In the last few months I have purchased a few different nootropic compounds off of liftmode.com, primarily Phenibut HCl. All of the products I've tried from them are incredibly pure, effective, clean, and safe (with responsible usage of course). The phenibut in particular is the best quality I've ever tried, I believe even better than what Nootropics Depot used to sell, and on top of that it's incredibly affordable and shipping is relatively cheap. They typically have most products stocked often, but recently they were out of stock of the 40g tub of phenibut fine crystals. They also have large crystals and array of quantities. However, I clicked a notification to alert me by email when it was restocked however that did not happen. I contacted their customer service to inquire about why that was, and they responded in a timely manner and were very polite and helpful. They helped me to make sure that doesn't happen again in the future. I was able to get another tub of the 40g fine crystals later so all's well that ends well. Anyways, this site is very reputable and their employees go above and beyond.
