You know the shot can cost you muscle.

Researchers found that a meaningful share of the weight lost on these medications can be lean mass.

1 in 4

pounds lost on a GLP-1 isn’t fat.1

And muscle is a big part of that.

Reviewers have compared the lean mass lost on a 16-month course of GLP-1 treatment to roughly

20 years

of natural aging.2

Nobody’s watching it.

51%

of prescribing physicians in a 2025 Sermo poll said the risk of muscle loss on these medications “warrants better follow-up”.3

Yet, almost nobody is set up to monitor it. A check-in was built to manage your dose and side effects, not to measure your muscle.

Many people on a GLP-1 get little exercise or nutrition guidance for keeping their strength and muscle.4

Orvi Systems are built to protect muscle while the weight comes off, and support muscle growth when your body’s ready.

More muscle means more from life.

  • The more muscle you have, the easier you’ll find everyday tasks.
  • Climbing the stairs. Carrying the groceries. Playing with the grandkids.
  • It all gets easier.

Without muscle, lighter can also mean weaker.

An ordinary day, done right.

  • Yesterday was hard, but you still managed to hit your protein target.
  • You feel yourself getting stronger from the weekly strength sessions.
  • You button up your old skinny jeans without having to suck in your stomach.
  • You catch your reflection in the mirror. You’re proud of how you look. Not just smaller. Toned.

2-year warranty on manufacturing defects

From two brothers who watched it happen.

Henry and Jackson Ellison with their mom

Our mom lost 56 lbs on her GLP-1. By month 4, the jeans she’d kept for 15 years fit again. Everyone told her she looked amazing.

She didn’t feel amazing.

7 months in, her physical therapist re-ran a test from the spring. She had lost close to half the strength in her legs.

She’d done nothing wrong. Neither had her doctor. He only had 10 minutes at her check-ins.

Everybody had warned her about the muscle. She had no idea what to actually do about it. And nobody had measured it.

So we built the plan she never got, and a way to see whether it’s working. We wish she’d had both on day 1.

Good. That’s exactly what 4 major medical organizations recommend for people on a GLP-1: more protein, resistance training, and tracking your body composition.4 Fewer than half of people on these medications reach the protein target that protects muscle.5 The Protect System is built for the days you have to make yourself eat.

You don’t have to become one, if you don’t want to. The medical advisories say resistance training, not a gym membership. The Protect System’s sessions run at home, 3 times a week, in about 30 minutes, with a 20-minute version for harder days. The Grow System is there if and when you’re ready to progress.

A little, on every scale, and you’ll see it early. Watch the 7-day trend, and give it about 2 weeks. The trend, alongside the strength tests in the systems, is all you need to track your progress.

No. Every system is written for any 8-electrode scale, a tape measure and a sit-to-stand test. The Orvi Body Scan is the recommended instrument, and you can add it to any system.

It’s designed for the realities of eating and exercising on a GLP-1, whichever one you’re on: Ozempic, Wegovy, Mounjaro, Zepbound or another.

The Protect System and the Grow System come with a 60-day guarantee, the Protect & Grow System with a 100-day guarantee, counted from delivery. If it isn’t for you, email hello@getorvi.com and we’ll organize a refund, and you keep the files either way.

Protecting muscle now costs less than building it back later.

Already months in, or stopping soon? It’s never too late to start protecting your muscle.
