The Bottom Line

Regimen is the multi-compound tracking app for peptides, TRT, and GLP-1 medications. It handles injection logging, dose reminders, protocol tracking, and side effect monitoring for compounds like semaglutide, testosterone, BPC-157, and more. Free to download on iOS and Android with a premium tier for advanced features. The website also has 30 free calculators you can use without downloading anything.

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.

Pro Tip

You don’t need to be on a complicated stack to get value from the app. Plenty of users track a single compound, like their weekly testosterone injection or their semaglutide titration. The app scales from “one shot per week” to “five compounds with different schedules.”

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.

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.

Peptide Calculators

GLP-1, TRT & General

Community Insight

The peptide reconstitution calculator is the tool that gets linked most often in Reddit threads and Discord servers. People share it whenever someone asks “how many units do I draw for a 5mg vial with 2mL BAC water?” It solves that question in about 10 seconds.

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.

Pro Tip

The combination of injection logging and side effect tracking is where the real value shows up over time. After a few weeks of consistent logging, you’ll start seeing patterns that are impossible to notice when everything lives in your head.

Frequently Asked Questions

Is Regimen free?

The app is free to download on both iOS and Android, and you can track one compound for free, plus a 14-day trial. Premium unlocks multi-compound tracking.

What compounds can I track in Regimen?

Peptides (BPC-157, TB-500, MK-677, CJC-1295, ipamorelin, HGH), TRT compounds (testosterone, HCG, enclomiphene), and GLP-1 medications (semaglutide, tirzepatide, retatrutide).

Do I need to download the app to use the calculators?

No. All 14+ calculators run in your browser at helloregimen.com/tools without an account or download.

Is Regimen available on Android?

Yes. Regimen is on both iOS (App Store) and Android (Google Play).

How is Regimen different from a generic medication tracker?

Generic trackers don’t understand peptide reconstitution, injection site rotation, compound cycling, or pharmacokinetic modeling. Regimen is built specifically for injectable protocols.

Ready to track your protocol?

  • Smart reminders so you never miss a dose
  • Track weight, photos, and progress over time
  • Medication level curves for every compound

Can I track multiple compounds at the same time?

Yes. This is one of Regimen’s main strengths (available with premium). You can run a testosterone protocol, a BPC-157 cycle, and a semaglutide titration simultaneously, each with their own schedule, doses, and reminders.

Does Regimen give medical advice?

No. Regimen is a tracking and calculation tool, not a medical service. It helps you log and organize your protocol data. It doesn’t prescribe doses, recommend compounds, or replace your doctor.
