There are not many pre-made nootropic stacks like CILTEP that has its own place in the history of industry. In CILTEP review we examine:

  • tricks & tips of using ciltep

  • Is it worth the hype?

  • Why is CILTEP known for adaptable focus and memory improvement? 

In the era of popular mind-enhancers, which capacity is to provide us much better focus and increase in cognitive abilities, CILTEP stack is exactly what every real nootropic fan wishes to have a look at eventually.

Students, scientists, doctors, business executives, filmmakers, firemans, and lots of others reported the efficient usage from enhancing awareness and endurance, to having additional sharp focus and memory increase. 

Produced by Natural stacks, the world’s first open-source supplement company, the objective of CILTEP stack is to assist individuals achieve far better results with all-natural ingredients.

CILTEP history

CILTEP is the first modern nootropic supplement created and improved within the Longecity forum community in 2011. Its creator is the world-famous biohaker Abelard Lindsay. Abelard made CILTEP for his own use as ‘DIY stack’ before being made by Natural stacks as an all-in-one solution.

Numerous reports are blogged about CILTEP, as a result of the truth that it is one of the most effective 100% natural nootropics.

It utilizes just a few all-natural ingredients meticulously crafted to enhance the brain and its capability to develop long-lasting memories through the biological mechanism called long-term potentiation.

The concept behind CILTEP is still highly theoretical as well as anecdotal. It is basically an oversimplification of complex cellular mechanism into elementary mathematics. Yet the hype is being born because the product is working and also users from worldwide resemble it. The reactions blossoms all over the internet.

Even some stars are CILTEP big promoters. Like Dave Asprey of Bulletproof along with the author of the preferred book “4 Hour Job Week”, Tim Ferriss. You should know that any popularity of a nootropic product or even great fame depends on the marketing and who is promoting it. It’s equally or more important than just being good.

So, what is CILTEP?

"CILTEP has earned a place alongside world-class smart drugs like piracetam, gingko, and choline. It works synergistically with them to you do - and be - more."

What CILTEP stands for?

While it’s impossible to chemically cause memories, given that discovering of new things as well as learning is what makes us smarter, there is a biological system behind the brain’s ability to form and store the new knowledge and behavior, memories that can last up to a lifetime. It is called long-term potentiation (LTP).

CILTEP is a phrase for “chemically-induced long-term potentiation”. We can add words ‘enhanced’ for ‘E’ in the CILTEP stack due to the fact that enhancing is the only method this product can contribute to this natural phenomenon which takes place by itself.

While theory about LTP is much older and dates back to the late 19th century, CILTEP concept stemmed from an intriguing study in 2003. about Forskolin-induced long-term potentiation. This research study pointed towards of the approaches of supplementing to enhance this cellular effect.

Chemically induced long-term potentiation (cLTP) could potentially work by
directly stimulating the biochemical machinery that underlies synaptic plasticity, bypassing the need for synaptic activation. Previous reports suggested that agents that raise cAMp concentration might have this capability. 

CILTEP is created to aid your mind cells interact better with each other and assist with your short-term and also long-lasting memory. Therefore this nootropic blend can be beneficial to anybody from young student to elderly person who just attempting to get their brain back. 

CILTEP stops the brain fog all of us have at those moments when it’s impossible to remain focused. And allow me to inform you, those five major active ingredients brings very sharp focus!

The boosting in the activity of other essential neurotransmitters such as acetylcholine, dopamine, and epinephrine will certainly benefit the rising in cognitive capacities along with a general speed rate.

Due to that activities and because it improves the level of sensitivity to numerous hormones and natural chemicals, people also utilize CILTEP to naturally enhance athletic performance.

CILTEP ingredients

Artichoke extract contains Luteolin, a natural inhibitor of a PDE4 enzyme. While excess levels of PDE4 breaks down cAMP molecules, crucial for neural signaling in the brain, studies have found that Luteolin stabilizes and increases cAMP. It promotes neurogenesis, and reduce inflammation in neurons. Boost mental performance, improve long term memory and increase wakefulness.

Forskolin is derived from the plant Coleus forskohlii which has been widely used in traditional Ayurvedic medicine. Forskolin activates the enzyme adenylate cyclase which increases cAMP (Cyclic Adenosine Monophosphate) levels in brain cells. Combined with Luteolin from Artichoke Extract, forskolin is theorized to synergistically increase the duration of cAMP in neurons.

