i use one equate(walmart) brand stay awake pill 200mg caffeine one two way action minithin (found at truck stops and 7-11's) contains 25 mg ephedrine hcl and 200 mg guanifesin (SP) an expectorant and one aspirin generic. cost is much less and you know you are getting the eca stack pure and simple if you want to add stuff read the labels on your fav product and add seperately save much money
When i first started using fat burners, hydroxycut and xenadrine worked fine. But after a while, like anything your body gets used to it. I've had better results using Adipokenetix and MD6. throw in a little T2 by biotest and watch your metabolism shoot through the roof.
