How checks are made
- 01
Each compound shows its dose basis: a published cohort, an FDA label, or a guide-modeled community pattern.
- 02
Contraindications filter compounds against a published health-history list before any output renders.
- 03
Computation runs in your browser. The engine is deterministic; the same inputs always produce the same protocol.
