Some people think of piracetam as a risk-free drug. While some evidence suggests it is low in risk in comparison to certain other drugs, piracetam use carries potential risks. Read about its side effects and reviews in this article.

What is Piracetam?

Piracetam is the “original” racetam and is considered one of the most popular “smart drugs” or nootropics.

Although it is allegedly less potent than other racetams, people still take it to enhance cognitive function.

The racetam group of synthetic compounds is characterized and differentiated by their chemical structures that all contain a pyrrolidone lactam ring. Piracetam and other racetams like oxiracetam and aniracetam are considered cognitive enhancers or nootropics, while others like levetiracetam are used to treat epilepsy as anticonvulsants.

Unfortunately, there appears to be little proper clinical research with piracetam, especially in young, healthy volunteers.

However, there is some research on elderly populations with dementia, schizophrenics, and those suffering from neurodegenerative disorders caused by head trauma, stroke, and alcoholism.

Piracetam supplements have not been approved by the FDA for medical use. Supplements generally lack solid clinical research. Regulations set manufacturing standards for them but don’t guarantee that they’re safe or effective. Speak with your doctor before supplementing.

To find out about some of the uses and side effects of specific racetams, check out these posts:

Mechanism of Action

How piracetam works is not fully understood. It has been proposed to have several actions in the brain including [1]:

  • Activates AMPA receptors
  • Increases NMDA receptors
  • Increasing acetylcholine (ACh) receptor number
  • Enhancing energy metabolism – increased oxygen utilization, mitochondrial permeability, and cytochrome B5 synthesis.
  • GABA-like characteristics
  • Antioxidant properties

People popularly stack racetams are typically alongside choline donors (alpha-GPC and citicoline), as their mechanism is thought to deplete choline stores in the brain. No evidence backs up this practice [2].

On the other hand, injections of piracetam increase high-affinity choline uptake in the rat hippocampus [3].

Administration of piracetam has been shown to cause a decrease in acetylcholine levels in the hippocampus of animals. Piracetam and choline taken together have been shown to increase memory and cognition in animals. However, the effects of piracetam – with or without choline – on acetylcholine in humans are unknown [4, 5, 6].

Piracetam Side Effects & Risks

Keep in mind that the safety profile of piracetam is relatively unknown, given the lack of well-designed clinical studies. The list of side effects below is not a definite one, and you should consult your doctor about other potential side effects, based on your health condition and possible drug or supplement interactions.

Reported Side Effects

A study of 927 recent stroke patients taking 12 grams (a very high dose) of piracetam for 12 weeks reported no adverse effects from piracetam. However, this study was not designed to monitor side effects. Even more concerning is that this study noted that death within 12 weeks occurred more frequently in the piracetam group, but the difference from placebo was not significant [7].

Furthermore, in the group who had suffered a primary hemorrhagic stroke, the death rate in the piracetam group was half of that in the placebo group. This group was not large enough for this to be considered a significant result [7].

A longer study of 11 people for 18 months reported that 2 people experienced fatigue, but the study concluded that piracetam was well-tolerated [8].

In a study of 60 people who suffered a concussion, a daily dose of 4800 mg for 8 weeks reduced symptoms. However, side effects were reported by 64% of the patients under piracetam and by 32% under placebo [9].

The study reported that the following symptoms were more frequent in people taking piracetam than the placebo [9]:

  • Anxiety
  • Insomnia
  • Nervousness
  • Agitation
  • Tremor
  • Depression
  • Sweating

In 60 elderly psychiatric patients, the following side effects were reported [10]:

  • Insomnia
  • Mild dizziness
  • Overstimulation
  • Increased sexual activity

The study concluded that based on their impression, piracetam was well tolerated by most subjects. They stated that side effects disappeared upon discontinuation of the medication.

One study in 2015 looked at side effects of piracetam from a particular forum (drug-forum) and reported symptoms of [11, 12, 13]:

  • Restlessness (Psychomotor agitation)
  • Unhappiness (Dysphoria)
  • Tiredness
  • Dizziness
  • Memory loss
  • Headaches
  • Diarrhea

The study brought down a case report of a 17-year-old kid with OCD, who was stable on an SSRI. He went to the emergency room because his OCD got worse and he experienced restlessness and paranoia. Further investigation revealed that the supplement was piracetam. The parents had not objected to him using the supplement since they perceived it as a safe and “natural remedy.” He was discharged home after a short hospital stay in a stable condition on olanzapine at bedtime. Piracetam was discontinued.

