EnduroBoost contains 3 Adaptogens, Rhodiola Rosea, Eleutherococcus senticosus, and Schisandra Chinensis, which come from a specific family of herbs that grow in some of the earth’s most extreme climates. These herbs have individually been used for centuries in Asian and Scandinavian countries, and they have even been given to astronauts to help them deal with the stresses of space travel. Now we’re not saying this unique, certified drug-free combination is going to launch your athletic career to the moon, but we do expect it will help you break your boundaries.
