Your whole stack, tracked in one app
Built for peptides, GLP-1s, TRT and whatever else you run. Every dose scheduled, every vial accounted for, blood levels modelled as they move, and labs you can actually read.
Track every dose, vial and trend.
What you took, what you have left, and where your levels sit today.
Vials
10 mg mixed, three spares in inventory. Doses draw it down, refills reset it, and you see a vial ending weeks out.
Levels
26.0 ng/mL, 34% of peak. Every logged dose feeds a half-life model, so your level is a number, not a feeling.
Watch your body respond.
The protocol is half the picture. The other half is what your body does with it.
Apple Health
Connect your health data and trends.
- Sleep

Four signals, synced from Apple Health and lined up against your protocol. When a number moves, you can see what you were running when it did.
Body scan
Track body fat with your camera.
Point your camera at a mirror. Milligram estimates your composition and tracks it scan over scan, beside your weight.
Food scan
Point. Scan. Logged.
Scan the plate, the label or the barcode. Milligram reads what is there, logs it and counts it against your day in seconds.
Know what your bloodwork says.
Feeling good and testing well are not the same thing.
Health records
Upload your labs.
However your clinic sends it, Milligram can read it.
- Formats
- PDF, photo or screenshot
- Extraction
- Every marker, pulled out automatically
- Ranges
- Taken from your own lab's results
- Privacy
- Encrypted, never shared with third parties
Milligram Intelligence
Then ask anything.
Nothing to paste in, no numbers to look up. It already holds your panels, your history and your current protocol, and it reads all three before it answers.
- It reads your records first Every panel, the marker timeline, and what you were taking.
- Then tells you what changed Marker by marker, which way it moved and where it landed.
- And what is worth asking next Follow-ups drawn from what it actually found in your results.

26 Jun 2026Must have!!!
This app is incredible!! Never made a review on anything before, but I felt this was very deserved. All of the info on peps, dosing and side effects is invaluable, but even better is the ability to upload and compare bloodwork, get personalised help from the built in AI, and track the peak of your pep effects. Never come across anything like it. Cannot recommend enough!!

9 May 2026Must get to track peps!!
This app is a hidden gem without a doubt. The features are great, reminding you when to take your doses at your desired frequency and allowing many different peptides to be tracked at once. What stands out most is the AI feature that personalises its response according to your dosage and usage.

Such a good app, have been using this since it came out, back when the app was green. The AI has come a long way and is such a helpful thing within the app, and the milligram support has been so helpful. The best thing about the app is the AI, such a game changer.

It's easy to use and understand, really customisable. I found it really hard to even find a peptide app that allows for twice a week injections but this one does. Love it!

Really loving this app! Super easy to use and makes tracking everything so much simpler. The reminders are great and help me stay consistent without even thinking about it. It also really helps with dosages and general info, which takes a lot of the guesswork out.

5 Jul 2026Too good to be true
Helps 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. I can honestly recommend it and give it a 5 star!

Have just downloaded the app and I'm loving it so far. Being able to track your peptides is amazing, with the check-ins as well. One feature I really love is the facial scan, an absolute game changer especially for me going through weight loss.
