In late January, I purchased some research items from Southern Aminos. Recently, I decided to scan the QR code provided on their items and one QR code in particular came back Page Not Found. I also checked the website that Southern Aminos uses for Certificate Of Analysis and the search also stated No items found. I sent several emails including screenshots of my findings and their response has been crickets. They’re real quick to take my money and even faster about sending out their research items , which I’m highly doubting, but really silent on responding.
