yeah i used it before it helps but it easier with the chewables, and it did wonders when compund it with hydroxy cut or xenadrine, you still gotta do cardio but after the 2nd or 3rd day youll feela differnce i did, you sweat alot and get major pumps try it the injectables hurt too much, i went up to 5 grms a day since there really isnt any side effects
