Great flavorProvided extra energy mid day on vacation

My husband enjoys these very much and it's cost effective to buy them this way

The best energy shot made

So, this is a fantastic product.To a slightly lesser degree, also the grape flavor. Thing is, this berry one is so nasty, you can hardly gulp it down.But...that's the genius!You start, it takes 3-4 gulps...And you'll barely get each gulp in...but the taste, is why it works so well.No reassuring fruity sweet nice taste..No, this one hurts going in...which that alone wakes you up..but then the formula goes to work on you, and you become fully aware of the power of the components that keep you awake.THIS ONE WORKS. TRY IT.

my wife loves these.

I don’t drink coffee or take any kind of caffeine supplements on a regular basis because I’m very sensitive to any kind of stimulants. When the product arrived, I saw on the side of the bottle that each bottle is two servings. I drank half a bottle and waited a while, nothing. I drank the other half a bottle and waited a while, nothing. Since I had to drive 600 miles by myself, I couldn’t afford to be drowsy. So I drank another complete bottle by itself, nothing. I ended up driving from rest stop to rest stop to try to avoid drowsy driving. I was successful most of the way, but there were times when I realized I didn’t know what had occurred over the last 5 to 15 seconds? Extremely stupid of me that won’t be repeated. So no, I cannot recommend Tweaker. Funny that they name the product after speed freaks without providing any stimulant effect at all. I wish on this trip that I actually had had some speed!

I've been using these for sometime, and they get the job done as far as giving you an energy boost. However they were poorly packaged by someone who could obviously care less about what they're doing or the customer. The boxes the dozen bottles come in were beaten to a degree where it looks like someone ran over them with a car. They were also stained all over by an unknown liquid (although it was not from the bottles themselves, each being intact). I highly recommend the product, but you're taking your chances on receiving them undamaged.

Found this at my local gas station intrigued by the name I tried it out. Took one shot and ended up doing a DEEP clean of my car that I’ve been meaning to do. Super focused, sustained energy and I’m a caffeine junky so I immediately went online to buy the box. (I also noticed “down there” had more “energy” thanks to the added yohimbine) worth the money very cheap
