Regimen is a peptide and GLP-1 tracker app with 30,000+ downloads, built to log injections, doses, side effects and weight, whether you're on GLP-1 weight loss medication, peptides, TRT or HRT. Plan schedules, rotate injection sites, track vials, bloodwork, nutrition and progress photos, and sync Apple Health, with a 200+ compound library. Free for your first compound, with no time limit. A subscription adds more 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, brand-name or compounded (Semaglutide, Tirzepatide, Ozempic, Mounjaro, Wegovy, Zepbound) - Testosterone replacement therapy (TRT), with your bloodwork and lab results - Hormone replacement therapy (HRT) - Performance compounds - Oral medications, nasal sprays, and any compound with a dosing schedule - Custom medications CUSTOM SCHEDULING Daily, weekly, twice weekly (every 3.5 days), every X days, specific days (Mon/Wed/Fri), as needed, or on/off cycles with start and stop reminders. Set different doses on different days, or several doses a day, each with its own amount. Get a reminder for every dose. Dose titration lets you plan dose increases 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. SEE YOUR PATTERNS Regimen reads your doses, side effects, weight, sleep and labs together and flags the patterns, measured against your own baseline. For example: food noise quieter since your dose went from 2 to 4 mg, or hematocrit trending up since starting testosterone. APPLE HEALTH INTEGRATION Connect Apple Health and automatically sync weight, body fat, lean mass, sleep stages, HRV, resting heart rate, blood pressure, blood glucose, steps, workouts and nutrition, right next to your doses. Overlay any compound against your health data and daily symptoms. Started tirzepatide? Watch your weight respond and compare it to published clinical trial averages. Changed your TRT dose? See how your sleep and energy responded. NUTRITION AND ACTIVITY Keep track of your protein and water with daily goals, plus your steps and workouts, right alongside your doses. SIDE EFFECTS AND DAILY MARKERS Track side effects from your GLP-1 or any other medication, plus 50+ daily markers: energy, mood, sleep quality, libido, cravings, water retention, joint pain, injection-site reactions, and more. WATCH YOUR LABS MOVE Log every bloodwork pull. See testosterone, lipids, glucose and more move with your protocol. INJECTION MANAGEMENT Log where you inject every dose, rotate your sites, and see your full injection history. Each dose card shows your units marked on a syringe, and you can see the planned site for every upcoming dose. VISUALIZE MEDICATION LEVELS See compound levels in your body hour by hour with half-life plotting. Understand when medications are most active. SEE YOUR TRANSFORMATION Weight, body composition and body measurements (waist, hips, chest, arms and more) over time, plus progress photos as before-and-after pairs and weekly grids. NEVER RUN OUT MID-CYCLE Track vials, pens and tablets with low-stock alerts. Import your history by CSV and export your data anytime. YOUR DATA IS PRIVATE Your data is encrypted in transit and at rest, and synced across your devices. We never sell it. You are in full control of your data. IMPORTANT DISCLAIMER Regimen is for tracking and organization only. It does not provide medical advice, recommend doses, or calculate doses or syringe units. Always consult your healthcare provider before starting or changing any protocol. Questions?

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. Milligram Intelligence: An assistant that already has your stack, your doses, your bloodwork and your Apple Health data loaded. Ask "which doses did I miss this month", "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.
