No complaints, just clicky tappy and the wake up juice shows up a few days later. You can mix it into literally anything. This has helped my wife and I to kick our expensive soda habit. You can mix it into anything and won't even notice it until you suddenly feel awake like you just drank a soda or some coffee.

Fantastic product! I've been using liquid caffeine as a replacement for energy drinks for years. Shipping is always fast and I've never had a problem with my order. The caffeine itself is super easy to add to anything and has a slight bitterness that's easy barely noticeable. I save about $60 a month by not buying branded energy drinks.

I’ve been buying Liquid Caffeine for awhile now. I like the product. The prices are reasonable and the customer service is excellent. Helped me break my soda habit…drink less of it and just use caffeine in other drinks when I need it. PERFECT.
