Energy Drink, Ultra Violet, Can 16 OZ Zero calories + zero sugar. Caffeine from all sources. 70 mg per 8 fl oz serving (140 mg per can). Welcome to the 70's. A hazy purple funk all dressed up in a kaleidoscope of bell bottoms, bandanas, and tie-dye. A time when psychedelic glam and heavy metal rock blasted from mega speakers at fairgrounds, stadiums and garages. Can you dig it?
