Gabapentin aka Neurontin – is an analog of GABA (Gamma-aminobutyric acid) and it has been sold as a medicine since 1993. It is also used as a recreational drug. It is often used with Phenibut. People usually call them GBP (Gabapentin and Phenibut), or GPP (Gabapentin and Phenibut powder).
I would like to start this article by saying that Gabapentin is not the same as Phenibut. Although they are both analogs, Gabapentin doesn't have an affinity for GABA receptors at all.
I'm going to show you how Gabapentin works in your brain and why it doesn't have any effects on GABA receptors.
Phenibut on the other hand does have an affinity for GABA receptors, which means that the substance actually binds to the receptor molecule, blockading it from binding with another molecule.
This is how Phenibut produces effects. It doesn't bind with every GABA receptor, but just the ones that are responsible for anxiety, sleep, memory, and sedation.
History of Gabapentin
The first clinical use of Gabapentin was in the early '90s as an analgesic (pain reliever), and anti-convulsant. It achieved a lot of popularity when it was found to be useful in the treatment of epilepsy and neuropathic pain.
Gabapentin is not approved by the FDA for any indications yet, but it has been granted orphan drug status since 2003 due to its potential as a treatment for epileptic children with Dravet Syndrome.
Its orphan status means that pharmaceutical companies have to conduct research in order to get FDA approval.
History of Phenibut
Phenibut was developed by Russian scientists in the 1960's. By the early '70s, it was already in use as a sedative, painkiller, neuroprotective and anti-alcoholism medication.
It remained a popular medication for a long time until its popularity began to fade out in the '80s due to liver damages that were reported as a result of phenibut consumption.
Around this time there was also an outbreak of synthetic Phenibut analogs on the market which led to many negative experiences among people who were using them.
The negative experience led to a further decline in the popularity of phenibut because people believed that all products containing phenibut could be potentially harmful and lead to liver damages.
Fortunately, modern scientific research has shown that only certain types of phenibut analogs are dangerous and can cause liver damage.
Phenibut has been proven effective for many conditions both emotional and physical:
Anxiety disorders
Depression
Posttraumatic stress disorder (PTSD)
Pain management including neuropathic pain (nerve pain)
Insomnia including sleep apnea (respiratory pauses during sleep).
The use of Phenibut for any of these purposes has not been FDA approved yet, since it's only an analog of GABA and has no affinity for the GABA receptors. At this point, there is no way to know how safe it is.
Here are some well-known side effects of Phenibut:
Stomach discomfort or pain
Liver problems such as jaundice (yellowing of the skin)
Nausea and vomiting have been reported to be very common with Phenibut consumption. It's possible that these side effects are really related to the Diazepam contained in the phenibut tablets sold on the market.
However, it's well known among users that phenibut can cause nausea and even vomiting when dosed at higher doses than usual, which means that people who consume phenibut should start with a lower dose.
Phenibut vs. Gabapentin
Phenibut and Gabapentin are not the same, but they are often used in the same cycle. It has been shown that people who use Phenibut regularly can build a tolerance very quickly.
They usually need to increase their dosage to experience the same effects as before.
Gabapentin is sometimes used in a Phenibut cycle because of its ability to reverse tolerance and reduce withdrawal symptoms and cravings.
Gabapentin affects GABA A receptors in a similar way as GABA itself does. It binds to the receptor molecules without activating them and blocks them from binding with another molecule, which means that Gabapentin doesn't produce any effects on its own.
The main reason why Gabapentin is useful as an additive in Phenibut cycles is that it enhances GABAergic effects by increasing the affinity for the GABA receptor of other molecules such as Phenibut, alcohol or benzodiazepines for example. It does this by enabling Phenibut to bind more easily with the receptor molecules.
Using Gabapentin and Phenibut together in the same cycle can minimize tolerance, improve sleep quality and reduce anxiety. It can also be used as an alternative to other medication that is responsible for liver damage.

In today's fast-paced world, the demand for cognitive enhancers that can improve focus, alertness, and overall mental performance has grown exponentially. Adrafinil, a wakefulness-promoting agent and nootropic, has gained increasing attention for its potential cognitive benefits.
