What Is Regimen? The Peptide, TRT & GLP-1 Tracking App
What Is Regimen?
If you've ever tried to track peptide doses in a notes app, set injection reminders in your Google Calendar, or kept a spreadsheet of your TRT protocol, you already know why Regimen exists.
Regimen is a tracking app built specifically for people using peptides, testosterone replacement therapy (TRT), and GLP-1 medications like semaglutide and tirzepatide. It replaces the patchwork of notes, alarms, and spreadsheets with a single app that actually understands what you're tracking.
You log your injections, set dose reminders, record side effects, and monitor your protocol over time. It tracks injection sites so you're rotating properly. You can track medication levels and correlate them with health metrics to spot patterns over time.
The website also has a full set of free calculators for peptide reconstitution, GLP-1 dosing, testosterone dose math, and more. Those work in the browser, no app download required.
Who Is Regimen For?
People on peptide protocols. BPC-157, TB-500, MK-677, CJC-1295/Ipamorelin, tesamorelin, you name it. If you're reconstituting vials and tracking loading phases, Regimen handles it.
People on TRT. Clinic protocol or self-managed, it doesn't matter. Tracking injection frequency, dose amounts, and how you feel over time matters either way. Regimen logs testosterone, HCG, and enclomiphene protocols side by side.
People on GLP-1 medications. Semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro, Zepbound), and retatrutide all follow specific titration schedules. Regimen tracks your dose progression and reminds you when it's time to inject.
People running more than one of those at the same time. This is the big one. A lot of people are on TRT and peptides simultaneously, or running a GLP-1 alongside a peptide protocol. Most tracking apps only cover one category. Regimen covers all three.
What Can You Track?
Regimen has compound-specific tracker pages for 17 different compounds. Each one is tailored to how that compound is actually used.
GLP-1 Medications
- Ozempic (semaglutide)
- Wegovy (semaglutide)
- Mounjaro (tirzepatide)
- Zepbound (tirzepatide)
- Semaglutide (generic/compounded)
- Tirzepatide (generic/compounded)
- Retatrutide

The Free Calculators (No Download Needed)
The Regimen website has 14+ calculators that run in your browser. No account, no download, no paywall. These are the same tools people share in peptide and TRT forums because they actually solve the math problems that trip people up.

How Regimen Compares to Other Tracking Apps
Most tracking apps focus on one category. Regimen is one of the few apps that covers peptides, TRT, and GLP-1 medications in a single app. The other difference is the free calculator suite on the website.

Key Features
Injection Logging
Log every injection with the compound, dose, units, injection site, and timestamp. The app keeps a running history so you can look back at your protocol over weeks or months.
Injection Site Tracking
Regimen tracks where you've been injecting and helps you rotate sites properly. No more guessing which side you hit last time.
Smart Dose Reminders
Set reminders based on your actual protocol schedule. Weekly testosterone, twice-daily BPC-157, weekly semaglutide titration steps. The reminders match how these compounds are actually dosed.
Protocol Logging
Track your full protocol over time: what you're running, when you started, dose changes, and how you're responding.
Side Effect Monitoring
Log side effects alongside your doses so you can spot patterns. Did the headaches start when you increased your semaglutide dose? The data is there when you need it.
