How the product works
14 questions. One personal protocol.
Assessment → priorities → check-ins → direction.
- 01
Answer 14 questions
Set the personal state and age context behind your Starting point.
- 02
See three layers
Starting stays fixed. Base adapts. Today moves.
- 03
Get your priorities
Begin with four Core rows and personal priorities.
- 04
Check in
Log daily, weekly, and periodic actions in place.
- 05
Watch direction
Compare D30–D365 paths and build real history.
The Home view
Today and Base, with the context that matters.
Today and Base sit above a 0–1100 scale for Starting, Age Median, Base, and Maximum Potential. Today is not duplicated on the scale.
Your first protocol
Four Core. Priorities only when relevant.
Sleep, Resistance Training, Diet Quality, and Life Stress form the fixed foundation. Body Composition or Alcohol appears only in the role supported by the profile.

Body CompositionPersonal Priority
This example includes Body Composition as a periodic Personal Priority. It is not a fifth Core action or a daily task.
36 Advanced optimizations
Go deeper, deliberately.
The catalog ranks positive modeled candidates for the current protocol and can mark up to six as Recommended for You—without imposing an add limit.
Twelve factors have direct models with separate Today-only and chronic behavior; the rest never receive an invented numerical contribution.

The Dr. Testo Method
Personalized. Research-mapped. Time-aware.
Versioned logic separates Starting, adaptation, daily signals, fit, headroom, and scenario assumptions—then ranks the next actions.
Local-first by design.
Assessment, calculation, check-ins, protocol, and history stay centered on the device without a custom account dependency.

Dr. Testo Learn
Learn what shapes your protocol
Clear guides explain each factor, show the evidence context, and connect reading to the right place inside the product.
Sleep
Sleep and testosterone: what the evidence suggests
A practical look at sleep duration, sleep timing, and why Dr. Testo treats recovery as a core input rather than an isolated score.
Read guideTraining
Resistance training and testosterone: where it fits
Understand why resistance training is always present in Dr. Testo's Required Core and how the app separates action from exaggerated promises.
Read guideStress
Stress and testosterone: tracking a changing signal
See how life stress can be represented as a changing signal and why Dr. Testo distinguishes today's context from a longer-running pattern.

What the product is — and what it is not
01Is Dr. Testo a generic habit tracker?+
No. Its navigation, model, protocol, and progress system are built specifically around estimated testosterone direction.
02Do I choose my Core actions?+
Four Core actions form the fixed foundation. The model adds Personal Priority rows only when the profile supports them; Advanced remains optional.
03What is the difference between Base and Today?+
Base represents the slower-moving chronic direction. Today adds current, temporary signals on top of Base.
04Does every Advanced factor show a numerical effect?+
No. Only factors with a direct model can show a counterfactual number. Other curated factors remain clearly marked as tracked or unmodeled.
One system, not another advice list
Turn the next useful action into a protocol you can actually follow.
