Myo vs Regimen

The Myo Alternative to Regimen

Download on theApp StoreMuscle-first tracking. Free core. Private by design.

Regimen is a well-built tracker for GLP-1s, peptides, and TRT, with a polished app on both iOS and Android, dose calculators, and pharmacokinetic modeling that shows where your medication levels sit over time. If you want a broad protocol manager that handles a wide stack of compounds, it's a serious option and we'll say so plainly.

Myo takes a narrower, deeper stance. It's muscle-first: the whole product is organized around the question Regimen doesn't really center, which is whether the weight you're losing is fat or lean mass. For people on GLP-1s specifically, that framing changes what gets measured and surfaced day to day.

This page is an honest side-by-side. Where Regimen is genuinely strong, we say so; where Myo is built differently, we explain why it matters - especially around body composition, compounded-vial support, and keeping the core free.

What Regimen does well

  • Mature cross-platform app available on both iOS and Android
  • Broad compound coverage across GLP-1s, peptides, and TRT in one place
  • Built-in dose calculators and pharmacokinetic level modeling
  • Polished protocol and schedule management for complex stacks

Where Myo is different

Muscle-first by design

Myo is organized around fat-vs-muscle, not just dose logging. Protein targets, resistance-training streaks, and body-composition trends sit at the center of the app, so muscle loss on a GLP-1 shows up as a pattern instead of a surprise at the next DEXA scan.

Free core, no paywalled basics

Logging your doses, injection sites, and side effects is free in Myo. The essentials of safe tracking shouldn't sit behind a subscription, so the core stays open and the muscle-first analytics are the upgrade, not the basics.

Built for compounded vials

Myo treats reconstitution, units-to-mg conversion, beyond-use dates, and vial longevity as first-class features - the exact math compounded GLP-1 users do every week, handled in-app rather than on a notes-app scratchpad.

Named medical reviewer

Myo's health content carries a named medical-reviewer byline and clear update dates - an E-E-A-T trust signal that many trackers, Regimen included, don't surface.

Regimen alternative FAQ

Is Myo a good Regimen alternative?

If your priority is keeping muscle while losing fat on a GLP-1, yes - Myo is built muscle-first, with body-composition and protein tracking at its core and a free tier for the basics. If you need broad multi-compound protocol management across iOS and Android today, Regimen is the more mature all-rounder. They optimize for different things.

Does Myo do pharmacokinetic dose modeling like Regimen?

Yes. Myo's medication-level visualizer plots where you are on your medication's curve between doses, factoring in the ~7-day semaglutide and ~5-day tirzepatide half-lives. The difference is Myo pairs that with muscle and body-composition tracking rather than treating dose levels as the whole story.

Is Myo available on Android like Regimen?

Myo is on iOS. Regimen is on both iOS and Android, so if Android availability today is non-negotiable, that's a fair point in Regimen's favor - we'd rather tell you that than pretend otherwise.
