Tirzepatide tracker: one log for pens and vials
For planning and record-keeping only — not medical advice. Your dose and schedule are set by your prescriber.
A tirzepatide log looks the same no matter which form you're on: shot date, dose, injection site, weight. What differs is the dose entry — a pen delivers a labeled mg dose, while any vial is drawn with a syringe you supply, and a multi-dose or compounded one turns that dose into syringe units worked out from mg and concentration.
KeepAlong — GLP-1 shot tracker & planning tools
KeepAlong logs any weekly tirzepatide schedule — starter pen, maintenance dose, or a dose drawn from a vial — with injection-day reminders and a home-screen widget counting down to the next shot. Vial users keep a dose journal in mg with room for the units behind it.

Pens and vials: what changes in the log
Tirzepatide has the widest spread of containers of any GLP-1 medication. Both brand labels list four of them — single-dose pens, single-dose vials, multi-dose vials, and a single-patient-use KwikPen — and compounded tirzepatide adds vials of its own. A log built around the molecule handles all of them, which matters because prescriptions move between these forms more often than any single product page admits.
Mounjaro, prescribed for type 2 diabetes, and Zepbound, prescribed for weight reduction and for moderate to severe obstructive sleep apnea in adults with obesity, are supplied in the same containers: single-dose pens and single-dose vials in all six strengths, plus multi-dose vials and KwikPens carrying four weekly doses at 10 to 60 mg per 2.4 mL (both labels checked 2026-08-18). Their weekly routines are covered on the Mounjaro tracker and Zepbound tracker pages. Every vial is drawn with a syringe and needle the labels state are not included, and a multi-dose vial — brand or compounded — additionally turns the prescribed mg into syringe units through the concentration on the label, which is exactly the conversion the units calculator runs in your browser. For a dry vial, the reconstitution calculator handles the earlier question of how much bacteriostatic water to add.
A pen or single-dose vial entry
- Shot date and dose in mg
- Injection site you rotated to
- Weight for that week
- A note on how the week went, if you keep one
A multi-dose vial entry adds
- Units drawn on the syringe
- Concentration in mg/mL from the label
- Which vial the dose came from
- Reconstitution date for doses you mixed
The extra fields are the whole difference. Weekly cadence, site rotation, and the weight trend behave identically across containers, so one journal carries a switch from pen to vial — or brand to compound — without a break in the history.
Titration dates work the same way
Mounjaro and Zepbound share a single six-step ladder — 2.5, 5, 7.5, 10, 12.5, and 15 mg — and one pacing rule: at least 4 weeks on a step before moving up, per the FDA prescribing information for Mounjaro and Zepbound (checked 2026-08-18). The 2.5 mg start is not a maintenance dose, and not every prescription climbs all six rungs — holding at a middle step is common and allowed by both labels. A compounded schedule follows whatever your prescriber wrote and may pace slower; the log entry is the same either way, the date each new step begins. The titration date planner converts the ladder and your first-shot date into the earliest date each step could start — the decision to actually take a step stays with your prescriber — while the tirzepatide dosage chart lists every strength and which of them the labels treat as maintenance.
A six-rung ladder spreads over months, so dates drift unless the log pins them down: the day a new strength started, and how many weeks the current one has run. That pair of numbers is what makes the history useful at follow-ups, and it costs one line a week.
What to write down every week
Four items carry the log: date, dose, injection site, weight. The longer checklist — and what's genuinely skippable — lives in what to track on GLP-1; the injection sites map shows the three label-approved zones to rotate through. When a spreadsheet starts feeling like a second job, a GLP-1 shot tracker app does the same work in two taps — and the best GLP-1 tracker apps roundup compares the options if you'd rather choose deliberately.
Frequently asked questions
Is tracking compounded tirzepatide different from Mounjaro or Zepbound?
The entry changes, the habit doesn’t. A compounded dose is measured in syringe units from the vial’s stated concentration, so you log units and mg/mL next to the mg. Storage is pharmacy-specific too: the beyond-use date on your pharmacy’s label applies, not the fridge windows printed for brand pens.
Do brand tirzepatide vials need the units math?
A single-dose vial does not: it holds one complete 0.5 mL dose, so the log entry is simply the mg, the same as a pen. Units-from-concentration math enters with multi-dose vials, where one container spans four doses at a stated mg/mL. Either way the syringe and needle are yours to supply — both labels state they are not included (checked 2026-08-18).
Can one log cover a switch between Mounjaro and Zepbound?
Yes, as a record. Keep one journal, write the product name in every entry, and note the date anything changed — the weekly rhythm, site rotation, and weight trend then continue uninterrupted across the switch. What the new prescription says, including its strength, is a decision for your prescriber, not something a log converts.
When can you skip a tirzepatide tracker?
When the routine is static: a settled maintenance dose, a fixed weekday, and no interest in lining weight up against dose history. A recurring phone alarm covers that case. A tracker earns its keep during the long six-step climb, when every step has a date and the numbers multiply.
