I have purchased multiple items from liftmode.com within the last couple of months finding what works best for me. Overall quality control seems on point and always get certificates of analysis with product - phenibut is amazing, theanine is great, noopept is great, and phenylpiracetam is also great. I have tried other vendors such as powdercity who I have received a chunky batch of powder before - so far liftmode has been flawless and is my go-to for available powders. I do wish they supplied adrafanil. I will continue to recommend and purchase from - professionally packaged, shipping is prompt and tracking information provided quickly - they also provide recommend dosage information and scoops to help get you there. Give them a try!
