I have purchased Phenibut from several different re-sellers on the web & once I found LiftMode, I no longer went anywhere else. I never realized there would be a difference in quality of this product, but soon realized there definitely was. Not only was the product's quality so much better, but the customer service was simply outstanding. I was also extremely pleased with Liftmode's shipping speed; I actually had the product in my hands on the 3rd day after placing my order. I will definitely be a life-long customer!
