Regimen vs Shotsy: Which GLP-1 Tracker Is Right for You?
Shotsy is the most popular GLP-1 shot log, and a good one. Regimen tracks your Wegovy, Zepbound, Mounjaro, or Ozempic the same way, then connects the dots: the stuff that actually moves your week (food noise, nausea, energy, sleep, constipation, injection-site soreness) plus bloodwork and your estimated medication-level curve, all read back to you by Signals so you're not scrolling through logs to figure out why a day felt off. You can also add progress photos so you've got a real record of the journey, not just a weight graph, plus other compounds whenever you want. The medication-level curve Shotsy currently gates behind premium is free here.

We make Regimen, so this isn't an independent review; we try to be useful by naming where Shotsy is better.
More than a shot log
Track your GLP-1 alongside other peptides and supplements, with medication-level curves built in.
Shotsy logs your shot. Regimen logs the shot and reads your week back to you. Track the check-ins that actually shape a GLP-1 week (food noise, nausea, energy, sleep, constipation, injection-site soreness) alongside your dose, and Signals watches your check-ins and tells you the pattern it finds: your food noise tends to creep back around day 5, or your energy dips as the dose wears off. That's what "understanding your journey" means here, not more charts.
And if your routine changes later (a peptide for recovery, TRT, or a supplement you want to measure) it lives in the same app, with its own schedule and reminders. You're not stuck in a single-purpose tool the day your stack changes.

Why Regimen wins
It reads your week back to you. Signals turns your GLP-1-native check-ins and dose history into an actual pattern you can act on, not another chart to interpret.
Depth where it matters. 50+ GLP-1-native markers, detailed side-effect tracking, and bloodwork, all mapped to your Wegovy, Zepbound, Mounjaro, or Ozempic dose history.
Medication-level curve, free. Free for your first compound in Regimen.
It grows with you. Add other peptides, TRT, or supplements later without switching apps.
Where Shotsy is strong
It's the most popular GLP-1 tracker, with a large, established community. If a GLP-1 is all you track and you want the option the most people use, it's a reasonable choice.
Built-in food and nutrition logging (calories, protein, water), which Regimen doesn't do. If you want your shot log and your food log in the same app, Shotsy wins there.
Which app should you use?
Choose Regimen if you want the app to interpret your week for you (Signals on your GLP-1-native check-ins, side effects, bloodwork), you want the medication-level curve without paying extra, or you might track other compounds later.
Choose Shotsy if a GLP-1 is the only thing you track, you want the most popular app and its community, or you specifically want built-in food logging.

Which is better, Regimen or Shotsy?
Shotsy is the most popular GLP-1-only tracker and it's a solid shot log.

Both track Wegovy, Zepbound, Mounjaro, and Ozempic well.
