Purchase is easy but it's best to wait for a sale. They get some of their stock from Nexaph and when you compare kit prices you'll see why I say they're overpriced. For example, a kit of 24mg Reta is $738. On nexaph the same kit is $528. That's a significant markup for slapping some labels on it. You can even confirm they're the same product by pulling up the COAs on both vendors. The 5/7/26 batch COAs are the same, even the same pictures, the only difference is who the customer is. EZ has even posted COAs with Nexaph listed as the customer. Since I know they use Nexaph as a supplier I trust the majority of their product when I need an emergency single, but having the same COA as Nexaph makes you question if the COA is doctored to put their name in place. And if it's doctored, are any of their other ones doctored?
