Thermo Cadio System??? Please Help this Noob

Alrighty I purchased some GNC Thermo Cardio System today...It supposed to Increase Calories burned before exercise by 70%..Calories burned during exercise by 8% and calories burned after exercise by 60%.   It got its claims from a double blind placebo experiment. Im wondering if anyone else here has tried it out. Im tryin to drop about 10 pounds and figured this might help......It says on the directions to take 30-60 min before lunch or dinner so im guessin i should take the serving 30 min before lunch...eat lunch..wait another 45min for the food to digest and then hit the gym? aight well hit me up if ya know anything about this stuff. if i dont see any results in 10 days then i just return it. I know 10 days really isnt that long of a time but i dont care i usually dont fool around with weightloss type pills