Acetyl-L-Carnitine, or ALCAR, is an acetylated form of the amino acid L-Carnitine that is the precursor for acetylcholine messenger. ALCAR helps in brain energy metabolism and mitochondrial protection and can boost physical and mental energy. The addition of ALCAR to the CILTEP formula helps combat feelings of brain fog and fatigue. As an antioxidant, it also provides neuroprotective qualities.

L-Phenylalanine is an essential amino acid that can be found in protein-rich both plant and animal foods. Phenylalanine can be transformed into the amino acid tyrosine, which is then used to produce essential neurotransmitters. Epinephrine, norepinephrine, and dopamine. These molecules are involved in your body’s normal functioning, including your mood and reaction to stress.

Vitamin B6 is one of 8 B-vitamins and an important enzymatic cofactor in normal metabolic and psychological function. It is required for the synthesis of dopamine, epinephrine, GABA, melatonin, norepinephrine, and serotonin. CILTEP features the metabolically active form of Vitamin B6 for optimal bioavailability (Pyridoxal-5-Phosphate).

cILTEP formula

  • 5mg Vitamin B6 – Cofactor for neurotransmitter synthesis.
  • 750mg ALCAR – Acetylcholine support.
  • 500mg Phenylalanine – Building block of noradrenaline and dopamine.
  • 4mg Forskolin (standardized for 20%) – Enhances CAMP production.
  • 900mg Artichoke – Acts as PDE inhibitor.

Memory development and synaptic strength are strongly interconnected. By chemically enhancing and inducing LTP, Natural Stacks assert that their ingredients can stimulate:

  • memory

  • concentration

  • cognition

LTP is the mechanism whereby the brain generates proteins required for nerve cell development and where synaptic connections get stronger in action to electrical stimulation in the brain. It is likewise an important part of synaptic plasticity. It takes place in glutamatergic nerve cells, after adequate excitement in between the very same number of neurons, during a specific period of time.

The basic property of LTP is that the neuron keeps forming stronger connections through NMDA as well as AMPA receptors. NMDA receptors play an essential duty in memory as well as learning.

LTP begins when an electrical signal referred to as an action potential reaches the axon terminal of an excitatory synapse. This causes the neurotransmitter glutamate to be released into the synaptic cleft. Basically, AMPA channels open in response to glutamate (or other excitatory neurotransmitters) and allow sodium to pass into the cell.

Once enough of them open this will provide enough Na to depolarize the membrane of the neuron allowing for the Magnesium that is stuck, blocking the NMDA channel in its resting state, to leave. The NMDA receptor then depolarizes via sodium and calcium ions that enter the cell. Once calcium (specifically) begins entering the neuron, a series of enzymatic processes are triggered. These calcium ions cause the phosphorylation of AMPA receptors via CAMKII, increasing their capability to depolarize the cell during subsequent stimulation. The results are the enhancement of existing AMPA receptor activity and placement of new AMPA receptors into the postsynaptic membrane by triggering other intracellular mechanisms. That allows the future excitatory stimuli to generate a stronger postsynaptic response in the potentiated neuron. This aspect of LTP is a singular, albeit important, component of learning. 

CILTEP mechanism of action

Cognition and memory enhancing properties of this supplement is the result of inhibiting the breakdown and elevating of cyclic AMP molecule (cAMP). The cAMP is involved in long-term potentiation, and raising the cAMP levels can chemically cause LTP.

Theory behind CILTEP is that artichoke extract is a good source of luteolin. Luteolin is a PDE4 inhibitor and can thus raise cAMP levels. Forskolin increases cAMP levels by inhibiting its demise. And you can combine the two and create a significant elevation in cAMP levels and subsequent facilitation of LTP mediated by CREB, like you would get from a potent PDE4 inhibitor (rolipram).

Let’s look at how CILTEP ingredients are able to chemically induce long-term potentiation in this schematic preview.

long-term potentiation CILTEP ingredients graphic

PDE 4 and other inhibition

PDE4 is an enzyme that breaks down cAMP particles, carrier systems that relay signals in the brain. Restraint of PDE4 obstructs the breakdown of cAMP as well as therefore raises degrees of cAMP within brain cells. This has been revealed to bring about increased cognition, enhanced long-lasting memory, enhanced wakefulness, and also neuroprotection.

cAMP Increase

The herb Forskolin (active substance extracted from the root of the Coleus Forskohlii plant) has actually been revealed to naturally boost cAMP levels. It’s essentially the only well-known herb able to do that. It turns on the enzyme adenylyl cyclase which then raises intracellular levels of cAMP. CILTEP features premium Coleus Forskohlii standardized for 20% Forskolin. There is 4 mg of Forskolin in each serving of CILTEP.

