The world's most researched mushroom for increasing endurance

At least 1,500 years ago, Tibetan herders observed that yaks would eat Cordyceps and then frolic with great energy and "passion." This encouraged the herders to experience the power of Cordyceps, which has led to it use by hundreds of millions of people over the ages. In 1993, the Chinese National Track and Field Team attributed their success in breaking three World Records in part to their use of Cordyceps.
