How MeAgain Tracks Your Zepbound Week
Shot Log, Reminders, and a Late-Dose Window
MeAgain records the dose, time, and site of each Zepbound shot, sends a reminder on shot day, and counts down to the next. Zepbound is a shot you take once a week. Miss a shot and the next-dose card marks it overdue for 4 days, the window the label gives for a late dose, before it moves on to your usual day. Your whole shot history stays in one list you can scroll back through.
Each Dose Step in Your Shot Log
MeAgain saves the dose with every shot and dates each weight, symptom, and meal entry, so looking back shows what changed after a step. Zepbound starts at 2.5 mg for 4 weeks, moves to 5 mg, and can rise in 2.5 mg steps after at least 4 weeks on each dose, up to 15 mg. Reaching the top dose takes 20 weeks or more. With Premium, Journey Cards and progress photos add what the scale leaves out. If you switch medications, your past logs keep the medication they were logged with.
Injection Site Rotation
MeAgain marks each Zepbound shot on a body map and, with alternating turned on, points you to the other side next time. You keep the rotation going without trying to remember last week. The label names the abdomen and thigh for shots you give yourself, and the back of the upper arm when someone else gives the shot, and it asks you to rotate sites with every dose.
Side Effects, Scored and Dated
MeAgain gives you 29 built-in options plus your own, each scored 0 to 10 and saved with the time. The label's most common side effects start with nausea, diarrhea, vomiting, and constipation, and they tend to cluster after a shot or a dose increase. Scroll back through the dated entries to check whether indigestion faded by the second week at a new dose, or whether tiredness follows shot day.
Food, Protein, and Water When You Eat Less
MeAgain logs meals by photo, barcode, voice, search, or quick entry and tracks protein, fiber, and water against daily targets. The label notes that tirzepatide lowers how much people eat, so the daily job shifts to getting enough protein and drinking enough water. The Capybara home screen widget keeps those numbers in sight from your phone's home screen, which helps on low-hunger days.
Your Estimated Tirzepatide Level
The MeAgain medication graph estimates your tirzepatide level from your shot log. Tirzepatide, the medicine in Zepbound, has a half-life of about 5 days, so its level rises after each shot and falls through the rest of the week, which helps explain why hunger returns near shot day. It is an estimate, not a lab value, and it never recommends a dose.
Zepbound Basics: What to Know While You Track
Zepbound is tirzepatide, a weekly shot from Eli Lilly that acts on two gut hormone signals, GIP and GLP-1. The FDA label approves it together with a lower-calorie diet and more physical activity to lower body weight and keep it off in adults with obesity, or with overweight and at least one weight-related health problem. It is also approved to treat moderate to severe obstructive sleep apnea in adults with obesity.
The most common side effects on the label are nausea, diarrhea, vomiting, constipation, and stomach pain. Indigestion, injection site reactions, tiredness, allergic reactions, burping, hair loss, and acid reflux are also on that list. In the SURMOUNT-1 trial, 2,539 adults with obesity or overweight took tirzepatide or a placebo for 72 weeks; those on 15 mg lost 20.9% of their body weight on average, compared with 3.1% on placebo.
Zepbound dose schedule
From the current FDA label. Zepbound is taken once a week.
| When | Weekly dose | Step |
|---|---|---|
| Weeks 1 to 4 | 2.5 mg | Starting dose |
| Week 5 on | 5 mg | First maintenance dose |
| After 4+ weeks at 5 mg | 7.5 mg | Raise if needed |
| After 4+ weeks at 7.5 mg | 10 mg | Raise if needed |
| After 4+ weeks at 10 mg | 12.5 mg | Raise if needed |
| After 4+ weeks at 12.5 mg | 15 mg | Highest dose |
Your prescriber picks the dose you stay on, based on how well it works and how you feel. The label's maintenance doses are 5 mg, 10 mg, or 15 mg for weight; for sleep apnea, they are 10 mg or 15 mg. If you miss a shot, the label says to take it within 4 days, or skip it and keep your usual day. This table summarizes the FDA label for education only. It is not medical advice.

What Our Users Say
“I've been on MeAgain for about 3 weeks to help me stay on track with my protein, fiber and water needs while taking my Zepbound. I really like the ease of tracking foods and the fact that I can see my progress.”
“MeAgain is the most complete shot solution I have tried. I keep all my zepbound shot records and can show my doctor my progress over time.”
“Love love this app. It has everything I need. From giving an estimate on how much Zepbound is in my blood to not having to enter every ingredient in a made-from-scratch meal. I'm sure it's an estimate but don't care!”
“I like how MeAgain makes it easy to log my food and keeps me updated on when it's time to take my Zepbound.”
“I just started Zepbound last week. It was a huge mental hurdle along with the other tasks that come along with keeping track of what I eat and drink(Water intake), how I exercise and all that. MeAgain has helped me get under way and I’m already down almost 5lbs. I think it is a great asset to pair with a GLP-1… without it I think I’d be lost in the sauce.”

MeAgain. It counts your protein, fiber, and water for each day and keeps those totals next to your Zepbound dose and side effects, so you can see how eating changes after a step up. Meals go in by photo, barcode scan, voice, search, or quick add, and all five ways are free.
