has any one tried any of these new ephedra products that claim to have 25mg ephedra in them. i have tried lipodrene and while it will keep me awake for days it dosent give me the same rush. zenalene was ok and thermogen 2 was ok they just didnt hit me like the old stackers did hell i stacked basic cuts and ephedrine hcl and it still wasnt the same. any help would be greatly appreciated.