This list does not cover all possible side effects. Contact your doctor or pharmacist if you notice any other side effects.

Call your doctor for medical advice about side effects. In the US, you may report side effects to the FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch. In Canada, you may report side effects to Health Canada at 1-866-234-2345.


Piracetam has anti-platelet activity, meaning that it might thin the blood. Therefore, it may interact with blood-thinning medication (i.e. warfarin) and increase the risk of bleeding. Caution is also advised in people with low platelets are low, those at risk of bleeding disorders, or going to surgery within 2 weeks [14].

Possible Mechanisms of Side Effects

The exact mechanism of the side effects of piracetam is unknown. The studies and pathways mentioned below are based on experimental animal and cellular findings. They have not been verified in clinical trials.

1) NMDA receptor

Piracetam activates AMPA receptors (allosteric) and increases the number of NMDA receptors. These receptors are also implicated in learning and plasticity [15].

However, activation of NMDA receptors has also been linked with anxiety, restlessness, irritability, insomnia, OCD, brain fog and a host of psychiatric disorders [16, 17].

However, NMDA receptors are complex. They may cause issues when over or under activated. Whether it’s good or bad might depend on where it’s located on the neuron (in the synapse or not) and what components the NMDA receptors have (GluN2B vs GluN2A) [18].

2) AMPA receptor

Faramptor is a molecule that is hypothesized to activate AMPA receptors (allosteric) in a low impact way, similar to racetams, and it can cause headaches, sleepiness, and nausea [19, 20].

3) Acetylcholine

Piracetam is thought to deplete choline (and therefore acetylcholine levels), which is why people also supplement with choline. For example, piracetam reduces acetylcholine in the hippocampus of rats. However, it’s unknown if piracetam affects choline levels in humans as clinical data are lacking [21].

4) Oxidative Stress

In rodents, piracetam increased oxidative stress in the hypothalamus with an equivalent human dosage of around 3.25 g (for a 68 kg person) [22].

5) Aldosterone

Some of piracetam’s memory-enhancing effects may be mediated by aldosterone/mineralocorticoid receptors. In theory, increased activation of this receptor may help explain the side effects of sweating, irritability and sleep issues from piracetam. However, this link remains unconfirmed [23].

Theoretical Risks

Very little is known about ampakines; the only example to reach human clinical trials as of 2014 is Cortex Pharmaceuticals’ CX-717, which was evaluated in Phase I for the treatment of Alzheimer’s disease. However, tissue damage was seen in animal studies and the FDA denied the application and the approval stopped (Cortex claimed this was not caused by the drug). None of the other ampakines is known to currently be in human trials, so little can be proven about their efficacy or safety in healthy individuals [15].

Racetams increase brain plasticity, but that may not always be good. Brain plasticity in the areas of the brain that affect emotional and mood functions could potentially lead to poor emotional regulation and impulsivity if plasticity is excessive and unregulated [15].

At first thought, increased plasticity might seem to be good, by improving learning and cognitive function. However, excessive plasticity could also lead to reduced synaptic pruning. Impairments in synaptic pruning are associated with autistic spectrum disorders. The excessive connectivity leads to heightened overall brain activation, but the reduction in the selectivity of activation. This can cause a lower signal-to-noise ratio [15].

Ampakines increase Long-Term Potentiation (LTP), but increased LTP could lead to impairments in spatial memory and perhaps motor function [15].

One study explaining the theoretical risks of racetams cautions young adults against taking ampakines because it might interfere negatively with development [15].

Side Effects Reported in Forums

The following case reports of piracetam and other racetams have been mentioned in internet forums:

  • Brain fog
  • Sleepiness/drowsiness
  • Irritability
  • Sleep issues
  • Depression
  • Muscle twitching
  • Headaches
  • Sweating
  • Cognitive problems (issues with reading, spelling and verbal retrieval)

Anecdotally, people take the following supplements to reduce the side effects of piracetam:

  • Alpha-GPC – to replenish choline stores
  • NAC – to prevent oxidative stress to the hypothalamus [24, 25] and to reduce glutamate/NMDA receptor over-activation.
  • Magnesium – blocks NMDA receptors
  • Theanine – blocks AMPA receptors [26]

The effectiveness and safety of these supplement combinations are unknown.

