F5 was a project to create a RedBull sub-brand for soluble
energy tablets. The F5 refers to the F5 key on a keyboard used to refresh a page. The product was marketed toward students and gamers, who needed an energy boost. This included branding for the sub-brand itself, the packaging for the tablets, and a huge promotional CSGO tournament for the launch of the product and RedBull's own CSGO team, with supporting merchandise and social media.
