Coffee's caffeine content has been tested and if you're looking strictly for the bigger doses of caffeine, you may want to hit the convenience store instead of your barista.  Testing firm, Labdoor, tested medium size coffee sizes from four national coffee chains: Starbucks, 7-Eleven, McDonald's and Dunkin Donuts.  What they found is that different coffee brands do contain different amounts of caffeine.  The research found 7-Eleven had the highest caffeine count with 280 milligrams (mg) per cup, followed by Starbucks with an average of 267 mg, McDonald's McCafe had 227 mg, and Dunkin' Donuts with 220 mg per cup. However statically, it is a pretty even amount per store as each brewed batch of coffee varies (Although Starbucks has the most consistency).  The report found that adults between the ages of 40 and 59 were the biggest consumers of coffee, drinking an average of 410mg per day.  The FDA guidelines for caffeine consumption is 400mg/day.
