I got both. During the study, none of the personnel knew which was which. When the study was over they confirmed that my suspicions were correct. The sensation I experienced with the juice was an increase in blood flow to my upper body as if I had done a mild workout with dumbbells. I had to complete walking tests and tests on a recumbent bicycle while they measured my VO2 intake. Sorry, I can't share any more information about the study at this time.
