Gassed early

Training hard, recovering slow.

Stress and poor recovery cap your output before your muscles do. By supporting the stress and recovery side of training, an adaptogen helps you show up for the next session.

How KSM-66® helps

Built for performance.

Endurance & VO₂max

Trials link the 600 mg serving to improved VO₂max and time-to-exhaustion. More in the tank when it counts.

Strength & recovery

Resistance-trained subjects on KSM-66® saw greater strength gains and lower markers of exercise-induced muscle damage.

Recovery is built on calm

Lower stress supports better sleep and recovery, the unglamorous base that actually drives adaptation.

+13%

In a trial of healthy athletic adults, 600 mg/day of KSM-66® was associated with a significant increase in VO₂max (a key marker of cardiorespiratory endurance) versus placebo.

PR'd my half marathon.

Training while building a company. I expected to be wrecked by week 8. Instead I PR'd and recovered faster than ever.
