GLP-1 tracking

Track your GLP-1 shot, week by week.

The short answer

What makes a good GLP-1 shot tracker?

A GLP-1 shot tracker should log the weekly shot on its day, keep the dose step you're on and the next one in view, rotate injection sites, and put side effects and your weight trend next to the doses. Shotsy and MeAgain are built for GLP-1 medications alone and keep their core tracking free. PepVault, our iPhone app, tracks a GLP-1 next to peptides, with bloodwork and an AI coach that reads your whole log. It works with semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound), in pens or vials.

What to track, and why.

  1. 01

    The shot, on its day.

    Semaglutide and tirzepatide are both taken once a week, on a steady day. Log each shot with its time; a reminder on shot day keeps the week from slipping.

  2. 02

    Your dose step, and the next one.

    Both start at a low dose and step up in four-week steps on their labels, as your prescriber decides. Keep the step you're on and the date of the next, and side effects line up with the change that came before them.

    Pens or vials.

    A pen holds a set number of doses; a compounded vial is drawn with a syringe. Either way, counting down what's left keeps the next box or vial ready in time.

    Rotate the site.

    Stomach, thigh or upper arm: a log of where each shot went makes the next one easy to pick, for a pen or a syringe.

  5. 05

    Side effects and the weight trend.

    Commonly reported: nausea and a smaller appetite in the first days after a dose step. Logged next to the doses, they show which step brought what, and a weight trend, a smoothed line through every weigh-in, shows the direction under the day-to-day noise.

Can I track Ozempic, Wegovy, Mounjaro or Zepbound in PepVault?