Responding to Criticism

Critics of this post argue that you can find negative reports about any drug or supplement. This is true, but for some reason, piracetam is seen as a side effect- and risk-free substance.

Also, the reports center around brain fog, which is rare for case reports, while something like nausea is pretty common.

Another critique is that the case reports are meaningless because there are many studies that show it’s safe. However, the scientific and medical community agrees that we can’t know if something is safe based on data from animal studies and a few small human trials.

People in the nootropic world tend to assume that piracetam is just as safe as vitamin C, if not safer. The goal of this post is to show that this may or may not be the case, and caution should be taken with a drug like piracetam, which is considered to have a low-risk profile compared to some other supplements.

1) “Piracetam makes me depressed or more irritated” [27].

2) “I am not convinced that the headache from Piracetam is caused by Low choline levels because from the first time I took piracetam I got a headache from taking a few extra caps and I really doubt my choline levels were that low right when I first start” [28].

3 & 4) “2 separate users took piracetam for a few months and experienced cognitive dysfunction” [29, 30].

5) “I took piracetam for 2 weeks and I now have muscle convulsions randomly, at different places of my body, at random times. Sometimes twice in a minute, other times twice in an hour. It only lasts for a few seconds. I only took it for 2 weeks and the side-effects have been present for the last 3-4 months. I don’t think it’s going away… eh” [31].

6) “I’ve stopped using piracetam, and I still experience some brain fog as if someone is putting pressure on my head… Will this go away?” [32].

7) “I was on piracetam for 1 month and stopped it suddenly. Now I feel like I can’t do anything (driving, writing, thinking). It f****d up my brain” [31].

8) “I have used piracetam 5 g/day for two days now and what I feel is the following: slight nausea, brain fog, lower scores in luminosity (brain) games, slight pressure in the frontal lobe, maybe” [32].

9) “I started by taking an 800mg dose 3 times a day for the first 3 days and nothing happened. I pushed it up to 1,600mg 3 times a day and I got the worst headache of my life accompanied by brain fog and nausea.” [33].

10) “When you first start Piracetam you will get brain fog and have trouble reading, I noticed this as well as I recently started taking it again…” [33].

11) “How can you reduce piracetam brain fog symptoms?” [34].

12) “From my 10+ years of personal experience, I have found that many times Piracetam made me sleepy, and/or I got severe brain fog. I have tried it at dosages from 800mg up to 4,800mg (attack” dosage) per day, both with and without choline (either Alpha-GPC, Citicoline, or Phosphatidylcholine in dosages from 300mg – 1,000mg per day). I have also taken it with Hydergine (up to 4.5mg per day), and I have also tried Aniracetam, Oxiracetam, and Pramiracetam with similar results. I have also tried different brands of Piracetam from Nootropil to Primaforce. I also don’t use any recreational drugs, other than a glass of beer or wine a few nights a week, I get 6-8 hours of sleep a night, and I have no psychological conditions (i.e. bipolar, depression, etc). I have a job where I need to maintain alertness and clear thinking 8 – 10 hours a day, so I can’t afford self-induced brain fog. I have always taken nootropics on faith, thinking that they were somehow helping me, even if I didn’t notice any effects. I’m now starting to think that in order for a nootropic to be called effective, you should be able to notice a positive result within a reasonably short period of time (none of this “you need to try it for 6 months before you notice a result”). I am also starting to believe that in order to be called an effective, a nootropic like Piracetam should never make you feel worse. I was sitting there one day in a Piracetam induced fog, thinking to myself that I paid money for this result” [35].

13) “Piracetam is neurotoxic to me, feel more stupid than the previous year”[35].

14) “My own view would be piracetam makes depressed days worse but upbeat days better” [35].

15) “I was taking Piracetam 1,000 mg twice / day for a month (Prima Force), then I stopped taking it 5 days ago, and I now feel like I am zapped of creativity, and I also feel really dumb. I am making basic spelling errors, and I am having trouble formulating thoughts, and feel like I’m really straining to think. My thoughts were fluid before I started taking it. Is this normal? Is this something I should be concerned about?” [36]

16) “I just got in piracetam yesterday. Tried 3x 800mg yesterday with good effect (I didn’t try to do any work, but felt a lifting of brain fog as with Adderall.)

