    Nurtra Synth Phenibut is by far the most consistent I’ve come across the last few years, the HCL phenibut used in these capsules are a bit different but last longer than some others found online highly recommend it. Also great customer service from this site he answered all my questions right away and shipped my order same day.

  2. Cindy Henderson

    Been ordering phenibut from for 2 years now, always consistent and never have a issue. The Nutra Synth Phenibut is better than anything I’ve tried over the years highly recommend for anxiety or stress relief.
