Log an injection

Each save creates a separate entry. Multiple entries can use the same date, including multiple different compounds on the same day.

Supplies & stock

Track what's left in each vial, pen, or bottle — including bacteriostatic water for reconstitution — and get a rough reorder date. Put the same compound in twice and it reads as one pool. If a vial is mixed (like 10mg in 1ml of water), enter the compound amount in mg and the water in ml — then logging a dose in either mg or ml deducts the right amount. Logging an injection auto-deducts from a matching compound; use "Log a use" for everything else. Stock never blocks or changes an entry — it's a ledger, not a gatekeeper.

Reconstitution & draw calculator

Works off the pools above. A standard U-100 insulin pin holds 1 ml, so 100 units on the pin = 1 ml of mixed peptide.

Peptide dose calculator

No stock or account needed — pick your vial, your water, and your dose, and it gives the concentration and exactly what to draw. Standard U-100 insulin pin: 100 units = 1 ml.

Bac water calculator

The reverse: you know the vial and how much you want per injection, and it tells you how much bacteriostatic water to add.

Weight check-in

Add a dated weight entry. Your entries stay local with the rest of the tracker.

Body measurements

Log waist, chest, arms, thighs, hips or neck on any date. Everything stays local with the rest of the tracker.

Recent measurements

Vitals check-in

Blood pressure and resting heart rate on any date. This is a personal log only — it doesn't interpret or flag your numbers.

Recent check-ins

Lab markers

Log any lab result by name — cholesterol, glucose, hormone panels, whatever you get tested. Free-form, since panels vary a lot person to person.

Build My Workout Plan

Answer a few questions and this generates a phased 12-week program: weeks 1–4 build volume, 5–8 add load, 9–11 intensify, and week 12 is a deload/assessment week — the same structure IronPhase used, but built from your own settings instead of one fixed routine.

Build a Meal Plan

Set a daily calorie target and exclude anything you don't eat — the plan only pulls from what's left. This is a practical planning tool, not dietary or medical advice; it doesn't know your individual nutritional needs.

Add to schedule

Set each compound's dose and rhythm once. Logging stays in the Rotation Log. The schedule just tells you whats due.

Backup status

Your local tracker data is ready to back up.

Backup & move to another device

Your log stays in this browser. To move it to another browser or device without putting your entries on an app server, use an encrypted backup. The backup is encrypted in your browser and you control the file and passphrase.

Local browser storage • no app database

Cloud sync (optional — you opt in)

Off by default — everything above still works purely locally, and nothing here is sent anywhere unless you fill this in and press one of the buttons below. There's no site-wide password and no visitor accounts: your email and passphrase are combined and hashed in your browser into a unique key, and that key — never your email or passphrase themselves — is what's sent to identify which stored copy is yours. Anyone syncing needs to supply the exact same email + passphrase to reach that same copy again, so treat the passphrase like a password: if you lose it, that data isn't recoverable, and the site owner has no way to reset it for you.

Not synced yet.
Auto-sync Off

With auto-sync on, this device pulls the cloud copy when the app opens, while it's open, and whenever you come back to the tab, and pushes your changes a few seconds after you make them. To work unattended it keeps your email and passphrase in this browser's local storage, so don't enable it on a shared device.
