There's reportedly even research which suggests it has potent anti-cortisol actions, thereby preventing the muscle breakdown effects of stress and overtraining.
Tribestrone® is usually found in combinations of 300 mg of Tribulus, 100 mg of Mucuna and 100 mg of ashwagandha.
Ciwujia
Although muscle has the capacity to use the three primary nutrients, protein, carbohydrate, and fat for fuel, it is the balance of carbohydrate and fat utilization during exercise that largely determines exercise performance and duration. With the exception of extreme intense exercise of short duration, the body uses a combination of carbohydrate and fat for fuel.
At lower exercise intensity and longer duration, fat can become the primary energy source. This in no way minimizes the critical role of carbohydrates. The importance of carbohydrates is underscored by the fact that depletion of the intramuscular stores of carbohydrate is almost always associated with muscular exhaustion.
Much of the work concerning energy utilization during exercise was conducted in the high-performance athlete. However, it is clear that the application of these findings may be extended to benefit any individual who exercises regularly to maintain weight or optimize physical performance.
An herb tested and proven in the exercise physiology laboratory that could safely enhance performance by optimizing energy utilization during exercise would offer enormous benefit to both the serious and the recreational athlete.
Ciwujia (su wah ja), a natural root grown in the northeast section of China, has been used continuously as part of traditional Chinese medicine for almost 1700 years. The usual human dose is 9 to 27 grams per day of the raw herb. Ciwujia has been shown to be remarkably safe. It has been administered to laboratory animals in multiple studies, at doses ranging from 60 to 200 times the recommended human dose. Ciwujia does not contain caffeine and does not produce any stimulant or anabolic steroid side effects.
Ciwujia has been used in traditional Chinese medicine to treat fatigue and to bolster the immune system. This root intrigued researchers because of published reports of its use by