I woke up after a full night’s sleep with the worst brain fog of my life. Tried 800mg this morning, brain fog intensified. Took lecithin, brain fog intensified. Took another 800mg piracetam ~4hr after the first dose, brain fog even worse. Now at 8 hours since the first dose, I can finally concentrate enough to read again. Has anyone experienced these effects so early on, and gone on to have good effects later? Is Piracetam just not likely to work for me? I’ve got noopept coming in later this week, maybe that will go better” [37].

17) “Personally, piracetam gives me brain fog, with or without choline. I definitely feel something, but it’s not very good” [38].

18) “I find that 400mg – 800mg work best most days, then some days I’ll have to bump to 3.2 g, just for that one day, then the 400mg – 800mg doses work well again. If I do another 3.2g that same day (or even the next day), it results in brain fog” [38].

19) “Interesting article, piracetam didn’t work for me either and I have written similar reviews as in the article online. Some people truly don’t understand what you mean and tell you to take more or something like that. It could very well be that it does nothing at all in most people and the effects are imagined or even real depending on your brain chemistry but I would avoid speculating about the intelligence levels of these people” [38].

20) “Anecdotally, I’m clearer-headed on days I forget to take my racetam dose (PAO stack) [38].

21) “So I ordered some piracetam a while back from bioscience neutraceuticals, I got the package on Monday, and began taking it on Tuesday.

It doesn’t work, and not only does it not work, it actually gives me brain fog, and makes me tired. I ordered CDP choline and sulbutiamine (wasted about $168).

I’ve varied the doses, taken it without choline, taking 4.6 grams, taken .8 mg, taken it with Fish Oil, and every single time, the same brain fog, the same effect.

Now, I’m not trying to sound like a douchebag, but I’m a relatively smart kid naturally. I read all the bs anecdotes on here, and even some of the published studies, and decided to give it a try. I don’t know if it just has an opposite effect on healthy individuals who have brains already functioning pretty well, or what, but this stuff just absolutely sucked for me.

Just wanted to share my experience with anyone else who notices this and keeps trying in hopes of some kind of cognitive edge.

Things I felt

1) Tired
2) brain fog
3) reduced reading speed, and if I attempted to read at my normal pace, I would get words jumbled up

I’m sure that MAYBE (presuming it is not a placebo effect) it works for some people, but if you feel these within the first week of taking it, after titrating doses and doing everything else people recommend, I recommend just throwing it out and calling it a day” [39].

22) “Hi, I’ve been using piracetam for one month now. Always 800mg in the mourning and 800mg in the afternoon. Since last week I’ve added 600mg of choline citrate in the mourning. However, since then, I started getting brain fog sometimes. Brain fog is some very very light feeling of pressure on your head and also a weird feeling of not being able to concentrate well, no clarity. Also, a bit sensitive to light.

So Monday I took my last dose. Now we are Wednesday and I’m still experiencing the brain fog… It scares me.

I also drank alcohol with the piracetam on the weekends, but not very very much. (like 8 beers every Saturday or so)

What should I do?” [40]

23) “I started taking Piracetam back in November last year for various mental issues I was facing; including chronic fatigue (unrefreshing sleep), ADHD (Inattentive type) or ‘brain fog’, mild depression, and Aspergers Syndrome (maybe). Let me tell you that for the 7 months I was consuming Piracetam, it changed my life and all of these symptoms I suffered from were truly eliminated. This all lasted the best part of 7 months and I was taking 2.4grams/3 or 4 times a day. I was supplementing with CDP-choline for the first few months to counteract my initial headaches, but stopped after I read (and realized) that I didn’t need it.

… About two months ago Piracetam’s magical abilities stopped working (even though I was maintaining my normal doses) and all the horrible symptoms came roaring back – the depression, absent-mindedness, brain fog, and the lethargy…I used to only need 6 hours sleep a night, swallow 2.4 grams of Piracetam in the morning and be full of so much energy and life. Now I’m sleeping up to 12 hours and I feel like crap – I’m so drained, anhedonic, and absent-minded… even though I’m maintaining doses. Hell, if anything, Piracetam seems to have the opposite effect nowadays – it makes me more tired and unfocused when I actually do dose” [41].

