Your rotation, your device, your business. Log what went where and keep every site fresh.

Tick a site to leave it out of the suggested rotation. Ticked sites never come up as the suggestion, but you can still tap them on the body map if you ever want one deliberately. Saves and syncs like everything else.
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.
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.
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.
The reverse: you know the vial and how much you want per injection, and it tells you how much bacteriostatic water to add.
Add a dated weight entry. Your entries stay local with the rest of the tracker.
Log waist, chest, arms, thighs, hips or neck on any date. Everything stays local with the rest of the tracker.
Blood pressure and resting heart rate on any date. This is a personal log only — it doesn't interpret or flag your numbers.
Log any lab result by name — cholesterol, glucose, hormone panels, whatever you get tested. Free-form, since panels vary a lot person to person.
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.
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.
Set each compound's dose and rhythm once. Logging stays in the Rotation Log. The schedule just tells you whats due.
Instead of auto-suggesting the least-used site, follow a fixed sequence — useful if your rotation is prescribed, like quads → left ab → right ab. Excluded sites stay out either way.
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.
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.
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.
Injection site rotation is the difference between a month of clean pins and a wall of scar tissue. Most people start out rotating by rote — "one cm this way today" — and a few months in they realise they've been hammering the same four spots on autopilot. This tracker fixes the one thing memory can't: it remembers. Tap where you pinned on the front-and-back body map, and it suggests the site that's gone longest without use. You can ban areas entirely, follow a saved rotation order, and keep your whole history in your own browser.
Add your vial's total mg, how much bacteriostatic water you reconstitute with, and your dose — the built-in reconstitution calculator tells you the concentration (mg and mcg per ml) and exactly how much to draw, in ml and IU on a U-100 pin. It also handles weekly-target dosing: enter a weekly total and how often you pin, and it works out the per-pin amount. Works for any compound — TRT enanthate/cypionate, GHRP, ipamorelin, whatever you're mixing.
