Pick Starbucks Doubleshot Espresso & Cream when you want the lighter dose or a slower ramp, and Super Coffee when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.
