What half-life means
Half-life is the estimated time it takes for the amount of a compound in a defined system to fall by half.
Why context changes the number
Half-life can vary by model, species, route, assay method, formulation, and study design.
What it can and cannot tell you
Half-life can help explain research design, but it does not prove safety, effectiveness, legality, or a practical use schedule.
How to read claims
Treat simple half-life claims as starting points. Look for the study context and avoid translating them into human-use protocols.
