What is Phenibut?
Phenibut (beta-phenyl-gamma-aminobutyric acid) is a derivative of GABA (gamma-aminobutyric acid). Unlike GABA, however, Phenibut can easily pass through the blood-brain barrier and bind to the GABA receptors in the brain.
Compounds that bind to GABA receptors reduce anxiety, produce euphoria, and induce sleep in high doses.
How does Phenibut work?
Phenibut binds to the GABA receptors in your brain (similar to alcohol and prescription anti-anxiety compounds).
Phenibut mimics GABA that is endogenously produced (produced within the body) by binding to GABA-B and GABA-A receptors in the brain.

How to use Phenibut?
Phenibut is generally used as a powder. You can measure it using a scale or a measuring spoon. It can be mixed into a drink (it has a very strong, unpleasant flavor) or encapsulated.
When Phenibut is encapsulated, it’s usually at 500 mg per serving.
You should follow a dosing schedule when you use Phenibut.
Upon waking up in the morning, on a completely empty stomach take 500 – 1000 mg of Phenibut. If you weigh >210 lbs take 1500mg of Phenibut. If you mix it into a drink, mix it into a zero calorie drink like tea, coffee, or diet soda.
Many users highly recommend mixing Phenibut with caffeine or another stimulant. 80 – 160 mg of caffeine is the preferred amount.
45 minutes after your first dose, you can eat some food if you are desire.
At 90 minutes to 2 hours after your Phenibut dose, evaluate how you feel. Phenibut can take long to start working in some cases, sometimes 4-5 hours. However it usually will produce noticeable effects in about 2 hours or sooner.
If you feel NOTHING after 2 hours, take another 500 – 1000 mg dose.
5 hours after your INITIAL dose, re-evaluate how you feel (and based on your plans for the rest of the day, night) consider taking 500 – 1000 mg more.
Do not exceed 2000 mg in a 24-hour period.
Short summary of Phenibut dosing schedule:
- Wake up: take 500 – 1000 mg on an empty stomach
- +2 Hours after your first dose – consider taking another 500 – 1000 mg
- +5 Hours after your first dose – consider taking another 500 – 1000 mg
- Evaluate how you feel on an hourly basis. It can take a while to kick in.
Using Phenibut for sleep: a 1000 – 2000 mg dosage taken all AT ONCE can be used for sleep.
Many users report that the sleep is incredible and extremely deep. Be aware that there may be residual drowsiness into the next day.
Classes of Phenibut
There are no “classes” of phenibut. It’s either pure phenibut, or it’s fake or adulterated.
Possible Side Effects of Phenibut
Phenibut has very few significant side effects. However caution should be used when mixing it with alcohol as it can potentiate the effects of alcohol. People have reported that 1 drink feels like 3 drinks and 3 drinks feels like 7 or 8 drinks. Use precaution and do not drive.
Although Phenibut is not addictive, tolerance does build fast. It should not be used every day. The safest protocol is to use it 1 to 2 times per week with 4 days in between each usage.
