My name is Shayne Autry, I have been a martial arts instructor/competitor for over 25 years. My father and fI ounded the Dallas Academy of Martial Arts. Over the years, I along with my students we have tested and used countless training methods and sport supplements to improve the training performance in martial arts. Based on my students feedback and my personal experience the striking effect about Tribustol is when it “kicks in”-you really feel the effects! The increased energy helps sustain longer and more precise workouts. Additionally it makes you feel good so your desire to workout is improved. I can say-truthfully Tribustol is the most effective sports supplement we at the Dallas Academy of Martial Arts have ever used we stand behind it!
