Before liftmode, I used different sources of phenibut, but found that their one is best good quality and it comes with lab analysis (it's important for me). Also very friendly customer service and never met in my shopping history such fast, FREE(!) shipping, I didn't believed that parcels was from them when it comes before I opened it :) and all of this comes with great prices. I'll never buy anything from different site if https://liftmode.com/ have that product in stock!
