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.

A peptide tracker that keeps you peptide protocol organized. Log every GLP-1 and peptide dose, see your prescribed dose in the units on your syringe, organize your vials, rotate injection sites, and get gentle reminders so you never miss a shot. No account. No sign-up. Free to start. Peppy is a peptide tracker and logbook. It is not a medical device and it never recommends a dose. You enter the dose you and your provider already decided on; Peppy records it and keeps you organized and consistent. WHY YOU'LL LOVE PEPPY • No account, no sign-up. Open the app and start tracking in seconds • Your health data stays on your device and in your own private iCloud. Never on our servers • Built for GLP-1 and metabolic peptides, branded or compounded, plus custom peptides you add yourself • A peptide tracker with a clean, uncluttered design and a friendly mascot to keep things light • Thoughtful safety reminders at every step TRACK YOUR DOSES A peptide tracker is only as good as its log. Record every injection and see your full history at a glance: what you took, when, and what's next. Back-date a dose you forgot, spot missed doses, and build a streak week after week. YOUR PRESCRIBED DOSE, LOGGED Enter the vial you use and the dose your provider prescribed. Nothing is pre-filled and nothing is suggested: every number is the one you typed, and every screen reminds you to follow your provider's instructions. ORGANIZE YOUR STASH AND VIALS Keep every peptide in one stash, track how much is left in each vial, and watch mixing and expiry dates so nothing goes to waste. Set up a new vial from presets in a couple of taps, and get a nudge when it's time to refill. ROTATE INJECTION SITES An interactive body map records where you injected and suggests your next site, so you rotate properly and never overuse one spot. NEVER MISS A DOSE Daily or weekly reminders that fit your routine and adapt as your schedule shifts. Schedule-aware, so reminders keep pace with the plan you entered. Home Screen and Lock Screen widgets show your next dose and vial levels without opening the app. TRACK YOUR PROGRESS Log weight and symptoms alongside your doses and see clear trends in simple charts, so you and your provider can see how the plan is going. One peptide tracker for the whole picture. SAFETY FIRST Clear disclaimers appear throughout the app, and every dose screen reminds you to follow your provider's instructions. Peppy never recommends a dose, never sources or sells peptides, and never offers medical advice. Always follow the guidance of your licensed healthcare provider. PRIVATE BY DESIGN Your doses, weight, symptoms, and notes are stored on your device and, if you choose, synced through your own iCloud account. They are never uploaded to our servers, and there is no account to create. We collect anonymous, non-health usage analytics only if you opt in, and an advertising-measurement tool runs only if you allow tracking. See our Privacy Policy for full details. SUBSCRIPTION Peppy offers a subscription with a free trial. Plan options, durations, and prices are shown in the app and may vary by region.
