| How it works | Long-acting agonist of the GLP-1 receptor (GLP1R) — a G-protein-coupled receptor in the pancreas, hypothalamic appetite centres, and vagal afferents. Activation is glucose-dependent: stimulates insulin, suppresses glucagon, slows gastric… | Raises blood bicarbonate, increasing the extracellular pH buffer that pulls H⁺ out of muscle — the extracellular complement to beta-alanine's intracellular buffering. |
| In plain English | It copies a gut hormone that tells your brain "I'm full." Hunger and constant food-thoughts fade; you eat less without willpower. STEP trials: ~15% bodyweight lost in 68 weeks. | Baking soda makes your blood better at soaking up the acid your muscles dump during hard effort, so you last longer. The catch is it can wreck your gut. |
| Bottom line | The most powerful weight-loss drug in history until tirzepatide/retatrutide. | Real ergogenic for repeated sprints; stomach tolerance is the limiter. |
| Availability | Prescription only | Available over the counter |
