Finish the 12-week protocol. See measurable results. Or get your money back.

What qualifies

To claim the guarantee, you need to have:

• Purchased the 12-Week Elite Protocol (the 4-tub Stack)
• Completed the full 12-week training block
• Followed the included protocol and dosing guidelines
• Measured your results against a baseline

The guarantee applies to the 12-Week Stack only. Single tubs and 2-tub bundles aren't covered — 12 weeks is the minimum window where the research shows meaningful adaptation.

What "measurable results" means

One or more of the following, measured against your starting point:

• Improved VO₂ max
• Lower heart rate at the same intensity
• Improved time-to-exhaustion or race performance
• Documented power output improvement

You don't need all four. One is enough.

Not sure how to measure? Our Watts Testing Guide walks you through a simple protocol — fixed-wattage sessions with and without Stamox, measuring the heart rate difference.

What's not covered

• Single tubs and 2-tub bundles — the guarantee applies to the 12-Week Stack only
• Results affected by injury, illness, or a significant break in training
• Orders placed more than 13 weeks ago
• Claims made without baseline data

We ask for baseline data because the guarantee is about change. Without a starting point, there's nothing to measure against. If you didn't record a baseline, take one now — the Watts Testing Guide shows you how.
