iHerb Customer Reviews

Pretty good phenibut!

Posted by Fishermanzz4 on Jan 03, 2017

Works pretty well. I love that it's tested for purity. Some brands aren't. Primaforce has been around for a bit and makes great products all together. This Phenibut definitely helps with sleep. It may not work for some people because everyone is different. But in my experience, Phenibut does tend to work. I just have to take a short break and cycle it because it'll increase the effectiveness. I would definitely start small by taking one pill and then increase gradually. It can be potent, depending on the user. Other than that, the price can't be beat! I have literally not found a better price anywhere else. Thanks iherb !!!!!

Seems to calm down and give a better sleep!

First time I buy this product and maybe it is to early to evaluate, thats why I give it only 4 stars. I will try with 2 caps when the potency not seems to be very strong and I have been used to prescription medicine for relaxation and sleep. But as always a good price and product from Iherb!

Like an milder mix of GHB and Lyrica

This works wonderfully. I suffer from depression and Phenibut gives me two extremely motivated days per week. Never exceed the recommended dosage for more than two days in a row, you will regret it. I promise.

Helps me sleep!

Posted by GrumpyMcSleepyhead on Aug 03, 2016

This product, more than any other I've tried, helps me get a solid 8 hours of uninterrupted sleep. Unfortunately, I limit my use to twice a week, on nights before my busiest days. Two capsules an hour before bedtime really does the trick. I'm flying overseas next week... we'll see how it works for jet lag.

I tried it according to the directions. The first day I took one. The second day I took two. The third day I took, and the fourth day I took four. I felt nothing but a dry mouth.
