World’s only cortisol stress reducer with immediate effect
KA-EX is proven to reduce stress hormones within 48 hours, aiding crucial post-workout recovery. Cortisol stress from workouts, caffeine, stress, and lack of sleep leads to muscle loss, belly fat, weak immunity, and sleep issues. Lowering cortisol maximizes training outcomes, boosts muscle growth, endurance, and day-to-day energy, while reducing muscle soreness (DOMS).
