Customer Testimonials

We love our customers! Here are some kind words from a few of them!

*Just placed my second order. I had been taking expensive energizer supplements with mixed results. I decided to try your product and you made a me into a repeat customer. It has already got me through a 60 hour workweek. I've given it to a couple of co-workers and they like it also. Carry it in a energy shot bottle. On workdays 1 teaspoon with my coffee in the morning and depending on the day 1 to 1 1/2 teaspoons in water during break times. Keeps me focused and energized.

*This will be my fourth order of the 32oz regular. I love this stuff, I also love how they have stuck extras in my order as well. It's always a nice surprise to get more that what you expected! I am more than satisfied with this company and if you are on the fence about ordering go ahead and do it, you won't be disappointed. It's far far cheaper to make your own energy ________ than to buy it. I don't care what specials or promos the drink companies offer, you simply can not beat this. Everything comes very well packaged, very protected, and it's like Christmas every time I get my order in!

*Got this stuff back when it was 5150. Helped through my first year of a job with crazy hours (both time and shift length). Mixed it with OJ and it did the job just right! Make sure you dilute it but I say that not so much because of the slight bitter taste but rather the caffeine needs plenty of water to go through your bloodstream effectively. The only energy drink that could touch it was Cocaine(the actual energy drink, not the drug).

*I use your liquid caffeine in my hair regrowth formula. Stronger than you can get in consumer preparations. Advertise this and it will definitely boost sales!
Virginia
*2 tablespoons in my 28 oz water bottles, and my 50 mile bike rides zip on by. LOVE THIS STUFF!!

*Hello, First off, I love your product. I have been trying to find some kind of energy supplement that I could use for a while, and yours is the first that worked --though I am confused as to why taking 1 teaspoon of your product worked, and yet drinking a Mega Monster and an Extra Strength Monster at the same time did absolutely nothing, but I digress--. The main thing I was wondering is why you chose to change the name from "5150 Juice" to "Liquid Caffeine." Sure, it's more descriptive, but"5150 Juice" is more catchy and memorable. I still find myself telling people what I just took was "5150 Juice" and then correcting myself to "Liquid Caffeine." Your Satisfied Customer, Fen

*I still drink my monsters, just because i like the taste. but, if I want a kick of real energy I turn to my liquid caffeine now. A guy at drill was drowsy and asked me for some. I gave him about a cap full and he stayed frosty the rest of the day. Wanted to know where to get it. Thanks Liquid Caffeine!
Trey
*I have used Liquid Caffeine for a couple years now. Since I started I have drank very little soda and rarely drink the overly sugary "energy drinks". I now make my own drink every morning. I highly recommend Liquid Caffeine!

*My favorite drink is Rooibos. It is naturally caffiene free which has kept me nursing a hefty engergy drink addiction that runs two bucks a can. There is however a lot to be said for unnatural Rooibos, teeming with caffiene molecules for pennies on the cup. Thank you Grant for making it possible and thank you for your prompt and courteous customer service. PS - The free samples are going to be stocking stuffers this year!

*I have ordered 3 32oz bottles and I have to say Grant is a stud.. Super prompt shipping and feedback. Every time I get an email it is very personal and asking for sincere feedback from me!!! You can tell he is building his company with the most important thing first ..the customer!!! all that crap aside the product ROCKS!!!! use it everyday. I add it to Mio and green tea. tastes great and works awesome!!! I also noticed its a very "clean" energy, hard to explain but it feels refined. No gitters No crash. I highly recommend it.

*Just like they said "We ship everything USPS 2-3 day Priorty Mail" got it real quick thanks gg
Bob, nascar
*The liquid caffeine arrived very fast, as advertised, and when tested, it worked immediately. I could feel it for about four hours, there was no crash, and it kept me awake for the rest of the day. Highly recommended and I plan on advertising it to all of my friends now. Compared to other energy supplements, liquid caffeine is very cheap, and works way better than expected.
Chauncey
*The package arrived! Quicker than I thought it would. I must say thanks again. The small packets are amazing. Def going to have one on me at all time. For my first test I just added it to a 20oz bottle of water. I was expecting some kind of taste, but there was nothing at all. Tasted just like plain water. That really blew my mind. This should be sold everywhere, I mean you can make water into an energy drink. Who wouldn't love that? Everyone in the office loves it. I have been handing them out to people, so far all is great! I've tried them in pretty much everything, water, non caffeinated sodas, pretty much whatever I'm drinking! I could have never thought how quick it would work. Way faster than an energy drink!

*Definitely the best product ever made! I took a challenge to lose some weight earlier this year and I chose to cut out soda completely. Without Liquid Caffeine I don't think I would have been functional. Who wants to pay five or six bucks a day for energy drinks and coffee when you can get it for pennies in your gatorade? This stuff is awesome. I've lost 30 lbs this year and have kept it off with a healthy diet. I've let soda creep back in a little, but not nearly as much now that I've got my Liquid Caffeine to take care of my energy needs! Thanks so much for an awesome product!!!
Anthony
*This stuff got me through law school. Have found nothing better. I highly recommend it.
Omar Serrato
*There isn't a better deal out there if you need/want caffeine. Drop 150mgs of this in your favorite citrus drink, and you will have an instant energy drink. The citrus flavor will cut the bitterness of the caffeine; you won't even notice it's in there until you feel your blood rushing. Highly recommend this to hardcore caffeine drinkers. Your bank account will thank you.
Craig
*Works like a charm everytime i need to study till freaking 3 am. Love it to death.
Traverse
