Regimen is a peptide and GLP-1 tracker app used by 25,000+ people 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 and progress photos, and sync Apple Health, with a 200+ compound library. It also shows you what keeps repeating. Regimen spots patterns in your doses, side effects, weight and labs and measures them against your own baseline. 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: add anything not in our database 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 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, hematocrit trending up since starting testosterone cypionate, down 40 lbs from where you started. 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. 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, side effects, water retention, joint pain, injection-site reactions, and more. WATCH YOUR LABS MOVE Log every bloodwork pull. See testosterone, lipids, inflammation, glucose, and the rest move with your protocol over time. INJECTION MANAGEMENT Log where you inject every dose, rotate your sites, and see your full injection history. VISUALIZE MEDICATION LEVELS See compound levels in your system hour by hour with half-life plotting. Understand when medications are most active. SEE YOUR TRANSFORMATION Follow your GLP-1 therapy progress and results: weight and body composition over time, plus progress photos as before-and-after pairs, weekly grids, and multi-angle views. NEVER RUN OUT MID-CYCLE Track vials, pens, and tablets with low-stock alerts. Bring your history from another app with CSV import, and export your own data whenever you want.
