One bar of this soap contains approximately 12 servings/showers per 4 ounce bar with 200 milligrams of caffeine per serving. The price per bar is $6.99 and they promise that showering will give you a “jolt” of energy. So, if you don’t have time for coffee, but still want the effect, this is your solution. Would this change the definition of the phrase “We should go grab a coffee sometime”?
