| Standard Dose | — | Research indicates 0.25 mg weekly SC for 4 weeks, escalating to 0.5 mg, then 1.0 mg, then 1.7 mg, then 2.4 mg weekly (FDA weight management protocol). Oral: 3 mg daily for 30 days, then 7 mg, then 14 mg daily. |
| Timing | — | SC injection any time of day, with or without food, on the same day each week. Oral: take on empty stomach with no more than 4 oz water, 30+ minutes before first food/drink/medications. |
| Cycle Duration | — | Long-term/continuous use. Weight regain occurs upon discontinuation (67% regain within 1 year in trials). |

Alternative electron carrier in the mitochondrial electron transport chain. Bypasses Complex I and III dysfunction by shuttling electrons directly to Complex IV (cytochrome c oxidase). Also inhibits tau aggregation, monoamine oxidase, and nitric oxide synthase. Hormetic — low doses are beneficial, high doses are toxic.
Semaglutide is a GLP-1 receptor agonist with 94% structural homology to native GLP-1, modified with amino acid substitutions and a C-18 fatty acid chain that enables albumin binding, extending half-life to approximately 7 days. Centrally, it activates anorexigenic POMC/CART neurons and inhibits orexigenic NPY/AgRP neurons in the arcuate nucleus of the hypothalamus, reducing hunger and increasing satiety. Peripherally, it slows gastric emptying, enhances glucose-dependent insulin secretion from pancreatic beta-cells, and reduces glucagon secretion, providing comprehensive metabolic regulation.
