Because the pen shrinks you — but it doesn’t care whether the weight leaving is fat or muscle. In the GLP-1 studies, roughly 25–40% of the weight people lose is lean mass. After 40, that’s the exact tissue you can’t afford to lose: your strength, your metabolism, your independence — and the thing that keeps the weight off when you stop.
The GLP-1 Muscle-Keeper is the over-40 protocol for losing fat on the pen without losing your muscle. No hype, no miracle claims — just the two levers proven to protect muscle in a deficit (enough protein and the right kind of training), made dead simple for a body with almost no appetite.
Inside the guide:
What it won’t do: it won’t build new muscle in a steep deficit, it won’t stop all lean-mass loss, and it won’t replace your doctor. It will keep far more of your muscle than doing nothing — which is what most people on the pen are doing.
