Regimen vs PepTracker: Which Peptide Tracker Is Right for You?
PepTracker is a popular, well-made peptide dose log: solid calculator, scheduling, and vial tracking. Regimen does all of that too, then goes deeper: 50+ check-in markers, bloodwork, medication-level curves, and an insights engine that connects your doses to how you actually feel. And it runs on iPhone, Android, and web, not just Apple.

More than a dose log
Signals connects every dose to your check-in markers, bloodwork, and health data, then surfaces the patterns.
PepTracker logs your doses and reminds you to inject. Regimen does that, then answers the question a log can't: is it working? Regimen's insights engine (we call it Signals) is purpose-built to connect every dose to 50+ daily check-in markers, your bloodwork, and your health data, and it learns your patterns over time. So you can see whether a peptide actually moved your sleep, your recovery, or a biomarker, not just that you took it.
PepTracker tracks mood and energy once a day and charts your weight; it has no bloodwork, no half-life curves, and no insights layer.
