01/ BUILD A BETTER BRAIN
Do you ever experience “brain fog”, where it’s impossible to think clearly?
Do you sometimes have trouble focusing and solving complex problems?
Have a big to-do list or goals you want to hit, but no motivation?
This happens to all of us and as we age these things tend to get worse, but the good news is they don’t have to!
There’s a reason why doctors, firefighters, students, moms and dads around the world are using NEUROFUEL™ to boost their focus, motivation and memory.
NEUROFUEL™ is a 100% natural formula for better brain performance.
Whether you’re looking to learn a new skill, get a promotion at work, or get back to doing more of the things you love… NEUROFUEL™ can help.
Users often report:
Increased motivation and mental endurance†
Improved concentration and alertness†
Improved mood and social ease†
Enhanced ability to study and learn new information†
All it takes is two capsules on an empty stomach before your work or focus session. Thirty minutes later, you’ll feel the fuel go to work.
How It Works
NEUROFUEL™ provides your body the natural ingredients it needs to fuel a process known as It is regarded by many as the key to learning new things and retaining that information.
That’s why we say “FEEL THE FUEL”.
When LTP is enhanced; you’ll be alert, intellectually curious, and feel more creative.
So Powerful That It’s Patented.
NEUROFUEL™ is the original CILTEP formula and is protected by US Patent #US9149457B2.
03/ SUGGESTED USE
Take 1-3 capsules in the morning immediately upon waking on an empty stomach, or as directed by a healthcare practitioner. Do not take more than 3 capsules per day.
Some users find that a moderate dose of caffeine in the morning and/or early afternoon extends and optimizes results (We recommend SMART CAFFEINE®).
CILTEP® can be taken daily, however we advise taking 1-2 days off per week (weekends for example).
U.S.A manufactured in a GMP facility. Natural Stacks proudly uses only the highest quality ingredients.
CILTEP® is protected under U.S. Patent 9,149,547
04/ FREQUENTLY ASKED QUESTIONS
When should I take NEUROFUEL?
We suggest taking NEUROFUEL™ first thing in the morning on days that include demanding cognitive tasks.
Take it on an empty stomach and 20-30 minutes later, you eat breakfast or – our favorite, have some bulletproof coffee for an extra spark.
How does NEUROFUEL work and what will I feel?
NEUROFUEL™ increases focus and potentiates long-term memory but doesn’t rely on neurotransmitter manipulation to elicit this benefit. Because NEUROFUEL™ is not a stimulant and it doesn’t directly impact our neurotransmitters, the “feel” is very subtle.
What you notice most is that time seems to slow, distractions fade away (increased focus), and you have a strong desire to learn/read/work.
The more mentally demanding the task, the more NEUROFUEL™ shines.
Many users prefer to “stack” or combine NEUROFUEL™ with one of our Brain Food products.
The Brain Food line is designed to give individuals the tools needed to optimize whatever neurotransmitter they may need to moderate on any given day or at any given time.
What is NEUROFUEL?
NEUROFUEL™ is a natural nutritional supplement designed for improving and maintaining brain performance. It’s theorized to improve learning and memory in the brain by supporting and optimizing levels of intracellular secondary messengers.
Are there any side effects?
There are no known side effects if used as directed. For that reason, thousands of people have chosen all-natural NEUROFUEL™ as their preferred nootropic stack.
Do I have to cycle NEUROFUEL?
No you do not have to cycle NEUROFUEL™.
Normally people take 2-3 capsules during the work week and then off on the weekends.
What happened to the CILTEP Nootropic Stack?
CILTEP® (sil-tep) is a nootropic stack or smart drug used to improve mental performance.
It was developed in 2012 by world renowned biohacker Abelard Lindsay, patented and then licensed exclusively to Natural Stacks.
In 2020, Natural Stacks changed the name of CILTEP® to NEUROFUEL™.
The same powerful, patented formula remains the same but it’s now available at a new lower price.
Is NEUROFUEL vegan?
Yes. It’s all-natural, vegan, soy-free and paleo.
When is the best time to take NEUROFUEL?
NEUROFUEL™ works best on an empty stomach.
You’ll feel the fuel fast, within 30 minutes of your first dose.
Due to the effects it’s recommended to take NEUROFUEL™ during the daytime or early afternoon.
What is the science behind NEUROFUEL?
The formula works by:
PDE4 Inhibition + Increasing cAMP = Long-Term Potentiation
Developed by Abelard Research, the NEUROFUEL™ Formula is a protected by United States Patent and Trademark Office US9149457B2.
PDE4 is an enzyme that breaks down cAMP molecules, messenger systems that relay signals in the brain.
Inhibition of PDE4 blocks the breakdown of cAMP, and thereby increases levels of cAMP within brain cells.
This has been shown to lead to increased cognition, improved long term memory, increased wakefulness, and neuroprotection. [3,4,5,6,7,8]
There have been several natural PDE4 inhibitors identified in herbal preparations including luteolin, which is present in artichoke extract. It also inhibits PDE 1 through 5 which have both shown beneficial activity with regards to synaptic plasticity. [1,2]
Artichoke Extract is a safe, effective and natural PDE4 Inhibitor. [1,2] NEUROFUEL™ contains 900 mg of the highest quality Artichoke Extract in each serving.
The herb Forskolin (active compound extracted from the root of the Coleus Forskohlii plant) has been shown to naturally increase cAMP levels.
It activates the enzyme adenylyl cyclase which then increases intracellular levels of cAMP. 
Neuro Fuel™ features premium Coleus Forskohlii standardized for 20% Forskolin. There are 4 mg of Forskolin in each serving of CILTEP.
Increasing cAMP and inhibiting its degradation supports Long-Term Potentiation (LTP).
Summary: PDE4 Inhibition + Increasing cAMP → LTP → Supports optimal mental performance
What makes NEUROFUEL better / different than other smart drugs?
NEUROFUEL™ uses a simple, all-natural formula that works by increasing the number of messenger systems inside of your brain cells.
This enables neurons to quickly communicate with each other and retain information. It makes you more engaged and efficient at whatever mental task you might be doing.
NEUROFUEL™ enhances your mental capacity without relying on altering neurotransmitter levels.
It acts inside of the cell to naturally strengthen connections between neurons, promoting improved learning, memory, and cognitive function.
