A fruit energy drink, high in caffeine. Add pro-plus and a bit of vodka, you'll be bouncing off walls in no time.
Hey did you just see Jimmy!? He downed a relentless cocktail of pro-plus and caffeine, then he jumped out of the window thinking he could fly!

An energy drink, mostly drunk by BMX ers in Farborough. Nornally gone on halves, two people buying a four pack paying half each, and a great drink to replace Red Bull

Guy2"Yeah, wanna go halves on a four pack of Relentless?"
