Customer Ratings & Reviews

Rated 4.6 out of 5 by 5 reviewers.
Rated 3 out of 5 by Phenibut A few caps were empty or nearly empty. Several caps were not full as the rest of the bottle. My order arrived promptly enough and the product seems to work as well as others. April 29, 2015
Rated 5 out of 5 by Another WOW I am at an age where sleep is hard to come by. One capsule of this product, and. I am asleep within one hour. Works beautifully with no side effects. I only take phenibut 2 times a week, every 2 to 3 days, but would take more often if it was recommended (your body can adjust quickly to it). April 19, 2015
Rated 5 out of 5 by Good stuff Works great! Use only as directed. March 21, 2015
Rated 5 out of 5 by Wow! I had wanted to try this supplement that was invented in Russia, and I was so pleased to find that Swanson carried it. I hope I am allowed to say this: it made me feel good. Just don't take too much or you will be napping. Definitely don't drive if you take more than a few. Great product for the brain and mood. PS: not recommended to take too often or it will lose its effectiveness March 15, 2015
