If you like the effects of energy drinks but not the taste you can now make your own with the help of Umph.

You can drop an umph tablet into your favourite beverage which will immediately transform it into a drink with wings. Each tablet contains 99 milligrams of caffeine and 30 milligrams of Panax Ginseng along with Vitamin B6. So if you need to a 24 hour revisions session or meeting some stupid salesman’s promised delivery date then add a little umph.

Available from TG in packs of 20 individually wrapped tablets, which should be enough for many a frag fest.
