BulkSupplements Guarana Extract (22% Caffeine) Powder - 800mg per Serving - 100 Grams (3.5 oz) - 125 Servings

I was making my own "lit teas" by using caffeinated flavored beverage packets but switching to Guarana allowed me to regulate the amount of caffeine I put in a drink and not need to use caffeined sink packets. Only 1/4 tsp is 200mg of caffeine and it's flavorless (as far as I can tell). Great value; this is going to last a long time.

This stuff is pretty great! A “natural” caffeine, awesome! I make my own syrups for sodas, and this stuff really helps when I make a quart or two of ‘mountain dew' syrup or coca cola syrup. I tried it in a sprite syrup I made and the flavor came thru and was not that good, but that was my fault! So, YES, I would definitely recommend this stuff, especially if you want a natural pick me up!

It does exactly what it says. I take it in my coffee. It's easier to mix it in a hot coffee, otherwise it's hard to dissolve.

I've been on and off this product for years it works great before a workout

I actually purchased this for someone else they haven't made any complaints about it so I guess it works.
