this jerky is OK, but it doesn't make me jittery enough

Since the dawn of time, man has sought to combine stimulants with well, everything. From the coca leaves included in CocaCola to Sparks Energy Drink, folks have always been looking for ways to get up to get down. This brings us to the latest incarnation of this age old quest: PerkyJerky

"Perky Jerky caffeinated beef jerky is the world’s first performance enhancing meat snack. Put simply, we’ve combined the most tender and flavorful beef jerky, with an extra dose of energy (caffeine, from the Guarana we add) to provide a jerky experience you won’t find anywhere else.

Whether you love it because it’s the best tasting jerky around, or because it provides a nice little pick-me-up (similar to coffee or energy drinks), you’re not alone. You’ll find addicts in both camps"
