It has long wanted to order this product, I decided to test the training camp, hosted by two -one tablet 20 minutes before your workout. the first few days did not feel the difference, but then the results began to improve, especially in the race, added to 10-15 percent of the time, and a lot easier, more energy. The only negative - it is the smell, so that close tightly cover, will definitely book again! The best of what I have tried! If the review was useful, click the EU pzhl;) Happy shopping! (:
