Ciltep has been renamed “Neurofuel,” but still has the same ingredients and effectiveness. This supplement is my favorite to take in the morning with my coffee while fasted. I usually take 2-3 capsules and notice sustained mental focus and energy during the work day.

At 48 I noticed a growing difference in my focus and memory. Other supplements were not improving the situation. However within 2 weeks of taking 2 capsules each morning, 30 mins before any food I feel confident that my cognitive performance is better.

Neuro Fuel has subtle effects but when paired with smart caffeine, it makes for productive days and quick thoughts. The way I've described Neuro Fuel before was “my brain feels hungry” and “my head feels larger and my brain feels like it’s growing to fit it”

I'm a 53yr old grandpa and I've been using nootropics for about 6 months. I started using Neuro Fuel 3 months ago after recieving the 10 day free trial. My focus at work and in the gym have improved dramatically. Try it you have only the fogginess to lose.

Neurofuel has help me have better memory and clarity of thought. I take it first thing in the morning on an empty stomach. It also works well with some of the other Natural Stack's products.

This some good ingredients in it. I didn't use it too much, but it seems to give me a calming effect when I stack it with some smart caffeine. I have not really tried it by itself, so I can't really give too much of a full opinion of it. Give it a try to see how to affects you.

Neuro Fuel helped me to stay focused and alert as I was learning the ways of my new position in a new department after 20 yrs as an educational statistician. Neuro Fuel helped me to effectively learn my new position and feel confident. It also helped me to stick to my renewed commitment to better physical and mental health, while juggling a full-time work schedule, part-time job, and full-time mothering through the summer break. Thank you! Thank you! Thank you!

Takes the pills about two and a half weeks. There is a benefit in the way my wife thinks of me. I got a compliment from her that I am smart. .... I find it hard for me to feel the change. Feel it working slowly and I will only feel change in a month

Neuro Fuel is a great way to get the day started and it helps me stay focused on the tasks in front of me. I started taking it and within if a few days, I noticed a big difference in my focus and staying sharp throughout the whole day. I strongly recommend Neuro Fuel as part of your daily routine.

I feel so much mentally aware now. I've been taking Neuro Fuel for about a month, and the results are incredible. I feel more creative, decisive, and able to put words to thoughts so much more effectively. All I can say is, thank you for this wonderful product!

I have been taking Neuro Fuel for over one year and I really notice the difference. I take two caps first thing in the morning on an empty stomach. I only take it on days that I know my work load will be heavy and when I need to have focus as well as quick memory recall. I would recommend it to anyone who wants a boost in memory, mood and productivity.
