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?
