F-Phenibut Review: Effects, Dosage & Where to Buy

“Feel joyful and relaxed,” states the label on F-Phenibut.

This chemical could be the one for you if you want to feel precisely like that, with the added benefit of stomach butterflies like you’ve just been promoted at work.

Let’s see what this Fluorophenibut review has to say.

What is F-Phenibut, exactly?

F-Phenibut (Fluoro Phenibut, 4 Fluorophenyl, 4 amino 3) [R] is a GABA B receptor agonist and central nervous system depressant that is more powerful than Phenibut.

Fluorophenyl butanoic acid is a depressant that belongs to the Gabapentinoid chemical family. It has comparable calming effects to other nootropics but is five to ten times more potent, making it a feasible alternative.

Phenibut powder interacts with the central nervous system and reduces brain over-excitation levels.

Fluorophenibut has a shorter half-life in the body than Phenibut, despite the fact that it operates similarly. It’s a GABA B derivative with the added benefit of being able to pass the blood-brain barrier thanks to the phenyl ring.

The material crystallizes and is water soluble in its natural state. Its chemical structure is similar to that of Baclofen, with the exception that fluorine substitutes chlorine atoms in the para-position of the phenyl group.

What is its purpose?

Fluorophenibut is comparable to antidepressants such as gabapentin and pregabalin, but it is recommended since it is thought to inhibit excitatory neurotransmitters.


The main inhibitory neurotransmitter is GABA, or aminobutyric acid. On the one hand, Fluorophenibut, a GABA receptor agonist, is controlled, resulting in relaxing and sedating effects in the central nervous system.

Unlike Phenibut powder, there has been minimal human research on the usage of 4 Fluorophenyl, so we can only make educated guesses regarding its pharmacology and potential as a depressive.

Effects & Benefits

4 Fluorophenyl (4 amino 3) is less stimulating and has a quicker onset than other nootropics. When the voltage-gated calcium channels are overstimulated, the correct quantity of depressant may help you relax.

According to studies, the appropriate amount provides beneficial physical and cognitive advantages.

  • Sedation. It may promote sleep and provide the sense of being completely rested when taken in tiny quantities.
  • Wakefulness. A greater dosage, on the other hand, stimulates the brain, increasing productivity and mental alertness.
  • Euphoria is a feeling of happiness. This sensation of pleasure is comparable to that experienced when one is excited or in love. While the medicine is in action, it may reduce anxiety and make you feel happy.
  • Appetite stimulation. A person’s appetite is stimulated at the correct dosage, resulting in increased food intake.
  • Entactogenic properties Moderate dosages may boost friendliness and empathy, lowering social inhibitions and increasing emotional openness.

How long does it take for you to notice it?

Other nootropics take a long to start working, while 4 Fluorophenyl takes just 20 minutes. Others may take up to 60 minutes before they see a change.

Within 6 to 8 hours, the impact is noticeable.

Dosage & How to Take

Although there isn’t enough study to determine the suggested amount, it’s preferable to start with lesser doses to allow the body to acclimate to the effects.

The threshold dosage is 50 mg, with light doses ranging from 100 to 150 mg. Users that testified about this substance said that 250 mg to 400 mg is all they need to experience the benefits.

The strong dosage is from 400 to 600 mg, while the heavy dose ranges from 600 to 100 mg.

Keep a 4-hour interval between doses and increase it every two weeks of daily ingestion.

If you’re pregnant or breastfeeding, talk to your doctor before taking this or any other nootropic.

Because there isn’t enough study on the product yet, the advised dosages are only guesses from prior users.
