Good product and pricing adds value!

Was drawn to this product to have a more reliable source of caffeine intake combining L-Theanine with caffeine. Packaging was secure: arrived in a bubble-wrap envelope. My only suggestion is that the L-Theanine might be more optimally dosed in a 2:1 ratio to allow more of the caffeine stimulant effects to be felt especially considering a tolerance to caffeine is quickly built in most people over time. Other than that I liked the quality, presentation, delivery time (less than a week within EU) and effortless transaction with FocusSupplements. I can definitely recommend this product from you to others!

Great alternative of coffe

Free shipping to Slovenia! Yaaay <3 If you are looking for alternative and upgrade of your morning coffee - this is it! The product is of great quality and the price is fair. I love the quality and design of the bottle. Delivery was almost on time (one day late), but the outer box packaging came a bit damaged, because its send in an air bubble envelope, but technically it doesn't matter for me.
