Gives a nice buzz
It gave me a nice buzz which coffees no longer provided me due to years of caffeine intake.  I was looking for more caffeine than coffees have becuase I built up tolerance to caffeine from many years of caffeine.  You have to fight thru a grainy bad taste, but if you are looking for something that will give better effect than coffees, I suggest this.  Must boil water first then pour that onto a teaspoon or more of this.  Dont add it to cold water - not soluable & that just makes a mess.  This brand was no problems, vs I tried a different brand Ameriherb sold by Wendy's Herbs which gave me diarrhea.
