I have no idea but does guarana even have any psychadelic properties? Last time I checked guarana is a natural caffeine, which is why you can find doses like 1000mg inside energy drinks and such...
guarana is just a plant extract from the guarana seed or somethin, anyway it contains caffiene, however being an organic mixture, you cant really tell how much youre gettin. just get some plain caffiene and that way you know what youre ingesting. swallow a few hundred m.grams or snort 100-200 mg
