LOVE ❤️ Kaffn8 - Highly Recommend - Long time customer

I wanted to give an updated review as of 4/2025. I have been purchasing Kaffn8 now since 9/2020. Five years of ordering and I'm still satisfied. I always buy in large quantities, because this is both mine and my boyfriends go to energy pick me up. 🥰I started my journey with Kaffn8 after bariatric sleeve surgery and getting kidney stones from drinking Monsters 👹. I searched for a long time, tried other caffeine supplements but felt miserable, irritable, jittery or head fog/ headaches or would resort back to Monsters before I found Kaffn8. I frequently put this is my soda stream drinks or protein drinks, and will occasionally when in a rush drink it straight. (*Note it is bitter tasting to me straight, I'll chase it with water.) Every morning, this is brought to me in a small cup with some type of juice, usually cranberry juice as I wake up... I literally can not function without my shot of caffeine. My boyfriend also switched from 5hr energy drinks to Kaffn8, he always drinks it straight. Because we both drink this daily, I have to buy in bulk because neither of us drink coffee or can go without caffeine. 🤣 I recommend this to people I work with daily and to anyone reading this long review. 🤠My only suggestions for Kaffn8 is for them to continue selling at a reasonable cost and for them to consider making caffeine edibles that are easy to carry in a car or purse for days you may need a little extra boost, with the clean ingredients you have in Kaffn8. (Like gummies, chocolates, mints, or gum) I've seen other brands have caffeine edibles, but they are filled with added stuff I don't want to consume. Thank You Kaffn8, long time customer here! Diane Young 🥰
