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+ daily 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.
Quick Answer
PepTracker is a great pick if you want a simple, proven dose log and you’re on an Apple device. Choose Regimen if you want to understand what’s working, not just log it: 50+ daily markers, bloodwork tracking, half-life curves, and an insights engine that finds patterns across your protocol, on iPhone, Android, or the web. Regimen is free for one compound.
More than a dose log
Regimen connects every dose to your daily 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 pattern detection is purpose-built to connect every dose to 50+ daily 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.

Why Regimen wins
You understand what’s working, not just log it. A purpose-built insights engine across 50+ markers, bloodwork, and health data.
Bloodwork tracking and half-life curves PepTracker doesn’t have.
Runs on iPhone, Android, and web. PepTracker is Apple-only.
Price. PepTracker is the cheaper subscription, and its free tier covers two protocols where Regimen’s covers one. What the difference buys is depth: bloodwork, half-life curves, 50+ daily markers and the insights layer, on Android and the web as well as iPhone.
Where PepTracker is strong
It’s the most-reviewed dedicated peptide tracker (4.7 stars, 362 ratings) with a loyal iOS following. If you want a proven, focused dose log, it does that well.
Polished core. A good dose and reconstitution calculator with syringe visuals, flexible scheduling, vial inventory with remaining-dose tracking, and free unlimited calendar sync (Apple and Google).
Which app should you use?
Choose Regimen if you want to see what’s actually working (markers, bloodwork, half-life curves, insights), or you’re on Android or want web access.
Choose PepTracker if you want a simple, proven dose log, you’re on an Apple device, and you don’t need bloodwork, half-life curves, or an insights layer.
Frequently Asked Questions
Is Regimen free for peptide tracking?
Yes. One compound free, plus a 14-day trial: 50+ daily markers, bloodwork, half-life curves, reconstitution calculator, and insights. Premium adds unlimited compounds.
Which is better, Regimen or PepTracker?
PepTracker is the most-reviewed peptide dose log and great if you want something simple on Apple devices. Regimen is the better pick if you want to understand your protocol: 50+ markers, bloodwork, half-life curves, and a purpose-built insights engine. It also runs on Android and web.
Does PepTracker track bloodwork or health metrics like Regimen?
No. PepTracker tracks mood and energy and your weight. Regimen adds 50+ daily markers, bloodwork, and an insights engine that maps it all to your dose history.
Does PepTracker work on Android?
No, PepTracker is iPhone and Apple Vision only. Regimen is on iPhone, Android, and web with cloud sync.
Can I switch from PepTracker to Regimen?
Yes. Set up your protocol in about 30 seconds; CSV import is available.
Which app has a better reconstitution calculator?
Both apps include reconstitution calculators. Regimen's calculator is built into each compound profile so you can calculate your dose and log it in the same workflow. PepTracker's syringe calculator handles the same core math.
Can Regimen track peptide cycles?
Yes. Regimen supports configurable on/off cycling for peptides with alerts when it's time to cycle off. You can set custom cycle lengths for each compound in your protocol.
Is PepTracker free?
PepTracker's free tier covers two protocols. Beyond that it needs a subscription. Regimen is free for one compound with no time limit and no card, plus a 14-day trial.
Which app is better for peptide stacking?
Regimen is designed for multi-compound protocols. You can track BPC-157, TB-500, CJC-1295/Ipamorelin, and any combination with independent schedules and see how each compound correlates with your health metrics. PepTracker handles multiple protocols but doesn't offer health metric correlation.
