Progress is data-driven. Here’s a look at the last three bike lab tests of Olympic Rower Sophie Souwer, tracking key physiological markers from October (starting to use Stamox ) through December.
Testing Stamox supplementation
“These are the 3 test of Sophie done October (starting with Stamox) November and December.
As you can see there is a clear improvement on the lower range, and in the time she was able to spend at maximal watt.”
says Coach and Olympian Martino Goretti
Findings
VO₂max: Increase to 51 ml/kg/min.
Aerobic Threshold (VT1): Jumped to 73%—better efficiency.
We’re seeing a clear improvement at the lower end of the power curve, building a stronger aerobic engine.
Just as importantly, the time now spend at maximal wattage has increased—meaning Sophie can push harder, for longer, when it counts.
The athlete is building a strong, balanced physiological profile with room for continued growth across all energy systems.
This is the foundation we’re building for the 2026 season and beyond: World Cups, European & World Championships... and, ultimately, the road to Los Angeles 2028.

On individual results:
Performance gains are highly individual and depend on a multitude of factors, including an athlete’s training age, genetic predisposition, training plan, overall diet, and so on. This was a performance report on a single athlete, tested by themselves. The pattern of the data is highly consistent with the scientifically documented effect of beetroot supplementation, and athlete’ own results using Stamox.
