Everything in the app, in one place. Search it, or use the index to jump.
Setting up from scratch, in order.
Go to the Protocols tab and tap + → New. Give it a name (e.g. "Spring Recomp") and a start date. The protocol is the container for everything you're running.
Inside the protocol, add each compound: pick it by name from the library or add a custom one. You enter the dose, units, and reconstitution yourself; Zenject never suggests a dose. Tap the ⓘ next to any section for a full explanation.
For injectables, enter how the vial is mixed: Dry + BAC (powder + bacteriostatic water) or Pre-mixed (a labeled mg/mL solution). This drives the draw calculation.
Enter your target dose and unit. Add a time of day so Today orders doses Morning → Afternoon → Evening. Mark it Fasted or Pre/Post-workout if relevant.
Choose which days of the week each compound is scheduled. Today only shows what's due that day.
Add a titration schedule to step the dose up or down over weeks. Enter blend components for combo vials. Turn on a reminder for a notification at dose time.
Each day, open Today and tap a dose to log it (you'll pick an injection site to rotate). That's your daily practice.
What each of the five tabs is for.
Your daily checklist, grouped Morning / Afternoon / Evening in time order. Tap a dose to log it; tap the ⓘ on a card for full directions, dose, and timing. Tap the date to view another day. The check-in in the practice card (or "Add a check-in" on rest days) opens that day's journal entry.
Pulls weight, body fat %, and BMI from Apple Health and charts them against your protocol periods. Tap a point to inspect it; pinch to zoom.
Browse your daily check-ins: a Mood / Energy / Sleep trend over a feed of every day with a check-in or photo. Tap a card to expand it; use the calendar button or tap the trend to jump to any day.
Create and edit protocols and their compounds. Long-press a protocol to pause it, log past doses, or delete it. Import a protocol shared by a provider, or export your own. The ƒ button opens the reconstitution Calculator.
Log bloodwork as dated draws, with markers from the library or custom ones. Switch to Trends to chart any marker over time, with its reference range and your protocol periods shaded. Import or export panels.
Everything Zenject can do.
Run more than one protocol at once: TRT, Reta, MOTS-C and more, side by side.
Add as many compounds to a protocol as your stack needs.
Step a dose over time, ramping up or tapering down. Today shows which step you're currently on and holds the last dose until the compound or protocol ends.
For combo vials, enter each ingredient's milligrams. Zenject shows the per-ingredient amount in every dose, on the card detail and in the calculator.
When you log a dose, pick the L/R site. Zenject maps your rotation and flags spots you've used too recently.
Set a per-compound reminder time. Multiple compounds due at once combine into one notification. Tap it to jump to Today.
Capture how you feel alongside what you take: mood, energy, and sleep, side effects, a free-form reflection, and photos, all charted as a trend over time. Stored on your device.
Backfill history for a protocol you've already been running, so your earlier doses show up on the Timeline and past Today screens.
Bring in a protocol or lab panel shared as a file or QR code, handy for clinic setup. Everything previews before it saves.
Export your protocols and labs as a file to back up or hand off to a provider.
Optionally sync your data across your own devices through your private iCloud. Your information stays in your iCloud; it's never sent to us.
Reached from the menu — connect Apple Health, notifications, and more.
Tap Connect to let the Timeline read your weight, body fat %, and BMI from Apple Health. It's read-only — Zenject never writes to Health, and the data stays on your device.
Turn on reminders to be notified at dose time (set a per-compound time when editing a compound), and optionally receive a weekly summary each Sunday.
Choose Light, Dark, or Follow System, and toggle the weekly reflection that greets you once a week.
