We’re all zipping around the place like coke-crazed rappers, courtesy of our new client, Go Fast energy shots.

A tiny bottle containing a tasty, but potent, blend of ginseng, ginkgo biloba, guarana, caffeine and vitamins B2, 3, 5, 6 and 12. As well as a 100% natural fruit sugar known as Fruit-Up.  And only 5 calories a shot.

Commercial over. Basically, it has all the power of a full size energy drink concentrated into an easy-to-drink 50ml shot. Kind of like the difference between a pint of beer and a shot of bourbon – same number of units, but it doesn’t take you 20 minutes to knock it back.

The question is, does it work?  Indubitably.  And quick as a flash.

But don’t take our word for it, try one, next time you’re suffering from that post-lunch slump in the graveyard slot between 3 and 4pm. It’ll pick you up faster than Russell Brand
