How Phenibut and GABA Work
Phenibut is unique as a supplement in that it’s classification is multi-faceted: it’s used as a nootropic (smart drug), anxiolytic (anxiety reducer), and sleep aid.
There is no one standard phenibut dosage. Doses vary between individuals due to a number of different factors, and these are discussed below.
Phenibut is modeled after GABA
Phenibut crystals are the solid form chemical derivative of gamma-aminobutyric acid (GABA), a neurotransmitter.
Many brands of phenibut are marketed as powder, which is the pure crystals ground down so they can quickly dissolve in liquid.
How GABA works at the molecular level
GABA molecules interact with the GABA receptor to open ion channels on the surface of neurons.
When neurons don’t fire, other areas of the brain also do not react. The result is an anxiolytic effect, or the perception and awareness that your mind is less reactive to stress and that that anxiety is lessening.
Various medications can trigger the release of GABA in the brain, including benzodiazepines, barbituates, and ethanol (alcohol). The GABA released from the consumption of these substances acts primarily on the GABA-A receptor.
Drugs that enhance GABA activity by interacting at post-synaptic GABA(A) receptors have long been used as hypnotics, sedatives, tranquillizers and anticonvulsants.
In this category, benzodiazepines rapidly become a favorite of doctors and patients alike, replacing barbiturates and becoming the most commonly prescribed of all drugs in the Western world in the 1970s.
However, problems such as dependence and withdrawal reactions became apparent in the 1980s, and it seemed that the usefulness of drugs with this mode of action was limited.
Recently, focus has shifted to a new group of drugs with GABA-ergic actions mediated through various mechanisms not directly involving the GABA(A) receptor.
These drugs include gabapentin, vigabatrin, tiagabine, lamotrigine, pregabalin and others.
Although originally developed as anticonvulsants for epilepsy, they appear to have wider applications for use in affective disorders, especially bipolar depression, anxiety disorders and pain conditions.
It remains to be seen whether long-term use of these leads to tolerance, dependence and withdrawal or discontinuation reactions.
Enter phenibut, an over-the-counter alternative to the heavier pharmaceuticals.
While equally as effective as the others, phenibut’s side effects are much less intense and the potential for dependance is relatively low in comparison.
Is phenibut more effective than GABA at reducing anxiety?
When taken orally, yes, it is. This might seem a bit counterintuitive – how is it that a GABA-derivative is more effective than GABA itself?
Phenibut has a higher capability of affecting brain chemistry compared to orally-ingested GABA because it can cross the blood-brain barrier, the brain’s biological shield against toxins and bacteria in the bloodstream.
Secondary effects of phenibut: sleep-aid and stress-reliever for PTSD
Because phenibut’s molecular structure is very similar to GABA, it triggers many of the same downstream physiological responses in the body.
Many users report that, in addition to its anxiolytic benefits, phenibut is tremendously helpful at inducing sleep, even in cases of extreme insomnia.
Using phenibut instills in the user feelings of well-being and happiness and it helps in fighting against insomnia, anxiety and post-traumatic stress disorder.
The 3 Main Holistic Health Benefits of Phenibut
Phenibut is commonly used as a sleeping aid and many users report its potent effects. The following reactions are reflective of the larger trend:
“Firstly Phenibut is a potent sleep aid… I have used Phenibut for a whole host of things. It realy takes the edge off of comedowns after Cocaine and MDxx.”
“…I took two large doses of Pheni during the first 8 hours of withdrawal but all those nastly symptoms never appeared and i even got 9 hours sleep my first night off the G.” – The Shaker, Bluelight.ru
“Every other nite I use phenibut and sleep well. I need something for the other nites, since you can’t take phenibut every day withou tolerance. So far, nothing comes close to making me sleep all night.” – LeanGuy, AnabolicMinds.com
The predominant paradigm is that phenibut improves the quality of sleep and leaves an amazing calming effect.
Similar to other popular cognitive enhancers like Piracetam, phenibut is beneficial for bodybuilders and strength trainers: during deep REM sleep, growth hormones are secreted which expedite muscle recovery after intense exercise.
2. Better mental performance
Research studies using mice showed that mice given higher doses of Phenibut had significantly improved reaction time as the concentration of drug increased, especially in social environments with groups of mice.
Ongoing trials are promising, showing similar effects on primate brains. The Brain Hacking community subculture has mixed reviews of phenibut, though most reviews are generally positive.
3. Feelings of Well Being
Phenibut has the ability to stimulate dopamine at low levels, which is the neurotransmitter responsible for regulating motivation and pleasure-pain cycles.
This is why phenibut users often report noticeable increases in feelings of confidence, distinct from the reduction in anxiety.
How to dose Phenibut and time ingredients
The most appropriate starting dosage of Phenibut is 250mg. The ideal dose depends on a wide variety of factors specific to the individual:
- Age is a minor contributing factor,
- Individuals with higher body weight and BMI can take higher doses
- Gender – women’s bodies react much differently to phenibut. All other variables being equal, women can take anywhere from 10% to 80% of doses taken by men for the same results.
- Previous health conditions
- Current medications
Furthermore, the purity of Phenibut varies drastically between product, brand, and company. When calibrating phenibut dosage at home, it’s best to start very low and increase the dose very incrementally over time.
