Hi my name is Gene Bischoff a member of NOTC, 15 th Street Flyers and the Chalmette Track Clubs. I have been running for over 20 yrs. In recent years I have had two accidents causing me to have two knee surgeries and a foot ailment misdiagnosed by 4 doctors. I am happy to say that I am once again running full speed and pain free aided by the use of your product 4D. Since using your product for the last 4 months I have lost weight and gained lean muscle that I never thought possible. Also the energy your product provides have helped me reduce my times to Pre-Katrina levels all without any pain in my knees. I highly recommend your product as a testimonial to my excellent results using it. Thanks 4D.
