Built forGLP-1 Users

Don't Sacrifice The Marginal Decade.

The Number That Matters

5g creatine + 22g protein

the muscle-preservation pair every GLP-1 user should be taking

Why this protocol exists

Attia's Marginal Decade thesis: the muscle, strength, and aerobic capacity you carry into your fifties is the muscle, strength, and aerobic capacity you draw down for the next forty years. There is no muscle bank to refill once it's gone.

GLP-1 medications accelerate the withdrawal. Up to 39 percent of the weight you lose is fat-free mass. Sarcopenia of aging compounds it. Resistance training is necessary but not sufficient — you can't train muscle you don't have the protein to build.

The SQ[1] Starter is the smallest possible defense: Protect (22g whey isolate, the clinical 1.6g/kg/day enabler) and Strengthen (5g creatine monohydrate, consensus dose for retention). Two products, one decision, one priority — the muscle that gets you to 100.
