No way to give enough stars! Seriously, the Kaffn8 product is simply the best way to get caffeine. The autoship set-it-and-forget-it service is fantastic - I will never run out!

I got a brain injury kaffn8 helps symptoms I got a brain injury permanent brain damage, reactive gliosis as a result of this concussion so I suffer with headaches daily, and cognitive issues so I was given Ritalin, but I don't like Ritalin, so I began looking for jolt energy cola for caffeine but jolt is no longer for sale and searched for caffeine and found kaffn8 and I put it in my coca cola and it taste like jolt cola and get the caffeine I need. I no longer need Ritalin thanks to kaffn8,. Please don't stop selling this product. Because of your product kaffn8, it allows for a natural healthier way to deal with post tbi concussion syndrome symptoms instead of Ritalin a narcotic

Love this product! Love this product! It makes it easy to add a little caffeine to my bubbly water without adding sugar or other chemicals. And you cannot taste it! Easy to order and shipment was fast.
