What is Phenylpiracetam?
Phenylpiracetam is a phenyl derivative of piracetam which is reported to be more neuroprotective compared to the original compound, due to its enhanced ability to cross the blood–brain barrier and bind to receptor sites.
What is Phenylpiracetam Used for?
Phenylpiracetam may be used for the following applications:
- Excessive intellectual or physical overloads;
- Mild depressions;
- Chronic fatigue syndrome;
- Cerebrovascular diseases;
- Alcohol hangover symptoms;
- Other conditions, characterized by reduced intellectual productivity.
Phenylpiracetam is used by healthy individuals experiencing various kinds of stress. Besides, its moderate activating effect on motor reactions, and physical performance can also explain the fame of the substance among athletes in sports.
More detailed information about the studies on the application can be found in the Research tab.
What are the Benefits and Effects of Phenylpiracetam?
Phenylpiracetam is claimed to have several effects:
Memory and Concentration
Some claimed effects of Phenylpiracetam include better memory, improved concentration, and quicker learning.
Antianxiety
Phenylpiracetam is also believed to work as mood-lifting and anxiety reduction supplement.
Is Phenylpiracetam Safe to Take?
Phenylpiracetam is not recommended for children, pregnant, lactating ladies due to the lack of clinical research data, and patients with individual intolerance.
With caution: Patients with severe liver and kidneys diseases, severe arterial hypertension, severe atherosclerosis, previous panic attacks, and acute psychotic states accompanied by psychomotor agitation (due to the possible exacerbation of anxiety, panic, hallucinations, and delirium), as well as patients prone to allergic reactions to nootropic drugs of the pyrrolidone group.
Certificate of Analysis
FAQ
Does phenylpiracetam cause insomnia?
Phenylpiracetam can cause insomnia or sleep disturbances, especially if taken after 3 p.m. As a stimulating nootropic, it increases alertness and energy, so it’s best taken in the morning or early afternoon to avoid interference with sleep.
Does phenylpiracetam increase dopamine level?
Phenylpiracetam increases the content of dopamine, as well as noradrenaline and serotonin in the brain. These neurotransmitters are associated with motivation, focus, mood, and energy levels, which explains the stimulating and mood-enhancing effects of Phenylpiracetam.
How long does phenylpiracetam last?
Phenylpiracetam typically lasts about 4 to 6 hours. Onset is relatively fast, within 30 to 60 minutes, and it’s often used as a short-acting performance enhancer for mentally or physically demanding tasks.
How is phenylpiracetam different from piracetam?
Phenylpiracetam is a piracetam derivative and is considered to be more potent and more effective. It is also used for a wider range of indications.
What is the Dosage of Phenylpiracetam?
Phenylpiracetam doses may vary between 100 mg and 300 mg.
The most common Phenylpiracetam dose is 100 mg taken once a day, every morning after meals. The usual Phenylpiracetam course duration is from 2 weeks to 3 months, on average 30 days. The nootropic supplement should not be taken after 4 pm.
One pack of Phenotropil (Phenylpiracetam) contains either 10 or 30 pills, each with 100 mg of the active ingredient. If you buy Phenylpiracetam 1 pack (30 pills) it will be sufficient for 30 days of administration.
What are the Side Effects of Phenylpiracetam?
Phenylpiracetam may cause psychomotor agitation, hyperemia of the skin, warm flashes, and hypertension during the first 1–3 days of admission. If Phenylpiracetam is taken after 3 pm, it may cause insomnia.
In patients with severe psycho emotional exhaustion, Phenylpiracetam may cause drowsiness.

I have used Piracetam for many years, Phenylpiracetam impresses me with being able to provide the same cognitive benefits at a much lower dosage. There is also a notable boost in energy and mood. No stimulant side-effects, just a gentle lift. I take this once a day. I like it a lot.

OVERPRICED BUT STILL GOOD
This product is effective but overpriced for what it offers. If you\'re expecting an Adderall or Modafinil-like boost in focus and motivation, this isn\'t it. It does work to some extent, but keep your expectations realistic. I only purchase it because they are one of the few reliable sources for phenylpiracetam. However, the quality doesn\'t match what Nootropic Depot offers, and the pills are noticeably smaller than they were a year ago.

Study, Study, Study....
I used to buy this product from Health Naturals, but they discontinued it a few years ago. Back then, I was using Phenylpiracetam Hydrazide, and it worked exceptionally well for me. I took it during my 12-hour shifts to stay productive, and it was so potent that a single dose could keep me going for almost 24 hours without feeling fatigued. One of the biggest benefits I noticed was the mental clarity, especially in my speech—I didn’t mumble as much, and I felt more articulate and motivated. Normally, putting my thoughts into words can be taxing, but this really helped smooth that process. Fast forward to today—I’m now in nursing school and had completely forgotten about this nootropic until recently. After some searching, I came across this website. I was a bit disappointed because a few years ago, Health Naturals offered much larger quantities at a lower price. If I remember correctly, I could get 60 to 120 capsules for what now gets you only 30, and at triple the cost. That said, this brand is just as good—if not better—in terms of quality. One pro is that the Hydrazide form doesn’t give me the euphoric or \"high\" feeling that Phenotropil sometimes did, which I prefer for focus and studying. I’ve been using it consistently for about six months now, and I’ve noticed my tolerance has definitely increased. Depending on my workload or how little sleep I’ve had from school, I sometimes need more than I initially did. Overall, while it’s really expensive, the quality is there—I just wish the pricing and quantity were more like they used to be.

Real
Came extremely quickly. Used it as a titration for Adderall for hypersomnia. I would say that the effect of this drug is like a milder version of modafinil, which is pretty amazing for something you can get without a prescription.

Very potent
Phenylpiracetam is a very potent nootropic. It's very stimulating and works well. However, it must be cycled properly to keep its effectiveness up. You will also need to supplement with Cognizant for a choline source. Personally I prefer the effects of Aniracetam from past experiences. So I will try and order some of that next time. Thanks

The tablets I got from this pharma brand were slightly larger with a score down the middle if you wanted to split the dose in half. It was helpful, but these new batches dont have that score anymore.

Hi Nicholas! Thanks for your feedback! Although the tablets may look different and no longer have the score line, please be assured that the formulation has not changed, so the dosage remains the same.

Excellent Product, Excellent Company
Phenotropil is my go-to nootropic, hands down. It delivers unparalleled clarity and mental speed—far surpassing Piracetam. I stack it with Alpha GPC twice a week, making sure to space out doses to prevent tolerance buildup. On alternate days, I stack Noopept with Alpha GPC, which comes close to the same effect. Since Phenotropil is difficult to find in the U.S., Cosmic has stepped in with the best (original) formulation. Their lightning-fast shipping and stellar customer service make them a standout. I truly can’t recommend Cosmic Nootropics enough—they’ve earned my loyalty for life
