Most GLP-1 users inject at the same spot every week without realizing it. Repeated injections create lipodystrophy — fatty deposits that reduce how consistently your medication absorbs. A tracker with a body map fixes this. Here's the one that does it best in 2026.
Semaglutide and tirzepatide are weekly injections. Every week you should rotate between your abdomen, thighs, and upper arm. Without a systematic log, you're guessing — and guessing means repeating sites more often than you think.
Site Rotation — What a 3D Body Map Shows You
Protocol's 3D body map tracks every injection — color-coded green (rested), orange (recent), red (today). At a glance you always know where to go next. No other GLP-1 tracker on Android or iOS has this.
Track weight, BMI, and trends alongside your GLP-1 dose log
Tap the compound. Tap the dose. Tap the site. Done. Protocol logs everything with one-tap entry from the home screen or directly from the injection reminder notification. You're not opening a spreadsheet after every shot.
Starting semaglutide at 0.25mg and titrating up every 4 weeks? Protocol tracks your titration schedule and reminds you when a dose change is due. Your full titration history — every dose increase, every date — is visible at any time.
A lot of GLP-1 users also run BPC-157 for gut support, or magnesium and berberine alongside their protocol. Protocol is the only tracker that handles GLP-1 injections, peptide doses, supplements, and habits in one unified protocol with one adherence score. Nothing else comes close.
No account. No cloud. Everything stays on your phone. GLP-1 use is personal — your protocol data doesn't belong on a server somewhere. Protocol includes Stealth Mode to disguise the app icon for complete privacy. Tracking your medication is your business.
Shotsy is iOS only and built for single GLP-1 weekly logging. If that's all you need, it works. The moment you add a second compound, need Android support, or want site rotation tracking, Protocol is the only option. Shotsy was also built before 3D body maps existed in consumer apps.