24) “Here’s what I’ve tried taking:

1.6g Piracetam

Effect: Nothing? Maybe a bit of brain fog? Was my first time ever taking it.

800mg Piracetam

I think I experienced what people call “brain fog.” Took it and then I ended up napping for a bit. Felt extremely lethargic and ineffective. I took Choline Bitartrate beforehand” [42].

25) “Now, after a year of piracetam supplementation at 2,400mg twice a day (morning & evening), getting off for 6 months and getting on again,

I discovered that it causes a familiar slowness and brain fog to a certain lower degree, WITH OR WITHOUT choline (tried CDP choline, alpha GPC, and ALCAR).

These days I often find myself in the basement/fridge, having no longer a clue what I’m looking for + I was at a quiz recently and had to think WAY too hard.

I’m pretty much done with piracetam because of these findings.

I did like the positive effects of piracetam a lot, but there’s definitely something going on with brain fog / short term memory as well.

It’s as if my brain sometimes gets ‘lost'” [43].

25) “My piracetam arrived just a short while ago, so I took 600mg at midday Friday, 1200mg half an hour later. Saturday I took 1,200 mg at about 2 pm. I took no dose on Sunday due to concern about side effects.

The effects I noticed in chronological order where that: Friday evening my orgasm was weaker than usual, less cum. I had an unusually wonderful dream that night. The morning after, same thing weak almost dry orgasm.

Later in the evening, I noticed that a muscle was contracting wildly, something in my wrist was jerking rapidly. After about half a minute it disappeared. Then it came back and disappeared a few times.

That night, same sexual problem. Dreams were normal.

Next (Sunday) morning same problem.

Had some intermittent twitching in the afternoon, but sexual function was restored in the evening” [44].

26) “This morning I took my first dose of piracetam and CDP choline (1.2g and 300mg). I have taken piracetam on one previous occasion, with a fairly good response. I have no history of mental illness and I don’t take any drugs or medication.

Shortly after mixing the two substances in a glass of water and drinking them, I experienced a feeling of pure terror. This episode lasted for almost 2 hours during which I could barely communicate or think. I had gone for a walk after taking the piracetam and it took most of my willpower to remain composed.

I do not exaggerate when I say that this has been one of the worst experiences of my life. It’s now been an hour since the feeling subsided and I’m left feeling drained with mild brain fog (which is subsiding steadily)” [45].

27) “I am trying to continue using Piracetam but I find it always gives me brain fog, even minute quantities of Piracetam with mega doses of Alpha GPC and/or Lecithin. I believe it is the fact that I stacked it with so many things that I no longer get the pure effects (I’m uncertain if this is psychological or biological) I got in the beginning nor any of the results everyone else is preaching

Previous Stacks alongside Piracetam:

DMAE (after that it all went downhill leading me to theorize that DMAE has anticholinergic properties like believed or does when taken on and off too many times)

ACh precursors (went from regular Choline bitartrate to A-GPC to Lecithin)

Aniracetam (made things much worse)

Hydergine [which is the only good combination with Piracetam (nootropic wise) there is IMO]

Alongside herbal regiments (from stimulants to clarity enhancers)

I thought I needed to attack dose once more and when I did so I got such a massive headache the likes which I have never felt before in my life lol

I now find it intensifying OCD type behaviors, resulting in Brain fog no matter how much ACh I take with it.

It works perfectly during its half-life point though overproduction of Alpha waves (measured by neurofeedback EEG). I have tried getting off of it for a period of a week and returned to it today (with a dosage below 200 mg) to see if anything happened, subsequent brain fog (though combined with rhodiola rosea)” [46].

28) “Just got piracetam today. I only took 400mg, but I felt very sleepy after an hour or so. It lasted for about 3-5 hours” [47].

29) “I have experienced this as well, not always exactly sleepy but often a bit tranquil and a sensation familiar to when you recently receive a lot of new impressions. A kind of fatigue” [47].

30) “I was hoping I could get some help classifying some symptoms, and possibly solving them. I’ve been having trouble speaking recently, whether it’s on the phone, or in public. I don’t know if its anxiety or brain fog, but I’ll have difficulty actually saying the words, while knowing what I may want to say. I don’t stutter per se, but I just have trouble speaking properly. This is new, and I’m in my late 20s. It’s been happening now for a month or two.

