Strong and effective

Posted by 5092191231816312200 on Apr 26, 2014

This is the only supplement I've found that will actually put me to sleep. I have chronic insomnia and used to be on benzos to treat it. They worked for me but caused awful withdrawal and addiction issues. I have been looking for a herbal remedy since going off those nasty benzos months ago. I have tried so many things and phenibut has worked the best. The problem lies in my days off phenibut, I have a hard time sleeping & so I can see how dependency could develop even with this supplement. So just be careful as it's quite strong. A couple benedryl and valerian seem to help sometimes on 'off' days.

Turned into a scam

Posted by 5548670463636660239 on Feb 10, 2014

I used to be a real fan of this supplement, it seemed to work for me, but it has since turned into a scam. I was wondering what they'd do as they the supply couldn't meet the demand, and 'Primaforce' were often out of this product. Their answer was to reduce the size of their capsules over the last 4 months, and still claim they were shipping 250mg.

Been using this product for about three months now. I got to say, that it delivered everything promised and more. My anxiety is gone. No need for bentsos and other Rx products anymore. This is potent GABA-agonist, so be aware of tolerance build up. 5/5!

Overall, worth it for sleep and anxiety

Posted by 5146659032863549230 on Jun 26, 2013

The Phenibut can be very long lasting. It does have wicked side effects for me in that it affects my memory for 1-2 days after taking it. I become very absent minded. Again, it mostly affects my mind instead of my body like Xanax does. But it does help my anxiety and helps me sleep, which are the important things.
