The only people who should consider this product are those that have a digital scale and can precisely measure out a safe dose of caffeine.
Using common measuring devices like measuring spoons etc. will likely result in too large of a dose.
Some caffeine powders also use an "anti-caking agent" but this doesn't change the caffeine content enough to justify being more generous with this type.
We feel that unless you are a food or beverage manufacturer, buying bulk caffeine powder isn't a wise decision unless you buy the necessary equipment needed to measure it accurately.
