Ben was amazing
Ben was amazing, to my experience. There was a mishap, and package was delayed. He remedied the situation quickly, and even provided a discount code! I'll definitely be ordering again thanks to him, keep this one around 😊

They just keep getting better!
I've been a customer for a couple of years now and I continue to be happier and happier with liquid caffeine. Over that time they have started using loyalty points, improved thier packaging, and continue to deliver a top notch product that I have used every day. A+++

The product is as advertised
The product is as advertised. I just learned that inhaling caffeine fumes is also important to be able to get a "buzz" on.
I would recommend an _option_ for a concentrated dosage at a slightly discounted price. It takes me four pumps to feel something (as opposed to the recommended one or two...)

Better than plain coffee
I have narcolepsy and this keeps me away without the use of amphetamines

Timely delivery
Timely delivery. Great prices. Helpful info on the website. Couldn’t be happier. Plus it’s WAY less expensive than coffee or energy drinks. I hope you stay in business a long time, or at least until I die and won’t need caffeine any more.

Liquid Caffeine - great product, great price!
I've bought from Liquid Caffeine before. Their caffeine products are unique, they are very nice quality, the caffeine is just as advertised. Communication about your purchase status is prompt, and shipping was fast. The prices are quite reasonable and I've always had a great experience with Liquid Caffeine.

Fantastic!!
I’ve been enjoying using the liquid caffeine product. It’s easy to dispense from the pump bottles and mixes in well with my electrolytes in the morning. Customer service is GREAT.

Good products
I've been purchasing from Liquid Caffeine for several years, and the product is always consistent. Their website is glitchy, but it gets the job done.

Excellent caffeine source instead drinking energy drinks or energy powders or pills that would make you sick.
I like how it is versatile to blend in with any liquid. I even tried mix it with straight water and it didn't change how the water taste.

Longtime customer
I need caffeine to counteract medication side effects. I don't like coffee. LC, which I've been utilizing for more than a decade, is the perfect solution
