Smart Caffeine | L-Theanine (Focus), Caffeine (Energy), Iron (Reduce Tiredness) + Magnesium (Anti-Stress) | 100% Natural | 60 Capsules | One Month Supply by Nutribiotical

I took two pills today and I worked for 5 hours non-stop, it was astounding. I'm a pretty productive person but this is on a whole another level. I was also more fearless, weirdly didn't feel stress/anxious at all. I was just a very good mood, optimistic and surging with a huge amount of energy which lasts for 9 hours!

Very very good for what they are. I was looking for something combining Theanine and Caffeine. They caffeine dose is quite high (2 espressos) without the trembling but one day I ate two and had two coffees and I was superhyperactive (in a bad way though)

At first, I was thinking about buying only L-theanine capsules. But CAFFPRO got my attention because of the dosage of L-theanine (300mg), and the plus side of having caffeine. I found that 1 capsule before lunch, between 10-11:30, keeps me working all day long.

I don't rate 0 because it's not an option.silly me not reading the reviews properly before buying . now I understand why most buyers got some sort of discount for their "honest" reviews.I usually take l-theanine itself with a red bull and feel amazing.this item just makes me sleepy and depressed. Waste of money.

Helps me stay awake in some of my lectures, good if you struggle to stay awake during activities like meetings and seminars.

I have tried many caffeine related products in the past. I am pleased to say this is the best so far.

Didn't feel any effect; have been taking these for 3 weeks now? I don't understand whether or not its just me or all the other 5Star reviews here are sponsored?

very good product, fast delivery, I recommend this seller product as very good