Dopamine Metabolism Support

A method to a lot more enhance the influences of cAMP from this stack is by including a substance to naturally increase dopamine levels. Increased dopamine response is to be anticipated as a result of the synergy result with various other active components. That increases the additional cAMP levels if the proper D1 dopamine receptor is activated.

Other compounds that are more likely to aid D1 act indirectly, using the NMDA receptor. Synthetic families of racetams or ampakines (Sunifiram) have the ability to do that. As well as natural supplements that support dopamine production, such as L-tyrosine or Phenylalanine.

One of The Best Nootropics Available

Working in an investment risk management role, I wanted a nootropic to help keep me on top of my game. Of the ones I've tried, Ciltep is by far the best and is now an integral part of my morning routine. I take three pills with a cup of green tea every weekday morning. My job requires me to make critical decisions in a matter of seconds, and there's a noticeable difference in my job performance on days where I've taken Ciltep versus days I haven't. Ciltep gives me a heightened sense of alertness without making me jittery like other nootropics. I find that I'm able to think far more clearly (especially early in the morning where I'd normally be a little foggy) and am a better problem-solver and decision-maker because of it.

Difference in memory, drive, and critical thinking

This stuff is great. Will definitely buy more. I can tell I difference in memory, drive, and critical thinking. Mostly memory. Puts me in a generally better mood than normal and not as groggy in the mornings.

A big plus for me

You can buy the individual parts cheaper; Also, tailor your stack a little bit better that way, over time.
I like CILTeP quite a bit; Have had good results with it, particularly adding piracetam and choline to the stack. Much improved clarity and great focus, and ability to shift focus and return without losing ideas or track of work; A big plus for me.

CILTEP side effects

Adverse effects are minimal and pretty rare, given that raising the cAMP levels in small amounts is not something which is considered a big deal. Furthermore, PDA4 inhibitors are well known to cause nausea or vomiting if taken in high amounts.

You may wish to progressively increase the dosage of CILTEP to three capsules in maximum.

If you are making your home version of CILTEP with bulk powders, you may want to start with the standard doses or bellow of each ingredient to feel the effects.

Many experienced neurohackers claim its a placebo, and yet quite a few of them swear by CILTEP. Some users have actually reported fatigue after taking the stack for some time. With the later addition of dopamine supporting supplements and also a forskolin dosage of less than 5 mg, this has been much less of an problem.

Some users have reported lessened working memory while taking the stack, particularly when taking higher doses of forskolin or when taking the stack with Quercetin, which is not recommended.

CILTEP vs. Tobacco

Some reviewers and also anecdotal expressions advise to not smoke tobacco when you are using CILTEP, since pure nicotine might straight prevent the procedure that CILTEP is encouraging.

Long-term potentiation (LTP) has a memory-like consolidation period during which it becomes progressively stabilized. However, it is unknown how the consolidation is achieved. The present study demonstrates that nicotine reverses stabilized LTP in the hippocampal CA1 region, providing the first evidence that consolidated LTP can be reversed. 

CILTEP and stimulants

Powerful stimulants spoil the benefits that CILTEP has, yet also restrict mental fatigue as the effects of CILTEP wear out. I may be too stimulated to work and also think conveniently even if I consume too much coffee with it. Try to watch out when you’re adding more dopamine precursors into the stack. 

Standard Disclaimer: The evidence for this stack is largely theoretical and anecdotal. Proceed at your own risk, preferably after reading the whole Longecity thread. Please check with your doctor before starting a new supplement regime, especially if you have any health conditions.

My experience with CILTEP

I discovered from the start that CILTEP is a really risk-free supplement. It does not create a habit, nor did I feel any negative effects. It has one of the most simple formula I have used so far with just a couple of natural ingredients and focused systemic influence on the body. When I am using it occasionally I would say it has the best effect.


