VO₂ MAX INCREASE (4 MO)
LOG // THOMAS E. // X2 NATIONAL ROWER CHAMP

VO₂ Max 72.1 → 76.6

"Stamox’s impact on my VO₂ max is undeniable. My increase from 72.1 to 76.6 in just four months is highly unlikely through training alone."

POWER OUTPUT JUMP
LOG // JACK B. // ULTRA DISTANCE RECORD HOLDER

+2.6% Threshold Elevation

"I re-tested my 12-minute max and saw a 2.6% increase from 448W to 460W—a serious performance jump. Testing also showed near-zero heart rate drift as fatigue set in."