What I’m taking:

Piracetam 1.6g

Picamilon 150mg

ALCAR 300mg

Fish Oil 900mg

Is it possible anything in my small stack is causing this? Any thoughts on a resolution?” [48]

31) “So I decided to start on my quest for mental glory. I kept reading how Piracetam is so safe that people should probably change the word “safe” itself to “piracetam”. Anyway…I’ve been taking it for three days now.

Day One: 1200 mg and three whole eggs

Day Two: 1200 mg and three whole eggs

Day Three: 2x2400mg and 2x 250/250mg Choline/Inositol. At the end of Day Three, I almost got a panic attack. I’m not sure why – mostly due to stomach uneasiness and weird mouth feeling. The roof (palate) was numb and somewhat rugged. I managed to calm myself down, no panic attack. And got to sleep. Pupils were constricted I think. Now, most people will tell you how piracetam makes your sleep a wonder. You get up all refreshed and everything, willing to conquer new heights, etc. Well, guess what. I slept for over 12 hours and when I got up I felt even more tired than the night before, the palate still tingling, and somewhat nauseated. Mildly depressed and rather irritable. I hated it. Actually, as I’m writing this I still feel nauseated a little bit.

What do you think is that all about? This is just the start of my nootropic quest, I was looking forward to much much tougher stacks and now I crumbled at the very basic one. Don’t know what to do” [49].

32) “I just got 100 caplets of Nootropil 1200mg from overseas.

This morning I took my first dose of 2 caplets ( 2400mg) and felt sleepy.

Is it normal for the first dose?

( I’ve been taking a very sedating antidepressant Avanza 90mg, Klonopin 2mg, for the past 4 yrs at nite…….and I got a tolerance to their effects……sometimes they even don’t sedate me anymore..)

Strangely, as I know, Nootropil is more of a stimulant type, unlike Avanza or Klonopin. But why does it give me a sleepy feeling……is it called as the term ‘Brain fog’?

Maybe I should take a form of Choline with it. (usually, I buy Lecithin granules.)

Is there anyone experiencing this effect for the first time without Choline? Is it called ‘Brain fog’?” [50]

33) “Same experience [Brain Fog], even I have stop Piracetam more than a month still have that exp, I in very serious situation don’t know how to do next, know any sup can help me” [51].

34) “I’ve started taking piracetam capsules, 800mg once a day with 2 x 300mg alpha gpc yet I all day I get a slight headache, last night I even had to take 500mg paracetamol to sleep. I always have two eggs for breakfast and drink a glass of milk during the day.

Yesterday was the first time I began this schedule but I have tried before and had a bit of brain fog.

The day was generally good, I felt confident and very alert, everything was very colorful too. I “crashed” at around 2 pm and had brain fog, I took another coffee (the first one being my morning coffee) and BAM back in business.

Thanks for all the help. I’ve had no headaches since, however, today has been awful in its own way.

I’ve only taken 800mg piracetam and no choline supplementation. Eggs for breakfast and 2 coffees with milk.

I’ve felt a lot of brain fog, irritability and been sweating a lot from the palms of my hands.

Really feel as though I cannot go through with this even till the end of the week. Might try reducing my piracetam intake tomorrow depending on how I feel when I wake up.

No depression but slight anxiety. Fluidity of speech is still good and I’m able to read for lengths of time but I’m getting distracted by thoughts of how it isn’t working too often.n

I felt last night very emotionless for a couple of hours too” [52].

35) “The major downside is that after about 2 – 3 days (taking 1440mg 3x/day), my memory retrieval goes way down to the point that I forget simple things (feels like dementia), it’s like my brain processing speed just takes a nosedive. I also become very aloof like I am not even there with this like blank stare on my face, just really really spaced out I guess. The thing is that even DMAE (although it enhances my concentration) will space me out as well, just not as bad as piracetam. I do not notice any physical symptoms, but I will get a pretty bad headache if I take it with ashwagandha. I’ve tried taking it with choline citrate and also tried taking it with bulk nutrition’s alpha-gpc 50% mix. I have tried taking the piracetam and choline along without taking other supplements to try and pinpoint the problem, but to no avail. I’m totally lost on this” [53].

