The shot is working. So why are your arms shrinking?

GLP-1 medications can quietly strip 25–39% of total weight lost from muscle, not fat.

Gumi is the creatine and collagen gummy built specifically to protect what you're working so hard to keep — even when you can barely eat.

Your body is losing more than fat right now.

When your appetite disappears, your body starts scavenging. Gumi gives it two things it desperately needs — at the cellular level — before it goes looking for them in your muscle.

Muscle Protection

4g of clinically dosed creatine monohydrate replenishes ATP, the fuel your muscles use first. When that runs out, your body starts cannibalising lean mass.

Energy without eating

Creatine delivers cellular energy that doesn't require calories. On the days you can barely face food, your muscles still get what they need.

Skin Firmness

2g of collagen per serving supports the structural protein that keeps skin taut as the fat underneath it disappears. Less deflated. More defined.

Actually Takes It

94% of Gumi users stay consistent — because three gummies before bed is something you can do even when a protein shake makes your stomach turn.

Nobody warned you about the part that comes after the weight loss.

GLP-1 medications work by making you not hungry. That sounds like a gift. Until you realise your body still needs fuel — and if you can't eat enough to provide it, it takes what it needs from somewhere else.

39%

Of total weight lost on GLP-1 medications can come from muscle mass — not fat — according to research cited in peer-reviewed weight loss literature. That's not a side effect. That's a structural problem.

60%

Of the body's creatine stores are depleted daily through normal activity. On a GLP-1, when you're eating next to nothing, that depletion goes unreplenished — and your muscle cells pay the price first.

Every GLP-1 protocol says "take creatine and collagen." Most just don't tell you how.

When you're barely eating, choking down powder and forcing a protein shake is not a plan. It's another thing to fail at. Gumi is built for the reality of life on a GLP-1.
