Regimen is a peptide and GLP-1 tracker used by 20,000+ people - dose logging, scheduling, reconstitution math, injection site rotation, vial inventory, bloodwork, progress photos and Apple Health sync, with a 200+ compound library. Track peptides, GLP-1s, TRT and HRT in one app. Free to track one compound. Subscription for multiple compounds and advanced features, with a 14-day free trial. WHAT YOU CAN TRACK - Peptides (BPC-157, TB-500, GHK-Cu, CJC-1295, Ipamorelin, and more) - GLP-1 medications and pens (Semaglutide, Tirzepatide, Ozempic, Mounjaro, Wegovy, Zepbound) - Testosterone replacement therapy (TRT) - Hormone replacement therapy (HRT) - Performance compounds - Oral medications, nasal sprays, and any compound with a dosing schedule - Custom medications: add anything not in our database BUILT-IN CALCULATORS Reconstitution and dosing calculators built for accuracy. Stop guessing doses. Enter your vial size, BAC water, and intended dose. Get exact units to draw, every time. Works for any compound in mg, mcg, or IU. A reverse calculator, an oil-based mL calculator for testosterone, and a nasal spray calculator are built in. CUSTOM SCHEDULING Set your dosing frequency exactly how you need it: - Daily dosing - Weekly injections - Twice weekly / split-dose (every 3.5 days) - Every X days - Specific days (Mon/Wed/Fri) - As-needed protocols - On/off cycles with start and stop reminders Get reminders that tell you how much to take. Dose titration lets you plan step-ups in advance, for example 2.5 mg for 4 weeks, then 5 mg, then 10 mg, and Regimen moves every dose to the right day. APPLE HEALTH INTEGRATION Connect Apple Health and automatically sync weight, body fat, sleep, resting heart rate, blood pressure, and oxygen saturation. Overlay any compound against your health data and your daily symptom tracking. Started tirzepatide? Watch your weight respond in real time and compare your trajectory to published clinical trial averages. Changed your TRT dose three weeks ago? See exactly how your sleep, energy, and heart rate responded.

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.
