| Standard Dose | Research indicates Dasatinib 100 mg + Quercetin 1000-1250 mg orally for 2 consecutive days, repeated every 2-4 weeks (intermittent 'hit-and-run' dosing). | — |
| Timing | Take both compounds together on dosing days, with or without food. The 'hit-and-run' approach exploits the fact that senolytic effect occurs rapidly but senescent cells take weeks to re-accumulate. Quercetin bioavailability is improved by fat co-ingestion. | — |

Dasatinib is a multi-kinase inhibitor (targeting SRC, ABL, c-KIT, PDGFR, and ephrin receptors) originally developed for chronic myeloid leukemia. Quercetin is a natural flavonoid that inhibits PI3K, serpine/PAI-2, BCL-xL, and other anti-apoptotic pathways. Together, they constitute a senolytic combination that selectively induces apoptosis in senescent cells by disabling the senescent cell anti-apoptotic pathways (SCAPs) that allow damaged, non-dividing cells to resist programmed cell death. Senescent cells accumulate with aging and secrete the SASP (senescence-associated secretory phenotype) — inflammatory cytokines, matrix metalloproteinases, and growth factors that drive tissue dysfunction. By clearing senescent cells, D+Q reduces SASP-driven chronic inflammation.
