Peptide Tracker — User Guide

A clear walkthrough of Protocols, Logs, Inventory, Reminders, and the Converter

Important disclaimer

Not medical advice. This Peptide Tracker is an organizational tool only. It does not provide medical guidance, dosing recommendations, or treatment decisions. Always follow the advice of a licensed healthcare professional for any medication, peptide, supplement, or injection routine.
Use at your own risk. You are responsible for the accuracy of any entries (dose, units, timing, and concentration). Double‑check calculations and labels before administering anything.
Data/storage notice. Your data is stored locally in your browser (localStorage). Clearing site data, using private mode, or switching devices/browsers can remove access to your logs and inventory.

Quick start

If you only read one section, read this. You’ll be tracking in under a minute.

  1. Create a Protocol

    Go to Tracker → Protocols and add your protocol (name, dose, route, schedule).

  2. Log a dose

    Tap Log now on the protocol card. This creates a log entry and (optionally) updates Inventory.

  3. (Optional) Link Inventory

    If you track stock, create an Inventory item and link it to the protocol so Remaining decreases automatically on each log.

  4. Use Reminders

    Open Reminders to see what’s next due, Snooze, or download a calendar event.

Where your data lives: This app stores data locally in your browser (localStorage). If you clear site data or switch devices/browsers, the data won’t follow automatically.

App tabs (what each one is for)

Tab Use it for Most common actions
Tracker Create and manage Protocols, view Protocol Notes, and log doses. Add protocol, edit protocol details, log now, view next due
Inventory Track stock per vial/pen/bottle (Total, Remaining, Used) and low warnings. Add item, update Remaining, link to protocol, delete item
Converter Quick conversions (e.g., mg ↔ mL, IU math if you use it). Enter values, copy results
Reminders See each protocol’s Next due, Snooze, and export a calendar event (.ics). Snooze 1d/2d, download .ics
Protocol = your plan Log = what you actually did Inventory = what you have left Reminder = when to do it next

Protocols

A Protocol describes what you intend to take and how often. Think of it as a reusable template for logging.

Fields you’ll see

  • Name: what you’re tracking (e.g., “BPC-157”).
  • Dose: default amount to log (e.g., 2.5 mg).
  • Route: how you take it (e.g., subq, IM, oral).
  • Schedule / Frequency: used to compute Next due for Reminders.
  • Protocol notes: anything you want (timing, injection site, reconstitution ratio, etc.).
  • Inventory link (optional): connects the protocol to an inventory item for auto-deduction.
Tip: Keep dose units consistent per protocol (e.g., always mg). This makes Inventory deduction and the Converter much smoother.

Common actions

  • Edit: update dose/schedule/notes without creating a log.
  • Log now: creates a new log entry using the protocol’s defaults.
  • Delete: removes the protocol. If it has logs, those logs are removed too (and Inventory is restored accordingly if deductions were recorded).

Logging doses

Logs are your history. They store date/time and what you took. Logs can also carry an “inventory deduction marker” so edits/deletes can be reconciled correctly.

Log now

  • Tap Log now from a protocol card.
  • The app creates a log entry with timestamp + dose.
  • If auto-deduct is enabled and the protocol is linked, it subtracts from Inventory Remaining.

Edit a log (and Inventory)

When you edit a log dose, Inventory adjusts automatically:

  • The app adds back the previously deducted amount (if any).
  • Then it deducts the new amount.

Delete a log (and Inventory)

When you delete a log entry, any recorded inventory deduction is reversed (Remaining increases).

Why this matters: Without automatic reconcile, inventory “drifts” when you edit historical logs. The tracker is set up to keep Remaining accurate even when you clean up past entries.

Inventory

Inventory tracks stock per item (for example, one vial). It’s designed to be simple, but accurate.

Total vs Remaining

  • Total amount: the baseline quantity for the item (e.g., the vial contains 10 mg total).
  • Remaining: how much is left right now (this is what changes when you log doses).
  • Used: automatically calculated as Total − Remaining (and a % used).
Validation: Remaining can’t exceed Total. If you enter a higher number, the app clamps Remaining down to Total.

LOW warning

If Remaining is at or below 20% of Total, the item is flagged LOW.

Linking Inventory to a Protocol

  1. Create an inventory item

    In Inventory, add Total and Remaining (usually the same initially).

  2. Link from the Protocol

    In the Protocol editor, choose that inventory item for auto-deduction.

  3. Log doses normally

    Each log will subtract from Remaining, and edits/deletes will reconcile automatically.

Important: For very old logs created before reconciliation was added, the app may not know what inventory item was deducted. New logs always store a deduction marker for reliable adjustments.

Reminders

Reminders show Next due per protocol based on your schedule and last logged dose.

Next due

  • If you have logs, Next due is computed from the most recent log + the protocol’s interval.
  • If you have no logs, Next due uses your protocol schedule starting point (as configured).

Snooze buttons

Each protocol has big buttons:

  • Snooze 1 day: pushes Next due forward 24 hours (without changing your protocol settings).
  • Snooze 2 days: pushes Next due forward 48 hours.

Calendar export (.ics)

Tap Download .ics to create a one-time calendar event for the next dose. This is useful when you want it on your phone’s calendar without any push-notification system.

Tip: If you change your schedule, Reminders update immediately. If something looks off, check your protocol interval and your last log timestamp.

Converter

The Converter is for quick math when you need it. Typical uses:

  • Convert a dose from mg to mL based on your concentration.
  • Convert between units you use regularly (e.g., IU workflows).
  • Double-check “how much to draw” before logging.
Safety note: Always verify medical dosing with a qualified clinician. This tracker is for personal organization, not medical advice.

Dark mode & Help

  • Use the sun/moon icon next to the title to toggle Light/Dark mode.
  • The ? icon opens the Help panel.
  • Help content is styled for readability in dark mode (no “invisible text”).
Display tip: If you’re on iPhone, dark mode will look best with “Increase Contrast” off and brightness around 40–70%.

Tips & best practices

  • Use consistent units per protocol (mg is simplest).
  • Don’t retro-edit casually: edits are supported, but frequent backdating can confuse “Next due.”
  • Inventory accuracy: if you manually restock, update both Total (if it represents capacity) and Remaining appropriately.
  • Keep protocol notes useful: include dilution ratio, injection sites, timing rules, or clinician guidance.
  • Backup mindset: if you rely on this daily, consider periodically saving a copy and/or screenshots of key history.

FAQ

Why is my Reminders tab empty?

You’ll only see reminders when you have at least one Protocol. Create a protocol in Tracker first.

Why does Inventory “Used” show a dash?

Used is calculated only when both Total and Remaining are valid numbers. If either is blank, it displays —.

What happens if I delete a log or protocol?

The app reverses any recorded inventory deduction for those logs, so Remaining stays accurate.

Can I use this on multiple devices?

Not automatically. Data is stored locally in your browser. If you want multi-device sync, you’d need an export/import feature or a backend (not included by default).
