Phenibut is a GABA derivative that crosses the blood-brain barrier and activates GABA-B receptors, which produces anxiolytic, mood-enhancing, and sleep-improving effects with significant potential for tolerance and dependence.
How to Take Phenibut
Phenibut is typically dosed at 250-1000 mg per occasion, not meant for daily use due to rapid tolerance and dependence potential, should be limited to 1-2 times weekly at most with at least 3 days between doses, and is best taken on an empty stomach for faster absorption.
