Peptide Tracker Calculator

PeptideCalc.io is a private peptide, GLP-1, TRT, and medication protocol tracker with calculators for user-entered reconstitution values, syringe units, schedules, reminders, dose logs, inventory tracking, insights, exports, and optional iCloud sync.

CALCULATORS & TRACKING
• Reconstitution calculator for custom vial values you enter
• Syringe-unit and concentration tools for custom vials, premixed vials, injector pens, oral meds, liquid meds, and IU workflows
• Multi-compound support with proportional unit conversions
• Reference presets for common GLP-1, TRT, hormone, peptide, and supplement workflows
• Common syringe formats including U-100, U-50, U-40, U-30, and 1-5 mL Luer-Lock options
• Visual syringe guide based on your entered vial, concentration, and amount values
• Save protocols and reuse your own entered details

PROTOCOLS & SCHEDULES
• Save, duplicate, favorite, search, and sort protocols and schedules
• Inline edits with instant updates
• Create schedules from saved protocols with start and end dates
• Multiple times per day with flexible cadences: daily, weekdays, every N days/weeks, monthly, or cycling windows
• Titration planning tools for schedules you define
• Multiple schedules per protocol, color-coded and sortable
• Dose reminders with optional time-sensitive notifications

CALENDAR, LOGGING & INVENTORY
• Calendar view plus pending doses list
• Log scheduled or as-needed doses with injection site, method, notes, and timestamps
• Custom injection sites with last-used hints
• Mark doses done, missed, or skipped
• Adherence metrics, streaks, and protocol filters
• Track vials, pens, pills, liquids, and syringe supplies
• Runout estimates and low-stock alerts based on your schedules or logs

INSIGHTS
• Biometrics dashboard for weight, body composition, sleep, heart rate, blood pressure, glucose, labs, mood, energy, hunger, libido, recovery, and custom metrics
• Manual entries and optional Apple Health import
• Trend charts with 7/30/90/180/365-day views
• Dose overlay charts for comparing your logged doses, schedule changes, and biometric trends
• Half-life and medication-level charts based on your saved protocol data
• Protocol filters and summaries to compare trends over time

BACKUP, SYNC & SHARING
• Optional iCloud sync across devices
• Automatic local backups with restore points
• Import backups for protocols, schedules, logs, injection sites, inventory, and insights data
• Export protocols, schedules, logs, and dose history to JSON, CSV, or PDF

PERSONALIZE
• Dark, light, system, or many custom themes
• Locale-aware decimal input and haptic feedback
• Celebration effects for consistency milestones
• Use offline without an account; iCloud sync optional

PRIVACY

Important: PeptideCalc.io is an informational utility only. It does not diagnose conditions, prescribe treatment, recommend medications, recommend dosages, choose schedules, or determine whether any dose is appropriate. Always verify values independently and consult a qualified healthcare professional before making medical decisions.

What's new:
- Fixed a crash that could happen when opening or editing schedules with an end date before the start date.
- Added day-based cycling options for short on/off protocols, with more accurate stock and depletion forecasts for cycling and titrated schedules.
- Improved schedule creation and editing, including the add-today prompt, Mac date display, and safer same-time dose history handling.
- Made iCloud and Apple Health sync catch-up more reliable, with clearer results when data is applied or skipped.
- Polished Insights medication-level charts, metric picker behavior, themed tabs, and several layout edge cases.
