| What users compare it for | Preclinical: selective elimination of senescent cells. No proven human benefit. | Preclinical: improved insulin sensitivity, metabolic regulation, exercise performance in mice. | Longevity/circadian claims; telomerase association not established as fact. |
| Onset timeline | Mouse outcomes assessed over days to weeks, depending on tissue model. | Metabolic endpoints assessed over days to weeks in mice; exercise performance improvements after ~10 days. | Often marketed as weeks-long courses; treat as hypothesis. |
| Main tradeoff | Potential upside comes with much more safety and screening caution than lower-risk alternatives. | Potential upside comes with much more safety and screening caution than lower-risk alternatives. | Potential upside comes with much more safety and screening caution than lower-risk alternatives. |
