## What is StackProof?

Most people take supplements and hope for the best.

StackProof turns that guesswork into a real personal experiment so you finally know what's working, what's not, and what's worth keeping.

HOW IT WORKS

StackProof uses a simple 3-phase method used in clinical research, adapted for everyday use:

1. Baseline Phase - Log how you feel for 7 days without taking the supplement. This captures your natural normal.

2. Active Phase - Start taking your supplement daily and keep logging. 60 seconds a day.

3. Review - See a clear before vs after comparison across every metric that matters to you.

No guessing. No placebo. Just your own data telling you the truth.

WHAT YOU TRACK

Every day you log 5 metrics on a simple 1-5 scale:
- Energy
- Focus
- Mood
- Sleep Quality
- Side Effects

Over time, StackProof shows you exactly how each metric shifted from your baseline to your active phase, with a confidence rating based on your consistency.

SMART BASELINE

After your first experiment, StackProof learns your patterns. On future experiments it can detect when you have enough recent data to skip the waiting period and start the active phase immediately.

BUILT FOR REAL BIOHACKERS

StackProof is designed for people who take their optimization seriously. Whether you're testing Lion's Mane for focus, Magnesium for sleep, Ashwagandha for stress, or anything else, every experiment gives you a clean structured result you can actually act on.
