MyPep is the GLP-1 tracker for shots and pills. One simple place to track every shot and everything in between. Use MyPep with Ozempic®, Wegovy®, Mounjaro®, Zepbound®, Rybelsus®, Saxenda®, Trulicity®, compounded semaglutide or tirzepatide, and other weekly or daily injection routines. GLP-1 tracking should not feel like another job. There is shot day, low appetite, protein and water goals, side effects, weight stalls and progress photos. MyPep brings the routine together with less mental load and one place to stay on top of what matters. TRACK SHOT DAYS AND PILLS • Log GLP-1 shots and oral pills in one tap • Weekly or daily schedules with shot reminders • A shot-day checklist with times built around your shot • A countdown to your next shot • Doses left in your pen, with a heads-up before you run out PROTEIN, FIBER AND WATER • Daily protein, fiber and water goals with quick-add portions • Track what matters most when appetite is low • Log steps and workouts to help protect muscle SIDE-EFFECT TRACKER • Rate nausea, fatigue, food noise, constipation, reflux and more on a 0–10 scale • Choose which symptoms you track • Log today or fill in past days • Keep clearer notes to discuss with your healthcare provider INJECTION SITES • Pick the site on a body map when you log a shot • See which areas you used recently so you can rotate PROGRESS BEYOND THE SCALE • Weight trend, goal progress, BMI and estimated goal date • Private progress photos • Full shot history on a calendar WHY MYPEP Food apps focus on calories.
