Egrolean AMP contains this as one of its' actives as well caff anhydrous and chocamine. If AMP does the business for you then buy the ingredients here in bulk for less. I find this very effective stacked with chocamine but my dosages have been 5 tabs a time twice a day with chocamine (1 heaped teaspoon). For extra bite add 1/8 to 1/4 teaspoon of caffeine anhydrous. I'll give this 3.5* as I feel it could be a little more potent.
