Personal state
Fifteen answers establish factor state, age context, and the immutable Starting origin.
The Dr. Testo Method
Personalized science, translated into action.
Research-mapped factors, layered mathematics, and your own input state work together to rank a protocol and show direction over time.

Inside the calculation
Layered math, without a black-box score
The exact coefficients stay protected, but the logic is visible: what enters, how it changes over time, where limits apply, and which scenario is being compared.
Change, not double count
Core movement is measured against the onboarding state rather than awarding the same association twice.
Factor-specific time
Sleep, body composition, stress, botanicals, and environment can adapt at different speeds.
Fit, caps, and headroom
Evidence, estimated fit, shared limits, and remaining modeled room constrain each contribution.
Named scenarios
Current, Core, Selected, and Full paths run through the same versioned engine at explicit checkpoints.
Model flow
Inputs move through defined layers
The calculation core is deterministic and versioned. Product rules, evidence mappings, adaptation, and scenario choices are kept separate so the same input does not quietly count twice.
Assessment state
The required questionnaire establishes the initial factor state and Starting point.
Chronic adaptation
Longer-term adherence moves Base gradually toward the internal equilibrium direction.
Daily signals
Current inputs contribute to the Today view without rewriting the historical Starting point.
Scenario paths
Current, Core, selected Advanced, and full-potential paths use explicit assumptions at named checkpoints.

Three public values
Starting, Base, and Today are intentionally different
Starting is historical
Created once at activation and preserved across future model epochs.
Base is adaptive
Moves with chronic state, adherence, and time — not with every isolated check-in.
Today is relative
Shows acute signals around Base for the current local day.
Evidence mapping
A curated factor is not automatically a numerical factor.
Each supported factor carries a product role and an evidence record. Directly modeled factors can generate counterfactual contributions. Other useful factors can be tracked without manufacturing a number. Missing data stays unknown instead of becoming an automatic penalty.
Projection logic
Scenarios are comparisons, not promises.
Protocol Potential separates Current Habits, Core Protocol, Core plus selected optimizations, and Full Optimization Potential. D30, D60, D90, D180, and D365 are checkpoints on those assumptions, while Progress remains the record of real use.

Reference context
A shared scale makes position legible.
The product uses a harmonized 264–916 ng/dL healthy reference band for non-obese men aged 19–39 as a benchmark context. It is not presented as a universal laboratory range or a personal maximum. The visual display extends to 1100 ng/dL.

Healthy reference benchmark
Versioned and inspectable
The model can evolve without silent rewrites.
The accepted numerical baseline, bundled configuration, schema, and source checkpoint are recorded separately. A new product model requires a new version, regression checks, simulations, and explicit acceptance — not a hidden marketing adjustment.
Use the model to choose direction; use your history to see what happened.
Dr. Testo keeps projected scenarios and recorded progress side by side without pretending they are the same kind of evidence.
