a qualified healthcare professional before starting, changing, or stopping any protocol. You are solely responsible for your own choices, sourcing, sterility, and injection technique.

The Reconstitution Calculator does arithmetic — it cannot verify that your vial is what the label says, that your BAC water is sterile, or that your intended dose is safe for you. The Rotation Map is an educational aid, not a substitute for proper injection training. Verify every calculation and technique with a licensed clinician.

Frequently Asked
Questions & answers
Privacy & Data
Do you store any of my data on a server?
No. PeptideGenius is a single HTML file that runs entirely in your browser. Every shot, schedule, and note stays in your browser's local storage on your device. There is no account, no sign-up, and no cloud sync.
Do you use analytics, cookies, or trackers?
None. No Google Analytics, no pixels, no third-party scripts, no ads. Open the page source and search — you won't find any.
Can other people see what peptides I'm using?
Only if they have physical access to your device and browser profile. Nothing is ever transmitted off your device by this app.
Backups & Moving Devices
Where are the Save backup and Import buttons?
They're hidden behind a deliberate gesture to prevent accidental taps. Tap the PeptideGenius syringe logo at the top-left of the app three times in quick succession (within about a second). The Save backup and Import buttons will appear right next to the logo. Tap the logo again (single tap) or load a file to hide them. This keeps casual pokes from triggering a file download while still making the controls easy to reach when you want them.
Why might my data disappear?
Browsers tie saved data to the exact file path and origin. If you download a newer copy of the HTML file (e.g. peptide_tracker (2).html), the browser treats it as a different site and you'll see an empty tracker. Use Save backup regularly, or deploy the file to a stable URL like peptidegenius.net.
How do I back up my data?
Triple-tap the PeptideGenius logo at the top-left of the app to reveal the hidden controls, then click Save backup. This downloads a JSON file containing all of your shots, stacks, inventory, and settings. Keep a copy somewhere safe (cloud drive, USB, email to yourself).
How do I restore or move to a new device?
Open the app on the new device, triple-tap the logo to reveal the hidden controls, then click Import and select your JSON backup. Everything will come across — shots, schedules, inventory, prices, and package tracking.
How often should I back up?
After any significant change (new stack, new inventory, dose adjustment), and at minimum once a week. The backup file is tiny — usually under 100 KB.
Install as App
How do I install PeptideGenius on my iPhone or iPad?
iOS Safari doesn't show an automatic install button, so you add it manually:

1. Open the app in Safari (not Chrome on iOS — only Safari can install a PWA).
2. Tap the Share icon at the bottom of the screen — the square with an arrow pointing up.
3. Scroll down in the share sheet and tap Add to Home Screen.
4. Tap Add in the top-right.

The PeptideGenius icon now lives on your home screen and opens full-screen like a native app.
How do I install on Android?
Option A: When the Install this app banner appears at the top of the page, tap Install. The browser may also show an "Install" chip in the address bar — tap that.

Option B (if no banner): In Chrome, tap the three-dot menu (⋮) in the top-right corner, then tap Install app or Add to Home screen. Confirm when prompted.

Works in Chrome, Edge, Samsung Internet, and Brave. Firefox on Android supports home-screen installation via the page-info menu but with fewer PWA features.
How do I install on desktop (Mac, Windows, Linux)?
In Chrome or Edge, look for an install icon in the address bar (a small monitor with a downward arrow, or a "+" icon). Click it and confirm. You can also use the three-dot menu → Install PeptideGenius. Installed desktop PWAs run in their own window and show up in your OS's app list.

Safari on macOS supports adding pages to the Dock via File → Add to Dock (macOS Sonoma and later).
Why don't I see the "Install this app" banner?
A few possible reasons:

You're on iOS Safari — the banner uses a browser event Apple doesn't fire. Use Share → Add to Home Screen instead (see above).
You already installed it — the banner hides once the app is in standalone mode.
You dismissed it recently — it stays hidden for 14 days after dismissal.
Chrome hasn't decided it's installable yet — the browser waits for a short period of "engagement" (usually a few seconds of real use) before offering installation. Click around the app a bit and come back.
Browser doesn't support it — older browsers or unusual setups may not fire the install event.
What happens to my data when I install?
Nothing changes. Your data lives in your browser's local storage under the domain you're visiting. Installing as an app doesn't move, copy, or duplicate it — the installed app and the browser tab share the same storage. If you later uninstall, the data remains accessible from the browser. If you clear browser data for that site, both copies lose it. Always keep a backup.
Will it work offline once installed?
Yes, when the host provides the companion service worker (sw.js). In that setup, the browser caches the HTML, icons, and assets, so the app opens instantly with or without a connection. Package tracking and any future network-dependent features still need internet — but logging shots, checking schedules, running the calculator, etc. all work offline.

If you're opening a downloaded HTML file directly (file://) rather than a hosted URL, service workers don't run — but the browser caches the file anyway, so it still works offline in practice.
How do I get updates to the app?
When the app is hosted on a server with the service worker active, updates arrive automatically — next time you open the app, the browser fetches the latest version in the background. Your data is untouched by updates.

If you downloaded the HTML file directly, download the new version and Save backup from the old copy first, then open the new HTML and Import the backup.
Features
What peptides does the app support?
Any peptide — the app is not limited to a fixed list. Add whatever you're running (BPC-157, TB-500, Semaglutide, Tirzepatide, Retatrutide, GHK-Cu, Ipamorelin, CJC-1295, Tesamorelin, MOTS-c, Epithalon, Semax, Selank, KPV, SS-31, and more). The Titration page also includes reference protocols for common compounds.
Does the Reconstitution Calculator handle insulin syringes?
Yes. You can enter volume in mL or in insulin-syringe "units" (1 unit = 0.01 mL on a U-100 syringe). The calculator converts automatically.
Can I track peptides I take orally or as a nasal spray?
Yes. When editing a dose, choose pill as the unit, or just log it as a normal entry and note the route in the notes field.
How does package tracking work?
Enter a carrier and tracking number in the Package Track tab, and the app fetches public tracking status from the carrier. No account needed.
General
What's the difference between free and Pro?
Free tier: Perfect for getting started. 3 active peptides, 5 vials, 90 days of shot history, basic tracking, install as app.

Pro tier ($5/mo, $49/yr, $79 lifetime): Unlimited peptides and vials, full shot history, supply forecasting, advanced analytics, cloud backup + sync, data export (JSON/CSV), priority support.

No ads. No sketchy payment stuff. Cancel anytime. Start free, upgrade only if you need it.
Can I install it as a phone app?
Yes — PeptideGenius is a PWA. See the Install as App section above for step-by-step instructions for iPhone, Android, and desktop.
Is this medical advice?
No. PeptideGenius is a personal tracking tool. Peptides are research compounds in most jurisdictions. Always consult a qualified healthcare professional before starting, changing, or stopping any protocol.
