How the score works
Five inputs. One score. A real protocol.
- Chronological age — the baseline. We compare your biological age estimate against this.
- Sleep, energy, stress — the three lifestyle signals with the most actuarial weight in aging research.
- Recovery + exercise frequency — separate axes. You can train daily and still recover slowly; the stack changes accordingly.
- Primary concern — drives the core 2-3 picks. Skin / energy / cognition / body comp / recovery / cellular health.
- Budget + experience — sizes the stack so it fits and doesn't overlap with what you already run.
The score is directional, not clinical. Don't make medical decisions off it. Talk to a doctor before changing your protocol. Stacked is a research-intelligence platform; the quiz exists to help you orient inside the catalog faster.