Initially developed in France, Adrafinil (also known as Olmifon or CRL-40028) is a prodrug for Modafinil (Provigil), another well-known cognitive enhancer. Both substances have been used to combat various sleep disorders, such as narcolepsy.
They have been explored for their potential applications in a wide range of cognitive disorders and conditions requiring enhanced mental performance. This article aims to provide an in-depth overview of Adrafinil, delving into its chemical structure, pharmacokinetics, mechanism of action, cognitive benefits, safety profile, and legal status.
By examining relevant clinical studies and the latest scientific findings, I aim to comprehensively understand Adrafinil's potential as a cognitive enhancer and its implications for various populations.
So without further ado, let's dive in, shall we?
Overview of Adrafinil as a Nootropic
Adrafinil (CRL-40028) is a synthetic eugeroic, or wakefulness-promoting agent, that was developed by French researchers in the 1970s. It belongs to a class of compounds called nootropics, which are cognitive enhancers often referred to as "smart drugs."
Nootropics are known for their potential to improve various aspects of cognitive function, including memory, attention, and mental processing speed, without causing significant side effects or dependency issues.
Adrafinil is a prodrug for Modafinil, which means that it is converted into Modafinil in the liver through a metabolic process. As a result, Adrafinil shares many of the same pharmacological effects as Modafinil, although with a slower onset of action due to the required metabolic conversion.
The primary advantage of using Adrafinil over Modafinil is its legal status and availability as an over-the-counter supplement (OTC) in many countries, including the United States. Off-label, Adrafinil has been utilized to treat various conditions, including narcolepsy, a sleep disorder characterized by excessive daytime sleepiness and sudden episodes of sleep.
It has also been explored as a potential treatment for attention deficit hyperactivity disorder (ADHD), a condition marked by inattention, hyperactivity, and impulsivity.
Moreover, Adrafinil has been used to alleviate the symptoms of shift work sleep disorder (SWSD), a circadian rhythm sleep disorder that affects individuals who work during non-traditional hours, leading to difficulties in maintaining alertness and cognitive performance during their work shifts.
In addition to its applications in treating sleep and attention disorders, Adrafinil has gained popularity among students and healthy individuals, in general, seeking to enhance their cognitive performance, especially in situations requiring increased alertness, focus, and mental stamina.

Chemical Structure and Properties
Adrafinil's chemical structure consists of a diphenylmethyl sulfinyl group attached to a hydroxyacetamide group. Its molecular formula is C15H15NO3S, with a molecular weight of 289.35 g/mol.
The compound appears as a white, crystalline powder that is soluble in organic solvents such as methanol, ethanol, and chloroform. The CAS number for Adrafinil is 63547-13-7, which serves as a unique identifier for the compound in various chemical databases.
Metabolism and Conversion to Modafinil
After oral administration, Adrafinil undergoes hepatic metabolism in the liver, where it is converted into its active metabolite, Modafinil. This biotransformation process involves two primary enzymatic reactions:
The reduction of the sulfoxide group to a sulfide group.
The hydrolysis of the amide bond.
These reactions form the pharmacologically active compound Modafinil and its inactive byproduct, modafinilic acid. The conversion to Modafinil is critical for Adrafinil's cognitive-enhancing effects, as it is Modafinil that exerts the majority of the pharmacological actions in the body.[1]
Pharmacokinetics, Half-life, and Bioavailability
Adrafinil exhibits a relatively short half-life of about 1 hour in humans. However, it should be noted that the half-life of its active metabolite, Modafinil, is considerably longer at 12-15 hours. The bioavailability of Adrafinil ranges from 50% to 80%, which means that a significant portion of the orally administered drug reaches systemic circulation and is available to exert its effects.
The absorption of Adrafinil is slow and gradual, with peak plasma concentrations reached within 1-2 hours following oral administration. This slow absorption rate contributes to the delayed onset of action when compared to Modafinil.
