Superior Nutrient Absorption

Key Ingredients

Our formulas are made with clean, natural ingredients, with clinically-validated dosages to support health and performance.

Peak02™ (Adaptogenic Mushrooms)

2,000 mg

Clinically studied mushroom blend that enhances VO2 max, endurance, and oxygen utilization during exercise.

Peak02™ (Adaptogenic Mushrooms)

Epicatechin (from Green Tea Extract)

150 mg

This green tea constituent is a putative myostatin inhibitor thought to promote muscle hypertrophy.

Epicatechin (from Green Tea Extract)

elevATP®

150 mg

A patented blend of ancient peat and apple extracts for boosting the body’s production of cellular energy (ATP).

elevATP®

AstraGin®

50 mg

A blend of adaptogenic herbs that improve nutrient absorption and support muscle recovery.

AstraGin®

Peak02™ (Adaptogenic Mushrooms)

2,000 mg

PeakO2™ is a comprehensive blend of six adaptogenic mushrooms, namely Cordyceps, Reishi, King Trumpet, Shiitake, Lion’s Mane, and Turkey Tail. These mushrooms collectively enhance the body's ability to adapt to both physical and mental stressors, including high-intensity and long-duration exercise.

Clinical research has demonstrated that PeakO2™ significantly improves oxygen utilization and increases time to exhaustion, both key factors for athletes looking to push beyond their current performance limits [1]. 

Other research has shown improvements in VO2 max, anaerobic threshold, and perceived exertion in participants supplementing with PeakO2™ [2]. Thus, taking PeakO2™ can lead to marked performance enhancements in as little as 7 days.

Peak02™ (Adaptogenic Mushrooms)

Epicatechin (from Green Tea Extract)

150 mg

Epicatechin is a naturally occurring flavonoid predominantly found in cocoa and green tea leaves. Renowned for its potent antioxidant properties, epicatechin has garnered significant attention for its role in muscle physiology. One of its key functions is the inhibition of myostatin (growth and differentiation factor-8), a protein that negatively regulates muscle growth [3]. Furthermore, it activates adenosine monophosphate-activated protein kinase (AMPK), which is instrumental in energy homeostasis, thereby promoting lipolysis, fatty acid oxidation, and improved glucose uptake in muscle tissues [4].

Epicatechin aids in nitric oxide production, a critical factor that enhances vascularity and blood flow [5]. Improved blood flow ensures more effective nutrient delivery to muscles during physical exertion, leading to optimized muscle performance and recovery [6]. Collectively, these benefits make epicatechin a valuable addition to muscle-building and performance-enhancing regimens.

Epicatechin (from Green Tea Extract)

elevATP®

150 mg

elevATP® is a natural combination of ancient peat and apple extracts designed to increase the production of adenosine triphosphate (ATP), the body’s primary energy currency. This blend leverages the synergy of its components to stimulate endogenous ATP production, thereby enhancing cellular energy availability. ATP, a pivotal molecule in energy transfer within cells, is essential for muscle contractions, nerve impulse propagation, and chemical synthesis.

Supplementation with elevATP® has been demonstrated to increase intracellular ATP levels, leading to improved strength, power, and performance during high-intensity exercise. Notably, elevATP® enhances mitochondrial efficiency and supports the physiological demand for energy during strenuous physical activities. Additionally, research suggests that elevATP® may play a role in delaying the onset of muscle fatigue, thus extending workout durations and intensities​​.

elevATP®

AstraGin®

50 mg

AstraGin® is a patented blend of Astragalus membranaceus and Panax notoginseng. Research shows that AstraGin® can increase the absorption of various nutrients, including amino acids, vitamins, and minerals, thereby supporting overall health, energy levels, and performance [13].

AstraGin®

SenActiv®

50 mg

SenActiv® is an adaptogenic blend of Panax notoginseng and Rose hips extracts designed to promote muscle energy and recovery. The bioactive constituents of these herbal extracts work by enhancing the regeneration of muscle cells and mitigating inflammation, thereby facilitating quicker recovery times and improved muscle endurance.

Research indicates that SenActiv® can significantly improve muscle recovery, reduce muscle damage, and support overall exercise performance. Studies have demonstrated that individuals supplementing with SenActiv® experienced decreased levels of exercise-induced muscle soreness and markers of muscle damage, such as creatine kinase. Moreover, the anti-inflammatory properties of SenActiv® contribute to the maintenance of healthy muscle tissue, reducing the risk of chronic injuries that could impede athletic progression.
