Good Purity

Posted by 5550581264755392265 on Sep 04, 2016 | Verified Purchase

Have tried many products containing phenibut. Not all manufactures final product work the same. Some suppliers have better quality. Product handeling & end users seem to impact quality for better or worse..... Pure phenibut forms a crystal..... If end user abuses with other pharma hard drugs...Quality of crystal is decreased.... If end users workout, practice metaphysical meditation, yoga, tai chi, surfers, students, healthy diet, etc... Quality of crystal increases. Any crystal can be cleansed & purified of harsh addictive pharma crap. Keep in mind phenibut was originally used by Russian astronauts in space program.

So unreal for shift work

Posted by NightshiftPaul on Jun 07, 2016 | Verified Purchase

So good for getting proper sleep before night shift, I have tried a few things, most natural supplements just don't work and other sleep medications leave you groggy but Phenibut works so well. With Phenibut I sleep deeply yet I wake up feeling refreshed and ready for work. I take it an hour before I need to sleep on the day before my first night shift, then I take it the day after my first night shift to make sure I get a good start on that sleep pattern. At first I found it hard to gauge the dose but I bought a cheap electronic mini scale and I only ever use 250 milligrams (1/4 gram) at a time, that is heaps for me and I never take it less than 5 hours before work because it takes about an hour to kick in and it is at its strongest effect for about 4 hours after that. As for the anxiety relief side of things at 250mg I don't really notice that nor do I feel particularly more socially active but not being tired at work is a excellent mood enhancer in itself!

Sometimes works

Posted by Rena61 on Jun 02, 2016 | Verified Purchase

My husband is one of the hardest to be able to fall asleep after he wakes up from a nightly bathroom break. Strange, but sometimes it works but sometimes it doesn't. He took the pill form, and the same thing happened. He only takes a couple of times a month, so I know it's not because his body is getting too much of it. He is just that difficult of an insomniac. The taste is bitter so he says, but I get a kick out of his expression when he takes it. Evil of me I know.
