Energy shot

5-Hour Energy, berry flavour. "Regular Strength" implies that there is a version of this product with even more caffeine - oh my!

An energy shot is a type of tonic drink with a notably high amount of caffeine sold in small quantities, usually having the same amount of caffeine (or more) as a standard can of energy drink but in a small, liquor shot-sized bottle, around 50 ml ((about 1.5 fluid ounces).

The most popular brand of this type of product is America's beloved 5-Hour Energy, currently even sold in standard metal drink cans, as per the popularity of high-caffeine energy drinks in the States. Lithuania isn't particularly notable for having this type of drink, except for Nutri Energy Power, a 100 ml bottle energy shot with a total caffeine count of 100mg. Sport supplement stores also used to sell some other brands of caffeine shots.
