Milligram is the only protocol tracking app built on a science-backed database, with an AI assistant that answers based on your live health data and protocol metrics.
Whether you're optimizing for fat loss, recovery, longevity, or appearance, Milligram is for people who actually want to take control of their protocol and health with science-backed confidence. See your compound levels, get dose reminders, upload your bloodwork, connect your health apps and wearables to turn every dose into data you can read.
FEATURES
Milligram Intelligence: Your in-app agentic protocol analyst. Milligram Intelligence knows your real-time stack, uploaded bloodwork, your goals, apple health data and more; all updated and saved to your in-app, on-device memory files. Start every chat with your data pre-loaded. Ask anything: "how's my weight loss tracking alongside my retatrutide cycle?", "did my IGF-1 move on tesamorelin?", and get instant answers and analysis grounded in your real-time protocol statistics, health data and our clinically-backed database, not through a generic AI chat-bot.
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, how each dose is keeping you there, and if a missed dose can actually move the needle.
Bloodwork Analysis: Upload a PDF or photo of your lab results. Milligram extracts every biomarker and flags out-of-range values. Your data is saved to your secure in-app file system, always accessible to your personal agent. Getting bloodwork done finally pays off.
Compound Library: 200+ compounds with mechanism breakdowns, dose ranges, half-lives, expected timelines, and side-effect profiles. Every peptide, GLP-1, testosterone ester, performance compound and supplement; each with referenced clinical sources.
Progress Scans: Face and bodyfat scans turn before-and-after into actual data. Estimated body-fat, facial alignment; subtle changes tracked that you can't catch in the mirror. Body comp and skin clarity; mapped against your stack so you can see what's actually pulling weight.
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.
Journals & Metrics: Track sleep, energy, mood, libido, hunger, focus, side effects, and anything else on a unified 1-10 scale. Top-of-Progress gauges surface your three most relevant metrics with personal-range arcs, weekly drift bands, and monthly intelligence reports.
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.
Apple Health: Two-way sync for sleep stats, heart rate variability and body composition. Milligram Intelligence pulls your live health data and can answer anything related to your protocol cycle and health metrics, giving you real insights that you might've missed.

“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.
Thank you for your ongoing support and use of Milligram. This is the most work we have ever put into one update, and nearly all of it went into the screens you use every day. Home has been redesigned from first principles, and your schedule now works the way you actually dose and use the app day-to-day instead of the way it's strictly made to be written down. Read below for all the changes:
Home and dose schedules
– The top of Home is now an interactive dial representing a days due doses, instead of singular countdown. Tap it to switch between between dose/compound info with ease.
– Editing your schedule no longer changes your past. Move a compound from Monday to Tuesday and every Monday you already logged stays where it was.
– Doses taken after midnight count towards the day before, up to 3am - to allow for late night doses to properly match your late sleep schedules.
– Postpone a dose. Hold it on your schedule and move it to a later time or date. The reminder and the projection move with it, and it is never counted as missed when it wasn't.
– Logging after the fact asks you what time you took it. Backdated doses no longer get stamped with the time you logged it in the app, but when you actually took it.
– A dose is marked missed when its scheduled day ends, not when its arbitrary dose window time passes; for example: weekly compounds are no longer flagged missed a few hours after the reminder.
– Tap a row to log it. Hold it or tap the three dots for postpone, skip, edit and delete.
New and improved: daily routines
– Schedule a weigh in, a body scan or a journal entry on the home tab, right below your dose schedules, each with its own reminder.
Layout and settings
– On iOS 26 you can set your fourth tab to the Calculator, to Profile, or to neither. You can also choose where Milligram Intelligence sits easily from from navigation settings, and stop the tab bar shrinking when you scroll if preferred.
– New account page, and one notifications page listing everything the app can send you, each switchable on its own. Much more customisability.
– Every settings row now has a coloured native styled icon, so you can find exactly what you're looking for with a scan, instead of having to dig through.
Milestones rework
– 22 new beautiful 3D interactive medals across 11 series, earned for doses logged, perfect streaks, meals tracked, weight goals being achieved and more.
New app icons
– 5 new app icons across three sets. Some are available immediately, others unlock alongside medals. Check them out in the profile tab
And everything else:
– Current Level moved onto the pharmacokinetics push-page inside each compound's hub. Next dose card runs full width to replace its space.
– Charts inside a compound now match the ones on Home, and the pharmacokinetic charts are more interactive and show information cleaner.
– Nutrition settings are split across separate sub-pages instead of one long scroll, and body composition is now on a single card in health trends.
– Fixed a crash that could stop Home from loading for a small number of people when pharmacokinetic chart visuals and backend logic didn't agree.
– Speed and stability work throughout, plus you'll notice a lot of surfaces feeling and looking more polished, consistent, and intuitive.
