Don’t Just Feel the Difference—Measure It

Validate the impact of Rapsyn stacks with our structured self-testing protocol to quantify your cognitive gains.

Download Testing Protocol

1. Establish a Baseline (1–2 Weeks)

Journal daily on a 1–10 scale for focus, mental energy, mood, and sleep quality. Use tools like Cambridge Brain Sciences or Quantified Mind for cognitive testing 2–3 times weekly.

2. Introduce Core Foundation (4–6 Weeks)

Start with the Core Foundation stack. Continue journaling and cognitive testing. Compare results to your baseline for significant trends.

3. Washout Period (1 Week)

Stop the stack to return to baseline, confirming supplement effects.

4. Add a Module (4–6 Weeks)

Restart Core Foundation and add one module (e.g., Executive Focus). Track and compare results to baseline and Core-only periods.

5. Analyze and Iterate

Build a personalized regimen by systematically testing each component to find what works for your neurochemistry.