As I always cycle nootropics, I waited a couple of days prior to I add it to my daily meals. Beginning with the lowest dosage of one capsule in the morning, then two capsules after lunch, I started to notice the effects from the very first day. I would say that it’s stimulative enough to not suggest the maximum dosage from the start. Especially if you are not experienced with ingredients. Also if you take it on an empty stomach the effects would be more noticeable.

CILTEP focus; my experience

The other days I would take three capsules in the morning with the light meal and then finished it with the coffee which is optional. You might really fly away to your work like I was feeling the first days. It’s enjoyable and engaging with all that focus when you’ve got a lot of work to do. I’ve even got the popular effect of tunnel vision with a maximum dose of CILTEP. I was well prepared to be busy that day doing some projects and then remain in the moving doing some social meetings after the work’s end. 

After a whole week of energy supply, I was starting to feel drained and somewhat in the ‘not me’ mode. My energy levels started to be inconsistent with everyday use. So I was dosing it more carefully and take a break a few days the next week. I have a good time on CILTEP when interacting socially and will utilizing it for sport and learning activities. Just not for everyday use.

With nootropics, the most important thing is what you need them for. It seems that I did not need much mental stimulation, except for a few days a week. As always with nootropics, the good workout is what enhances them.

I would not state CILTEP is my ultimate stack but I was really hooked into the formulation as well as to some other great nootropic blends from Natural Stacks. I would certainly recommend that you check out the entire range of products they offer.

I’ve compared CILTEP to many other nootropics I’ve checked, and some similar blends I am using and liking. 

CILTEP vs. nooCube

Bottle of supplement with capsules outside of itIn my opinion, these all-natural stacks will rank differently among different people. As a matter of fact, the most potent nootropics, if they are natural, will work for 6 out of 10 people. But when they are working then it’s a big time!

The nootropic stacks is a set of different traits coming together to have a more powerful effect. If you don’t respond to some stand-alone ingredient that will be less clear in stacks, but the result will be overall weaker for some individuals.

For my biochemistry and goals, NooCube tends to work on my mood just perfectly. It mellows me and gives a friendly vibe. It gives me empathy and social intelligence. That’s something I didn’t recognize in other nootropic blends I’ve used. 

With CILTEP, I was getting the feeling of greater focus as well as the overall stimulation in the serving size. I was also getting the least side effects over time (headache, digestive, intestinal). 

Does that make the CILTEP a winner? Not really. They’re both great and different people will have their favorite. 

It should be said that although both stacks are better to feel over time, it is wise to periodically stop from all nootropics. That way you will not feel the tolerance build up nor the feeling that stack is working just the opposite then it should.


THRIIV by Nootripure Laboratories is a more complicated supplement than CILTEP.

On the surface, both stacks supply the body with similar mental energy and focus. But THRIIV got the combination of natural and synthetic ingredients, as well as slow natural release in the effects of ingredients. Adding the CBD content, as well as the best nootropic extracts, THRIIV is more like for the whole body wellness as well as a more relaxing supplement. 

Nootripure’s research is directed towards targeted biological delivery systems, which enable our bodies to absorb the right nutrients at the right time, thus reducing the side effects of medicinal compounds. While other supplements may wear off over time, THRIIV has the calming energy and long-term effects.

It seems that CILTEP has made enough with its 5 parts to be in progress with new and improved nootropics. Just that its actions are targeted around simpler goals, like learning and staying focused on your work.

The good thing about CILTEP is that it’s stackable with many nootropics, and can be upgraded.

Stacking CILTEP

Stacking CILTEP with other synergistic nootropic combo’s makes it more of an experimental stack for sure. Let’s find out some combinations that are anecdotally said to have the best effects.


Racetam family of supplements work to optimize interaction with glutamate and electrical signaling at the synaptic cleft while CILTEP optimizes the operation of secondary messengers inside the neuron by triggering long term potentiation (LTP) via adenylyl cyclase without activating the D1/D5 receptor which normally uses this pathway to enhance LTP.

Although complimentary, not all racetams will stack well with CILTEP.

Stack well

Possibly the best stack. Start with smaller doses of piracetam.

Does NOT stack well

Stack well

A bit too stimulative. Find a dosage and schedule that works.


Users report lethargy, lack of motivation, and over-relaxed sensations.

Some researchers say that ampakines are maybe the missing piece in CILTEP due to the fact how the late phase of LTP depends on NMDA receptors. Noopept is an ampakine that has good affinity to AMPA and NDMA receptors. The Sunifiram and Unifiram combo also work well for some individuals.

