What does the Zepbound tracker record?

Each weekly injection (date, time, the amount you enter and the site), your weight, and how many pens or vials you have. The name starts as Zepbound; you can change it.

Will it tell me when to change my Zepbound dose?

No. This site never suggests amounts or dose changes. The amount field is always yours to fill in from your prescription.

How do I track single-dose pens or vials?

Add them on the inventory panel with the unit “count”. With “Take logged amounts off” on, each taken entry named Zepbound removes one.

What about the KwikPen or multi-dose vial?

The label describes both as holding four doses. Count them with automatic deduction off, and use Adjust (“new pen started”) when you open the next one.

Is this site connected to Eli Lilly?

No. Best Peptide Tracker is published by Peptide Library and isn’t affiliated with or endorsed by Eli Lilly and Company. Zepbound® is a trademark of Eli Lilly and Company.

Zepbound tracker

A once-a-week record for Zepbound®: log each injection with its site, follow your weight beside it, and keep count of the pens or vials you have left.

Pens and vials on hand

How stock changes. You enter how much you have. With “Take logged amounts off” on, each taken entry with the same name comes off the remaining amount when the units match: the same unit, or mg and mcg (1 mg = 1,000 mcg). IU and ml only come off items counted in IU or ml. An item counted in whole containers (count: single-dose pens or vials) loses one per taken entry. Stock never goes below 0, and editing or deleting an entry gives its amount back. Nothing here converts between a vial’s contents and a volume; for concentration math use the Peptide Library calculator.

What the Zepbound label says

From the ZEPBOUND prescribing information

Ingredient: tirzepatide, a GIP and GLP-1 receptor agonist.
Approved uses, with a reduced-calorie diet and increased physical activity: reducing excess body weight and keeping it off long term in adults with obesity, or adults with overweight and at least one weight-related condition; and treating moderate to severe obstructive sleep apnea in adults with obesity.
Injected under the skin once weekly.
Injection areas: abdomen or thigh, or the back of the upper arm when someone else gives the injection; the label says to rotate the site with each dose.
Forms: single-dose pens, single-dose vials, multi-dose vials and single-patient-use KwikPens (the last two hold four doses each).
The label says not to use it together with other tirzepatide-containing products or any GLP-1 receptor agonist.

A weekly log with weight beside it

Save your injection day once and the calendar shows every week: logged, skipped or not logged yet. Weigh in on the same day each week so the trend compares like with like. The chart shows only what you entered; it can’t tell you why your weight changed.

Keeping pen and vial records

Zepbound comes in several forms, so record yours the way it’s counted. Single-dose pens and vials: unit “count”, automatic deduction on, one off per logged injection. KwikPens and multi-dose vials: count containers with automatic deduction off, and adjust when you start a new one. The history shows every change.

Zepbound or Mounjaro?

Both contain tirzepatide but have different labels and approved uses. If yours is prescribed for type 2 diabetes, the Mounjaro tracker adds glucose and A1C fields.