Adrafinil is distributed throughout the body after it is absorbed, with a stronger preference for the central nervous system (CNS), where it improves cognitive function. The kidneys get rid of the drug, primarily through urinary excretion of its metabolites, which include modafinilic acid and other minor metabolites.
The elimination of Adrafinil and its metabolites is essential for preventing drug accumulation and potential adverse effects associated with prolonged use.
Adrafinil's Mechanism of Action (MOA)
To better understand the effects of Adrafinil, it is essential to delve into its mechanism of action. Adrafinil primarily works by modulating the activity of specific neurotransmitters in the brain, affecting a range of systems that contribute to its cognitive-enhancing properties.
The primary systems influenced by Adrafinil include:
Orexinergic System
Adrafinil stimulates the release of orexin, a neuropeptide that plays a crucial role in promoting wakefulness, arousal, and vigilance. This action is achieved by activating orexin-producing neurons in the hypothalamus. As orexin levels increase, the brain's overall state of alertness and wakefulness is enhanced, leading to improved cognitive performance.[2]
Histaminergic System
Adrafinil indirectly influences the histaminergic system by increasing orexinergic activity. This interaction results in the stimulation of histamine release, a neurotransmitter involved in regulating wakefulness and arousal. The increased histamine release leads to enhanced firing of histaminergic neurons in the tuberomammillary nucleus of the hypothalamus, further promoting wakefulness and attention.[3]
Adrenergic System
Adrafinil impacts the adrenergic system by boosting the release of norepinephrine, a neurotransmitter associated with alertness, focus, and concentration. This enhancement occurs through the inhibition of norepinephrine reuptake and the activation of α1-adrenergic receptors, leading to increased availability of norepinephrine in the synaptic cleft and greater stimulation of its target receptors.[4]
Dopaminergic System
Adrafinil exerts a moderate influence on the dopaminergic system by inhibiting dopamine reuptake and promoting dopamine release. This modulation of dopamine levels contributes to improved attention, motivation, and reward-related processes, which are essential for goal-directed behavior and cognitive performance.[5]
Glutamatergic and GABAergic Systems
Adrafinil also plays a role in modulating the activity of the glutamatergic and GABAergic neurotransmitter systems. By influencing glutamate and GABA neurotransmission, Adrafinil helps establish a balanced excitation-inhibition relationship in the brain, which is critical for optimal cognitive function.
This modulation enhances learning, memory, and overall cognitive performance by fine-tuning the intricate balance between excitatory and inhibitory signaling in the brain.[6]
Cognitive Benefits of Adrafinil (Clinical Studies and Efficacy)
Now that we know the exact mechanisms behind how Adrafinil works, let's explore how it can benefit you and what that means for your cognitive performance. But before I dive into the scientific literature, it's worth pointing out that the majority of the science has been done on the related compounds Modafinil and Armodafinil.
That said, and since Adrafinil is a prodrug of Modafinil, it is reasonable to assume that these two compounds would have similar effects. In fact, several studies suggest this to be the case.
Alertness and Wakefulness
Adrafinil's stimulatory effects on the central nervous system have been shown to counteract fatigue and drowsiness in sleep-deprived individuals. Adrafinil enhances arousal and alertness by increasing the release of dopamine and norepinephrine, mitigating the cognitive impairments typically associated with sleep deprivation.[7]
Effects on Shift Work Sleep Disorder (SWSD)
Adrafinil has demonstrated efficacy in managing shift work sleep disorder, a condition characterized by excessive sleepiness and difficulty maintaining alertness during nighttime work hours. Its capacity to promote wakefulness and improve cognitive function enables individuals to better adapt to atypical work schedules.[8]
Attention and Focus
Adrafinil's influence on catecholaminergic systems modulates attentional processes, promoting sustained attention and focus. Its ability to enhance vigilance and cognitive control can improve task performance in various domains, including academic and occupational settings.[9]
Influence on Attentional Processes
Research has identified Adrafinil's impact on prefrontal cortex activity as a key factor in improving attentional processes. By increasing neuronal firing rates and modulating the release of neurotransmitters, Adrafinil facilitates the efficient allocation of cognitive resources and enables heightened focus.[10]
Improvement in Task Performance
