The Ultimate Peptide Tracker & Calculator for All Your Protocols Take control of your peptide journey! Whether you're deep into peptide research, optimizing for fitness with performance peptides, aiding recovery with compounds like BPC-157 or TB-500, exploring biohacking protocols, or managing GLP-1 agonists like Semaglutide and Tirzepatide, Peptide Tracker & Calculator is your essential management tool. Stop relying on messy notes or complex spreadsheets – track everything accurately in one secure, easy-to-use app. Comprehensive Peptide Inventory Management: Log Any Peptide: Maintain a detailed database of all your compounds – from research peptides and GHRP/GHRH analogs (like CJC-1295 or Ipamorelin) to healing peptides and GLP-1s. Track Critical Vial Data: Record concentration (mg/mcg), units, vial size (ml), diluent (e.g., BAC water), date, storage conditions (fridge/freezer), source, batch number, and expiration dates. Essential for consistency and safety across all peptide protocols. Smart Low Stock Alerts: Visual indicators warn you when any peptide vial is running low, helping you reorder before interrupting your research, peptide cycle, or therapy. Precise Dose Logging: Accurate Dose Recording: Log every administration with meticulous detail: specific peptide used, dose amount (mg/mcg/IU), date/time, method/site (subcutaneous, intramuscular), and personal notes for context (e.g., "pre-workout," "post-injury"). Complete Dose History: Review your entire usage history for any tracked peptide. Filter logs by compound (e.g., view all BPC-157 doses) to analyze patterns, effectiveness, and adherence. Perfect for managing complex peptide stacks or cycles. Intelligent Injection Site Rotation: Smart Site Tracking: Maintain a personalized map of injection sites with customizable rest periods for optimal absorption and tissue recovery. Rotation Recommendations: Receive intelligent suggestions for your next injection site based on usage history and proper rotation patterns. Site Status Monitoring: Color-coded indicators show which sites are ready for use, need rest, or are inactive, helping prevent site overuse and associated complications.

Whether you're optimizing for fat loss, muscle gain, longevity, recovery or anti aging, Milligram is for people who want to take back control of their health protocols with science-backed confidence. Every other tracker gives you a tidier place to write down what you already did. Milligram models what is actually in your system right now. Every dose charted against every half-life. Everything in the stack with info and the database covering over 3,581 references total. Bloodwork read against what you are actually running. And an AI assistant that answers from your real-time numbers, read against a database made specifically for your protocol, not everyday questions. FEATURES Your Protocol: Everything you run, on one screen. Each compound with its own schedule, dose, vial and supply tracked, and the whole protocol read as one picture rather than being scattered across different notes, files and spreadsheets. Dose tracking: Log every dose, whether that's an injectable or an oral supplement - Milligram works with every compound and every dosing route. Reminders arrive on the protocol's schedule and know which compound, which dose and which injection site. Milligram Intelligence: An assistant that already has your stack, your doses, your bloodwork and your Apple Health data loaded. Ask "which doses did I miss this month", "how is my weight tracking against my retatrutide cycle", or "did my IGF-1 move on tesamorelin", and get an answer from your own numbers. Level Buildup: See your compound levels build from each trough to peak. Every dose is charted against the published half-life of your compound, so you know exactly when you've reached the right zone at the right titration, how each dose is keeping you there, and how much a missed dose can actually move the needle. Bloodwork: Upload a PDF or a photo of your labs. Every biomarker is extracted and out-of-range values flagged, then kept where they can be read against the compounds that might be moving them. Compound Library: 202 compounds with mechanisms, dose ranges, half-lives, expected timelines and side-effect profiles, each referenced to clinical sources. Retatrutide, tirzepatide and semaglutide. Testosterone esters, Masteron, Anavar. Tesamorelin, BPC-157, GHK-Cu, MK-677, Ipamorelin and CJC-1295. Creatine, Omega-3 Fish Oil, Magnesium, Zinc, Vitamin D3, and more. AI calorie and nutrition tracking: Scan any meal with your camera. Snap a photo, scan a barcode, or scan a nutrition label and Milligram extracts calories, protein, carbs and fat instantly. Track every meal against your daily targets with a clean macro breakdown. Apple Health: Two-way sync for sleep, HRV, vitals, activity, weight and body composition, so protocol data and health data sit in the same timeline.
