This whopper is a 4.26 fl oz energy shot that lives up to it’s label. Speaking of the label, there is a see-thru strip on the side of the label so you can measure how much you consume (this is a double shot so this feature came in handy!). I thought this was very clever on behalf of their packaging designer. Although I was not SUPER impressed by the flavoring, this shot was not bad. I could not find a flavor on the label besides “original” but this is a fruit/berry mix. This shot gave me sustained energy throughout the whole day. We bought these at $3.99 a bottle, which is awesome because this is 2 shots in one and should be consumed as such.  Great effort from Spike. How can we get our hands on some of their carbonated stuff?! spikeshooter.com [4/5 STARS]
