Milligram is the only peptide tracking app built on a science-backed database, with an AI agent that answers based on your real-time health data and compound statistics.
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: 150+ 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.

Hey yxngramirez, great idea - we’re actually already working on an inventory tracking system that includes this too! Let us know how you find it when the update is live :)

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!
Developer Response
Hey, really appreciate the detail. A quick heads up—you can actually log doses any time by switching the peptide dosing frequency to “as needed” in the editor. That’s clearly not discoverable enough though, so I’ll fix the UX in the next update. The weight issue looks like a kg/lb conversion bug, which we have fixed in our next update. Also, the next update is a full revamp of weight logging (plus a bunch of other health metrics) with Apple Health sync, so all your metrics will pull through automatically and be way easier to manage. Thanks for taking the time didi 🙏

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.
Developer Response
Hey brendona, thanks for the review. Really glad you’re finding it useful so far. The backend logic for some of the pharmacokinetic live curves for sure needed a tweak and we’re glad to say that after many iterations we have found a way to present the info in the best and most accurate way possible now :)
Bug fixes and performance upgrades.
