Reviews


"CILTEP has been by far the most impressive nootropic I’ve ever tried, period."

"If you’ve never tried nootropics before, or have, and noticed meager results, then CILTEP might be worth a try. Unlike most racetams, the effects are rapid and extremely noticeable."

- Chad Barnsdale



"The perfect tool to boost performance and enhance focus for students"

"I was skeptical, as many would be; but after taking the stacks once, then twice, then a third time it was clear that the hype surrounding Natural Stacks is real."

- Zack Huhn, Founder



"Artichoke extract and forskolin has an incredible cognitive effect"

"I've actually found it more effective than modafinil. This a stack that was developed by Abelard Lindsay"

- Tim Ferriss, Entrepreneur, Author and Investor



"I don't want to jump the gun, but honestly it worked instantaneously."

"Not sure if it’s supposed to affect the system as fast as it did, but I had clear focus all morning. It’s been a very productive day, full of reading, writing, and planning for new projects. "

- Alex West, Filmmaker

Mattias Ribbing, World Memory Champion

"This is another very interesting area. Smart drugs and so on is something that I’m starting to learn more about, what works and what doesn’t… My wife set up a blind study for me because I got my hand on some CILTEP… We did a blind test… Out of these 20 trials that I did in these 10 days, my four fastest ones were all on CILTEP. I did 8 failed trials, only 2 of them were on CILTEP."

 


Timothy Ferriss, Author/Entrepreneur

"CILTEP is great stuff. I originally connected with Abelard. I ended up mentioning the CILTEP stack in Wired magazine. This was well before he was producing it with Natural Stacks… I’m a huge fan of this stack. What I find personally, and again, so much of this is dependent on your individual biochemical signature. I love CILTEP, if I use it, I just need to ensure that I can budget for 10-12 hours of sleep that night… For writing it is fantastic."

 


Nick Ehrlich of Sweat Performance

"When I started using this stack, the SmartCaffeine, the CILTEP and the BioCreatine, I found that I take it right out of bed, first thing in the morning, and I have a really nice, focused, kind of laser-guided energy level that carries me thru-ought the day. I don't feel the need to go back, get another cup of coffee, grab a rockstar or anything like that. I'm really focused like this."

 


Adrian West, Filmmaker

"CILTEP. I’ve tried this stuff a few months ago and extreme cognitive benefits. When I first tried it, it was brand new and I felt like it took an effect on my brain in minutes… When I’m at a desk job, like I am here at my studio, I’m good all day. I’ll take it first thing in the morning on an empty stomach. I’m concentrating all day long and am crushing it, getting a lot of work done."

 


Brittney Leeb, Nutritional Coach

"Smart Caffeine helps reduce the effects of muscle fatigue. And gives me that extra boost of energy that I need sometimes. And I also feel like it has increases the efficiency at which my body uses glycogen. Because I can work out longer with or without the product. CILTEP keeps me sharp and focused in all that I do… And since I’ve added BioCreatine I’ve noticed serious gains and more mental focus."

 


Chris Hughes, Entrepreneur

"I’ve been pairing CILTEP up with the SmartCaffeine from The Natural Stacks guys as you can see here. What I’ve been doing is I’ve been surfing for about an hour or two hours right after taking it. and then coming back to get right into my work routine. I’m an internet entrepreneur so this has really helped with increasing my focus and getting things done which are on my to do list."

 


Jerry Daniels, Software Engineer

"I started out today by taking CILTEP. It’s a nootropic, it helps with cognitive enhancement. I’m a 65 year old software developer so I have to have my whits about me and I have to have a good memory and CILTEP really helps me with that. Also, the great thing with CILTEP is that it goes great with caffeine.So if you’re a coffee drinker or if you’d like some kind of caffeine that if very smooth, SmartCaffeine is something they produce that I recommend."



Jacob, Student

"I just want to tell you that this stack really helped me for my exam. It literally saved my life. Firstly, SmartCaffeine. I took about one pill in the morning during exam time… it got me focused.
CILTEP - This product is amazing. When I say amazing, I mean AMAZING.
I took this one alone and still got the effect of clarity and memory."




Ben Morris, Director of Technology

"I wanted to do a quick video of a fantastic product from the guys at natural Stacks. All natural cognitive enhancer… It basically dials you in, similar to caffeine, but a little bit longer lasting. It’s working on your PDE4 inhibition in your brain… but technical stuff aside, 3 capsules a day on an empty stomach right when you wake up… Great product from the guys at Natural Stacks. Highly recommended."





Anthony, Medical Student

"I’m a big fan of Natural Stacks. And this is mainly because they’ve got this really honest approach. It’s quite simple really, it’s to sell products that actually work. And with really transparent ingredients so you can look up what’s in them. And you know that the dose is the effective dosage that is mentioned in the scientific studies. And although this sounds like an obvious, simple thing. This is actually really rare in the supplement industry."
