Push The Envelope.

Peak O² was specifically designed to help users adapt to and overcome both physical and mental stress, resulting in improved power output and performance.

This product carries out its performance-enhancing effects by improving oxygen utilization and work capacity while simultaneously reducing lactate levels.  When you buy Peak O², you can train harder for longer.

Suggested Use:

Research suggests that Peak O² is best taken pre-workout for acute performance benefits, but it also builds up in the system over time.

Pre-Workout (30-60 minutes before exercise). Improves oxygen utilization, endurance, and VO₂ max.

Daily use of Peak O² has cumulative effects, so taking it consistently (even on rest days) enhances endurance, power output, and recovery over time.

Improve Oxygen Utilization.

Peak O² is an organic-certified combination of 6 adaptogenic mushrooms that are grown in the United States, including:

Cordyceps (Cordyceps Militaris) – Known for boosting energy, endurance, and oxygen efficiency. This mushroom helps support your body’s natural ATP production, delivering more energy for longer workouts.

Reishi (Ganoderma Lucidum) – Helps reduce fatigue and improve overall vitality. Reishi is known for its ability to enhance the body’s response to stress and improve recovery times.

King Trumpet (Pleurotus Eryngii) – A potent mushroom that supports cardiovascular health and aids in muscle endurance. It also helps combat oxidative stress and supports better lung function.

Shiitake (Lentinula Edodes) – A well-rounded mushroom that helps improve immune function, support muscle endurance, and enhance overall energy levels.

Lion’s Mane (Hericium Erinaceus) – Famous for its cognitive benefits, Lion’s Mane also supports nerve growth and mental clarity, helping you stay focused during physically demanding workouts.

Turkey Tail (Trametes Versicolor) – Known for its gut-supporting properties, Turkey Tail enhances immune function and promotes overall well-being, allowing your body to recover faster from intense physical exertion.

Studies have shown that Peak O² appears to improve submaximal endurance performance. When supplementing with up to 2g/day, blood lactate levels have been shown to decrease by 9% when subjects train at the same work rate. This essentially indicates that taking it helps your body exert less stress to meet the demands of exercise.
