Milligram is the only health protocol tracking app built on a science-backed database, with an AI assistant that answers based on your real-time health and protocol data.
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.

“Started as free, & I loved it without all the features that now they’ve added! Good simple for pep tracking. Now from all the features, you can’t even use the prior version.” ⭐️Started with the app since it was free, & honestly I love it! Does exactly what it needs to do to. Help you stay on track with your pep journey, and they even went above and beyond so you won’t forget to reconstitute a new vial or how much you have left. Above was my prior review due to a bug kicking me out of my account from time to time, but they’ve fixed it, (Thank you so much) I can honestly recommend it and give it a 5 Star! ⭐️⭐️⭐️⭐️⭐️
Developer Response
Hey, a bug was locking out some of our earlier users, when you should've kept full access. It's fixed in today's update, so please update the app and your access should come straight back. If it doesn't email support@milligramapp.com and I'll be happy to help you out, thanks.

Hey Enzo, I have 2 other peptide tracking apps but to be honest, the design of yours is the cleanest, but not the most practical, I don’t know if I’m mistaken but I can’t see to find any button to log a dose besides the ones you already pre set up, I injected Reta today but it won’t let me log it because it’s already programmed for next week’s Tuesday, also even tho it asked me for my weight and I put it in it just completely ignored it showed that my weight was 123 lb which is guess is like the default the app is programmed to put but when i try to change the weight to 272 now is says that I’ve gained 120 something pounds In the last two days hahaha, but yeah just a little mistakes that should be fixed, more marketing and this project could go big, good luck!

I love this app! Honestly it’s worked great for still being relatively new. It’s super helpful and helps me track how i’m feeling and looking. Highly recommend. Only thing I would suggest is letting founding members invite a few friends for free to join as well to help boost the app and get the word out more!
Developer Response
Hey Calista, thanks so much for the kind words, really glad it’s working well for you and has been helpful so far. On the friend invite feature that’s definitely something we’re looking into right now, stay tuned!

Decent app. Finding it really useful. The logic and flow needs a review and the dosing side should be front and center along with a cycle tracker. Latest update is a big improvement. Logic and flow is better. Dose saving in units from the calculator is a little random and inconsistent.
Connect your protocol to Claude or ChatGPT through the new Milligram MCP server. Your stack, doses, vials and schedule become something your AI of choice can read and reason about. For more info, check out milligramapp.com/mcp
Siri AI (iOS 27): log a dose, skip one, ask what's due or how much is left, through the new Siri AI. There is also a new Log button on the widget and a Control Center control.
New protocol Inventory page: one place for your vials, syringes, swabs, BAC water and more, with storage, expiry reminders, low-stock alerts and supplies that count down automatically as you log doses.
A new Dose History page that allows for seamless and intuitive bulk selection of doses, editing, filtering and more. Plus scheduled doses has been updated alongside this so you can edit your past doses and future doses through a native, seamless design and structure. Change, shift, skip or delete many doses at once.
Also new: iOS 27 optimised tab bar, navigation, toolbars and more. Plus you can now blend vials with their own component amounts, cycle lengths in days or weeks, injection site rotation per compound (choose either per compound or one rotation cycle for everything via profile -> preferences), a strength unit addition per pill, your own currency for protocol costs, and COAs that now work from any lab.