People have interesting effects when taking Noopept with CILTEP.  Some report they are just smiling and dancing in the shower while feeling happier and more out of their head. To quote Abelard Lindsay from one of the Longecity threads.

I’ve been taking Noopept with CILTEP lately. That and CDP choline for the uridine. This stack makes me almost too friendly and happy. It’s great. 


Natural stacks have great products that are synergistic with CILTEP, for example, their Smart caffeine stack. You might try it as this combo is many people’s favorite and might become your ultimate nootropic stack. Many others, including myself, drink it with Bulletproof coffee. Or just with an ordinary cup of good coffee.

Fish Oil

Some anecdotal reports say that a combination with DHA helps to maintain alertness. It’s unclear whether this effect is synergistic. I’ve had great results with cod liver oil and Now foods omega 3.

Can you do custom CILTEP stack?

Some nootropic fans don’t buy premixed or branded nootropics, because they think it’s a way overpriced. Instead, you can buy bulk powders and stack the individual parts for the best possible result and a cheaper price. 

Some people have found they need more/less, and sometimes NONE, of a certain CILTEP ingredient. Also, doing your own stack can mitigate the side effects you might have with some ingredients in the premade CILTEP stack. 

You can tailor your stack a little bit better that way and over time find the best ratios of ingredients that make you feel the benefits. 

Artichoke extract + Forskolin

Many neurohackers rapport that Forskolin in addition to Artichoke improves mood. Some even compare this combination with Modafinil, one of the most powerful brain enhancers. All the good things are:

  • Improved long-term memory
  • Increased ability to retain information
  • Increased ability to study
  • Improved mood and motivation

Does it sound familiar to you? The same ability that CILTEP has.

Intermittent fasting felled by ALCAR

While I’m sure you can find other creative approaches with CILTEP ingredients, if that’s really what interests you, this one has caught my attention.

Intermittent fasting is an eating pattern that cycles between periods of fasting and eating. For people that are tweaking the CILTEP approach that might produce great nootropic effects. One that is reported on Longecity forum shows great versatility and synergy that these ingredients can provide. 

Especially ALCAR which is a forerunner in this case. The important thing here is that it’s just a nutrient! Meaning, no tolerance build up. 

the CILTEP-effect while running on ketones in addition to glucose is just amazing… Indescribable. My focus just never stops. It’s almost ridiculous (today I studied for 10 hours… with one break).

This alternative method relies on ALCAR as needed assistant to fuel fatty acid oxidation and other ATP-producing processes during fasting. You need to take it immediately after wake up, as well as other ingredients. In this formulation, ALCAR is dosed 500 mg every 2 hours while fasting, and if you spend a lot of energy.

  • Zembrin (1x), Artichoke (1-2x500mg), Forskolin (5-20 mg active extract)
  • Caffeine Tea source
  • L Tyrosine – Wait with dosing tyrosine. Add it if you don’t feel anything.
  • Allosteric modulators, such as Piracetam and Phenylpiracetam.


Like with every nootropic stack, I would recommend taking CILTEP after waking up with your first meal.

Like most good nootropics CILTEP has a subtle effect and it’s not too strong for your biochemistry. You will be much more focused and productive and sometimes you will notice later that you’ve had a great time.

Exercise improves the effect of CILTEP, much more than other nootropics you can stack it with ( racetams, modafinil, etc). By exercising you will enhance the effects CILTEP has on your dopaminergic system and reduce the fatigue it may otherwise have.

It’s advisable you have to be 18 years old before you can start taking it.

final conclusion

It’s almost as if CILTEP will never grow old. These five ingredients are a trademark and are a unique representation of what a smart formulation might look like. Today’s supplements provide a much wider range of brain goals. Still, some of the best prepared nootropic stacks, such as the Qualia Mind mega-stack, contain CILTEP along with other ingredients. So, it’s flattering to this bunch and undoubtedly the creative formula it possesses.

I would say CILTEP is still great for a wider periods of focused efforts. Making use of this product will result in a supporting ability to feel efficient as well as determined. Made for adults working hard, CILTEP can improve mental focus, whether you require it at the office, in the house or at college. CILTEP activities concentrate on raising motivation and mental endurance, providing solid focus capability, maintaining long – term memory recall and also supporting mood and social skills.