36) “After this, I looked to achieve the same effect from CDP choline. Although I did get exactly the same results (more energy, better hair, face color, libido, no eye-bags) as soon as I started experiencing the exact same background anxiety as on Alpha GPC so I was forced to discontinue this as well as it significantly impaired my social abilities. From there on I set off to search for another nootropic and this is when I came across noopept. Love at first sight. Noopept made me a happier, smarter more sociable and charismatic person. I continued dosing it on its own (15mg on mornings) for around a month. While on noopept I had the motivation and zest for life that I had been looking for to carry out all the long-term projects I had planned for myself. It’s important to mention that while on noopept there were some days where I still tried phenibut and on a two separate occasions Inderall.

Towards the end of my love affair with noopept, I started experiencing a host of several symptoms. The first symptom came up one afternoon with my girlfriend, where I experienced erectile dysfunction and in the next weeks I started to experience a host of other very alarming symptoms, including:

-Lack of circulation to my hands and feet

-Itchy back

-Digestion problems to the point of constipation

-Easy bloating

-Lack of motivation

-Impaired ability to think and speak (brain fog)

-Pale face, bad hair, bags under eyes – generally looking much older

-Complete loss of libido, loss of feeling, and ability to achieve and maintain an erection.

-Susceptible to flu’s and infections and difficulty healing

-Loss of muscle

-Inability to do sports

This alarmed me to cease all nootropic and supplement use. Given some of the symptoms initially, I was convinced it was a kidney problem. But after a medical check-up, this theory was dismissed. I gave myself a month to see if everything would return to normalcy on its own – but unfortunately, that didn’t happen. Some of the findings I gathered during that month: If I would try taking noopept or piracetam (tried once) I would still feel great effects from it. But my body would shut down its ability to achieve an erection. I would lose all feeling and sensitivity down there. As if my body lost its ability to relax in that sense. I would also feel discomfort on my lower back where my adrenals/kidneys are located. Any type of sports would make me too fatigued and looking tired and worn out instead of energized – sensitive to all chemicals or supplements even coffee makes me shaky and anxious (NE effect?). Adaptogen herbs stimulate me way too much (they give me crazy libido but right after it goes back to normal) and I’m left with a hangover effect” [54].

37) “Ok, before I begin… Yes, I have searched all over the forums regarding my problem; however, I have yet to find any solutions.

SUMMARY: I’m getting brain fog (a side effect, I’m under the impression, that is normally due to Choline) from supplementing Piracetam regardless if I add Choline or not.

I first started taking Piracetam about 6 months ago. I originally purchased pills that had the racetam and choline mixed. I would have inconsistent results varying between headaches and brain fog. This led me to purchase bulk powders of the two so that I could experiment with exact, measured doses.

For the first couple of weeks, I experimented with different doses, and I found that 3-6g of Piracetam with little to no Choline was ideal. I was having superb effects; fluid thinking and talking, sharper memory, and felt overall great.

However, after the first couple of weeks, the positive side effects vanished, and I have been left with brain fog and laggy thinking (when I consume the supplements). I’ve tried every combination of Piracetam/Choline. I’ve tried every suggestion I’ve found on the forums; Calcium, Fish or Krill Oil, B-Vitamins, ALCAR, Green Tea, etc. No matter what combination/stack I try, as soon as the Piracetam kicks in, I get some intense brain fog and laggy thinking for the duration of the time that the Piracetam is active/working” [55].

38) “Okay, so this is my story. I started taking choline and piracetam about a week ago. For the first 5-6 days, I experienced the most amazing positive effects (especially when combined with caffeine).

I was taking the following daily doses:

250 mg choline bitrate

800 mg piracetam, 2-3 times a day (roughly every fourth hour)

The effects were as following:

Visualizing music a lot easier, feeling the music deeper

Clearer thoughts

Awake, more energy

Mood boost

confidence boost – reduction in anxiety (hitting more ‘naturally’ on girls, for instance)

emphatic abilities – feeling other peoples emotions a lot deeper

Nature/the sun seems more beautiful – visual enhancements

Greatly improved concentration!

Easier to recall past memories

Greatly improved verbal abilities. Communication seems a LOT more fluid, with no ‘pauses’, due to not recalling the words I wanted to throw into conversations.

– Overall, I felt like an improved version of myself.

