I've ordered from Kaffn8 many times
I've ordered from Kaffn8 many times, and my order always arrives within 3-4 days. I use a little in my morning juice, which helps me stay awake since I don't drink tea or coffee.
I love Kaffn8
I love Kaffn8! As a mom who works full time and is also a full-time student, I get tired around 3pm, and feel drained by 8pm. So I use a little Kaffn8 in most of my drinks throughout the day, including softdrinks, sparkling water, tea, lemonade, and protein shakes to avoid the evening crash. It gives me the pick-me-up I need to keep going. I am able to hit the gym at 530am, work all day, take care of the house and family in the evening, then do school work well into the night.

This liquid caffeine is great
This liquid caffeine is great! I use very little and all I notice is I have more energy to get through my day and get more done. No jitters or shakiness at all! Love it!
Great option for safe, effective energy
I much prefer to get my caffeine without having to resort to soda or flavored drinks that may not be safe. I add a bit to my water or tea, giving me that little boost of energy without going overboard.
Great Measured Caffeine Product

They are a great company to deal with and have a great product. Definitely a fan!
Love this product
Love this product. No flavor and keeps you going!
Great product!
Great product, easy instructions. The taste is a bit bitter - in fact it tastes a bit like 5 hour energy. This isn't a problem per se, but just understand there is a bit of a taste to the product. You need to mix it with quite a bit of liquid to get the flavor to dissipate. Very clean feeling, no jitters!
Great product
Great product! We use it in our drink business.. I love it (great pick-me-up, with no jitters) and customers have returned for more! Packed well and fast shipping. (I just received my 2nd shipment.
Quick delivery.
Quick delivery. A great product that gives me control of my caffeine intake.
Website layout is intuitive
Website layout is intuitive, price comparing between options is easy (so many companies try to obfuscate this), and the service has been great as far as shipping schedules, packaging, communication.
Exactly what I was looking for
Loved everything about it. Fast shipping, didn’t arrive damaged, easy to use container, can’t taste it at all & works perfectly for what I needed. Plus, a handwritten thank you note. Very impressed.
