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. Reconstitution Calculator: Mix any vial, any concentration. Convert mg, mcg, IU, and units for compound preparation. Designed for accurately mixing peptide vials with bacteriostatic water - saved to your compounds for quick reference. Milligram Intelligence: An assistant that already has your stack, your doses, your bloodwork and your Apple Health data loaded. Ask "what do I draw for 5mg from a 10mg vial in 2ml", "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.

PeptidePal is a peptide and GLP-1 protocol tracker used by over 150,000 people — dose logging, vial inventory, injection site rotation, reconstitution math, scheduling, and a 110+ compound library in one app. Whether you're on a prescribed GLP-1, running your first protocol, or managing several compounds on different schedules, PeptidePal keeps it all in one place. WHY PEPTIDEPAL? ◉ BUILT FOR PROTOCOLS, NOT PILLS: Generic medication apps track one pill, once a day. PeptidePal handles mcg, mg, IU and mL, cycles, on/off weeks, site rotation, and vial lifecycle. ◉ NO DRIFT: Three weeks in, it's easy to lose track of whether you're on day 9 or day 12. PeptidePal keeps the protocol you designed and the protocol you're running the same thing. MAIN FEATURES: ▶ PROTOCOL BUILDER Build from the library or from scratch. Set dose (mcg, mg, IU, mL), frequency (daily, every other day, twice weekly, 5-on/2-off, custom), days, start date, notes, and reminders. Run multiple protocols side by side. ▶ DOSE LOGGING & CALENDAR One tap to log. A week strip and monthly calendar show completed and planned doses, injection site, and time. Streaks keep you consistent. ▶ VIAL INVENTORY & SUPPLY ALERTS Log fill size, concentration, and expiry. PeptidePal projects each vial's run-out date from your live schedule and warns you about a week ahead. ▶ RECONSTITUTION MATH Enter vial size, diluent volume, desired amount, and syringe size. PeptidePal does the mg/mL arithmetic and shows it on a syringe diagram, with an over-capacity warning. Unit conversion only — PeptidePal does not recommend a dose. ▶ INJECTION SITE ROTATION Tap-to-select on an interactive body map, with recently used sites heat-mapped so your rotation is visible at a glance. ▶ COMPOUND LIBRARY 50+ profiles in plain English: mechanism, half-life, research status, reported side effects, and considerations. Every entry states its regulatory status. ▶ PROGRESS & LEVELS Weight and body-composition charts, progress photos with compare and time-lapse, and an estimated on-board level curve from your logged doses. Educational estimate, not a measurement. ▶ AI ADVISOR & COMMUNITY Q&A Short, plain-English answers to educational questions, plus a moderated peer forum. The AI will not recommend a dose, titration, or protocol, and routes medical questions to a provider. You're talking to an AI, not a clinician. Does PeptidePal work with prescribed GLP-1s? Yes — track Ozempic®, Wegovy®, Mounjaro® or Zepbound® with the same scheduling, rotation, and supply tools. Dosing decisions belong with your prescriber. Is my data safe with PeptidePal? Protocol data is stored on your device Progress photos are stripped of metadata before storage Analytics are anonymous — no advertising identifier, no cross-app tracking We do not sell your data or share health information with advertisers Delete your account and all associated data from Settings, in two steps Medical disclaimer PeptidePal is a tracking and educational tool.

The call

Milligram and PeptidePal both sit at 4.7 stars, but that hides the real split: 69% of Milligram's written reviews are positive against 30% of PeptidePal's.
