According to the manufacturer, Primaforce Phenibut capsules are “lab tested for potency and purity, [and] can help support relaxation, restful sleep and feelings of well being.”
These claims are backed up by over 40 years of research history on Phenibut as well as clinical use as a psychotropic drug in Russia.
Phenibut is a modified version of GABA which is one of the neurotransmitters that your brain uses to communicate between neurons.
The role of GABA in the brain is to optimize neural activity and prevent excessive stimulation or excitation of the nervous system. GABA is released to stop neurons that are firing too quickly which is one of the characteristics of anxiety, stress, and related mood disorders.
In some instances, GABA levels may become diminished in the brain. In other cases certain individuals may be predisposed either to have lower sensitivity to GABA or a lower rate of production. In these situations it becomes important to supplement with additional GABA to alleviate anxiety, prevent panic attacks, restore normal behavior, and overcome fears or fixations.
Increasing GABA activity in the brain is observed to temper phobias or social anxiety while enabling the user to relax, calm themselves, and better control impulses. However, if you simply give someone GABA, it will not have much effect on preventing anxiety since this neurotransmitter on its own cannot penetrate the protective membrane which separates nutrients in your blood from brain tissue (blood-brain barrier).
In order to get across the blood-brain barrier, GABA must be combined with something else or modified in a particular way. This was the intent behind the development of Phenibut: by combining GABA with a phenyl ring at the molecular level, the modified compound it is able to cross over this barrier and interact directly with neural receptors.
Primaforce Phenibut is a single-ingredient product that provides pure Phenibut to stimulate GABA receptors in the brain.
The majority of the research done on Phenibut is from when the compound was first developed and used in Russia in the 1960-70s. More current research needs to be done to determine the full effects that Phenibut may have. Even though Phenibut is used today in Russia as a prescription medication for mood disorders like anxiety, at this time in the US, the FDA has not approved Phenibut as a drug to prevent or treat any conditions.

How to Safely Take Phenibut
Primaforce sells Phenibut either in large tubs of bulk powder or in vegetarian capsules (veggie caps) with 250 mg per dosage.
The capsules can be convenient for measuring out your dosage, but you will pay a significant premium for the manufacturing process that goes into encapsulating the powder.
You should also note that purchasing your supplements as capsules can mean it will take longer for them to become active in your system since the capsule or pill first has to be broken down.
Primaforce Phenibut is typically dosed in amounts between 250 mg to 1,500 mg with a maximum safe dosage of 2,000 mg has been reported by users. Exceeding this amount can dramatically increase the risk of side effects, withdrawal and tolerance, without an increase in any benefits.
Phenibut is known to have a high potential for abuse and you should always use the lowest possible effective dosage for yourself. Overdoses can lead to muscle relaxation, lower body temperatures, difficult coordinating movement (like alcohol), memory loss, and in extreme cases loss of consciousness.
Most users will only need to take this nootropic once per day because it has quite a long half-life. If you are using it as a sleeping pill, take your dosage about 2 hours before you intend to go to bed.
It is not recommended to take PrimaForce Phenibut for more than 3 consecutive days, and to leave a 2 to 3 day rest period.
If you use this supplement on an extended basis without cycling it, you can develop withdrawal symptoms that can lead to irritability, insomnia and a worsening of anxiety. You should exercise restraint by using it sparingly so that you do not develop any sort of dependence or addiction.
PrimaForce Phenibut should not be consumed in conjunction with alcohol, and it is also not suitable to be taken by children under the age of eighteen. In addition to this, high doses of the drug may inhibit a person’s ability to drive or their capability of competently operating heavy machinery.
Primaforce Phenibut Review Conclusion
One of the benefits from buying your Phenibut powder or capsules from a larger company like Primaforce is that you are guaranteed of higher quality.
According to Primaforce, they perform HPLC tests on all of their supplements for potency and purity. This is important because some companies will market fake or impure products that can be less effective and potentially dangerous.
You should note that Primaforce Phenibut is said to have a fairly unpleasant smell as well as a bitter taste so you might want to mix it in juice or some flavored drink to mask the taste.
One final thought is that Primaforce Phenibut tends to be more expensive than if you were to buy non-branded Phenibut powder from a nootropics store online. If you are looking for the best value for your money, consider purchasing bulk Primaforce Phenibut powder instead of capsules to cut down your cost per dose.