For the first day, I took the piracetam without the choline. With or without, I didn’t feel much of a difference.

The only negative effects I felt from the piracetam, was maybe a ‘crash’. When I stopped dosing in the evening, and my last dose (four hours later) would fade away, I would feel very tired.

However, on the sixth day, I barely felt any of the piracetam effects. The effects were diminished like 90-95%. I tried taking a huge piracetam dose, like 4,8g, instead of 800mg, which felt like a weak piracetam dose, but still, nothing, compared to the effects of the first 5-6 days.

I’ve also tried taking a huge choline dose, like 1g, together with 800 mg piracetam, which also seemed to boost the effect a bit, but still way weaker than in the beginning.

Now I’m sitting here, like eight days later, and all I’m getting from the piracetam is tired brain fogging feelings, which is pissing me off. It worked like a wonder drug in the beginning, but like sh*t now…” [56].

39) “Hi there, sorry for this post but I am really angry, I spent a lot of money already, I bought Fish Oil, Noopept, Aniracetam, and choline cdp.

(1st Attempt) I started taking Noopept 20mg a day for 2 weeks, nothing happened, only a terrible headache and fog brain.

(2nd Attempt) I started taking Aniracetam + Choline Cdp every day for 15 days, again, nothing happened, but no headaches.

(3rd Attempt) I have been taking Noopept + Choline CDP for 1 week already, nothing happened, only fog brain, but at this time fewer headaches…

So I spent more than f***ing $100 already and the only thing I noticed was a better mood, but only because of the Fish Oils I am taking…So, in fact, I am starting to think that these products don’t work at all…Please, I need a light for this problem, I am studying for the Cambridge CAE exam and till now these products are giving me more problems. I need something that can be effective… Any suggestions? Thanks!!

Roger, Sydney/Australia” [57].

40) “I read all that “piracetam is the safest drug imaginable – only positive effects”. My experience says: bullsh*t. Seems my brief acceptance of a chemical has come to an end. I guess I’ll only keep my phytonootropics” [30].

My experience (on an 800 mg or 400 mg dose):

  • Numbed emotions – check
  • Very good anxiolytic effect/lack of social anxiety (better than drinking a couple of shots) – on the first two days
  • Absolute drowsiness/sleepy-headedness to the point of not being able to function and HAVING to sleep it off;
  • Waking up with/ feeling a scary numbness of limbs (foot, arms… and brain?? It’s what I feel.) – this has been a bad enough red alert to prompt me to enter this forum.
  • Shortness of breath, and waking up with the impression I wasn’t breathing enough/properly – I actually almost stop breathing if I don’t pay attention to my breath;
  • Strong sexual enhancement – on the first two days
  • Mild memory benefits on long-forgotten memories (weird, not very useful, but was OK)
  • Slightly augmented perception – brighter vision and accentuated smells – on the first day only, except the brightness (which is not very positive anymore);
  • Mild/slightly serious depression (on second and third day – today – and seemingly getting progressively worse with every dose) – never had to struggle with that sh*t anymore since I solved myself on the first years of my adulthood; I feel dumb as hell for trying a minimum dose a few hours ago, as I had cleared myself of the drug-induced depression after waiting if off for a long time;
  • Distortion of experience of time – closed my eyes in bed, and “a month/week” was experienced in 5m of clock time (second day). This experience was normal, that day.
  • Inhibited abstract reasoning (big time) – check (1.6 g dose)
  • Continuously lost simple terms to the tip of my tongue (verbal fluency seems to have been restored after I stopped) 1.6 g dose
  • Forgetting about trivial stuff such as where I left my keys, etc – check 1.6 g dose
  • Felt like a moron struggling with relatively simple tasks – check 1.6 g dose
  • Apathy/Zero motivation (I don’t give a f…/meh…/what am I doing here attitude) which deeply hinders me wanting to do my work, instead of the opposite 1.6 g dose
  • Inability to concentrate on a task AND GET MY JOB DONE. HOW HARD IT MADE FOR ME TO FOCUS AND PRODUCE!! 1.6 g dose and continued after, while less pronounced

And that was MY experience with piracetam. For me too, “It was my first (and probably last) [chemical] nootropic to use”. Much more bad than good came from it. It’s the third day since I’ve tried it and I can’t function even as properly as before [58].
