To begin with, I do wish they had a version that was a bit more concentrated. I add this to my soda stream sparkling water drinks, and the volume of this I need to make a caffeinated drink sometimes lessens my drinks carbonation. Bubly used to make very concentrated caffeinated drops for the sodastream called "Bubly Bounce," for some terrible reason, they discontinued it. This is a great substitute for that for anyone who loves caffeinated sparkling water like me. I've replaced my morning coffee with caffeinated sparkling water for a couple years now, and I've felt so much better. No more kidney pain or stained teeth. It's amazing to have this for a boost of energy. You can add it to anything because it is truly flavorless. I tasted no bitterness. I love the size and design of the jug. It will last a long time and it's so cool and easy to pour. It shows me the company puts its customers happiness above all. Great product! Would love to see a more concentrated version. Wink. Wink.

This is a money saver, pure liquid caffeine add to anything [ I’ve done it ] and save yourself some money instead of buying espresso shots / 5 hour shots, coffee. Your not supposed to drink this straight, your to mix it in to a beverage. If you follow the directions you shouldn’t have any problems but obviously the one review saying it’s nasty clearly shows they didn’t read the directions. The right side of the bottle has indicators of how much caffeine you can dispense, which is better than guessing. As for the “ To Go “ tube it looks like a container for the male reproductive goo, which I would suggest maybe find a different “To Go “ tube or one or make your own an have a plastics company make it. 94 servings is quite a lot, should last a while. The other reason i buy from this company they don’t use any calcium benzoate which is an ingredient used in foods / drinks to keep it “ fresh “ 😆 which when exposed to heat turns into calcium benzene which is a poison. Buy this an save your money , make your own energy drink/ energy shots. Will buy again :)

Easy to use and meets the added energy need especially as an additive for my home made seltzers.

Great product. No taste and good energy boost. This is quickly becoming a staple and a much more affordable thing than buying energy drinks. Pair with a DrinkMate soda machine (or whatever brand you like) and some cranberry juice and you're in business!

familiy seems to like this. i also add to my lemonade drinks at my vending business. gotta mix it good or it will be very sharp taste. peeps seeem to like it.

A great way to monitor your caffeine intake if you're looking to reduce it, or get caffeine without all the sugar and calories that come with soda.

This stuff is so disgusting. Nothing could cover the bitter taste. It’s straight up chemical. If you’re able to get it down it gets you a caffeine buzz. Make sure not to go overboard.

This is what it says - liquid caffeine with NO flavor. You can literally add it to anything to make it caffeinated and you will no know it's in there taste-wise. It also has a graduated reservoir on the top where you squeeze the bottle and it will fill up to 10-15 mL, for example, so you know exactly how much caffeine you're getting. If you don't like/can't have coffee/tea and energy drinks are not for you, then I think this product is hard to beat.
