iv) ⚠️ Important Considerations & Warnings

Not for Daily Research

• Phenibut can build tolerance quickly and may lead to dependence if taken too frequently.

• Recommended usage: No more than 1–2 times per week, with at least 3 days between doses.

Do Not Redose

• Phenibut has a delayed onset (2–4 hours orally). Re-dosing too soon can lead to overdose symptoms including extreme sedation, motor impairment, or nausea.

• Chronic or daily use may result in physical dependence, and sudden discontinuation can lead to serious withdrawal symptoms (anxiety, insomnia, tremors, seizures in extreme cases).

• Avoid prolonged or escalating use.

CNS Depressant Warning

• Phenibut is a central nervous system depressant. Combining it with other depressants (e.g., alcohol, benzodiazepines, opioids) can be dangerous or fatal.

Not for Use with MAOIs or GABAergic Medications

• Avoid combining with medications or supplements that affect GABA, serotonin, or dopamine systems without consulting a medical professional.
