## Elimination Kinetics & 97% Washout Benchmark for Berberine vs Semaglutide (Ozempic)

- **Documented Elimination Half-Life (T½):** Berberine: 4-6 hours; Semaglutide: 168 hours (7 days)
- **Steady-State Equilibrium Window:** Achieved after 4.0 to 5.0 consecutive half-lives of regular administration.
- **97% Systemic Washout Threshold:** Requires 5.0x elimination half-lives following final dose administration.
- **Optimal Administration Schedule:** Berberine: 500mg with 3 daily meals; Semaglutide: once weekly subcutaneous
