This product is probably the strongest out there, without the jitters. It has 300mg of Caffeine and 50mg of Ephedra Extract, 100mg of Synephrine HCl, 1,3-dimethylamylamine at 25mg, Yohimbe at 5mg and your adrenaline sensitizing complex includes L-tyrosine, Schizandra, Licorice Root at 200mg. The cool thing about this product is that it also helps stop the build up that you get when you take other ephedra products. So the longer you take this you don't feel anything less than the first time you took it! We have had a number of people that have switched to using this product because the other ones just don't work as well as the first time they took them. It usually takes about a week on this to clean of the receptors from the other products, I think thats why it is such a good seller. This would be the Gold Formula!
