Cortexi® is definitely not a scam.
It’s a reputable product created by an American company, and that is FDA approved.
With that said, there are dozens of imitations of Cortexi® online, and if you buy your bottles outside of the official site you run the risk of getting fake product.
Some customers have had the unfortunate luck of having bought it outside of the official site. Product owners can’t hep in these instances.
AVOID buying Cortexi® on the following sites, or you might get scammed with a fake product:
-Amazon
-Ebay
-Walgreens
-Walmart
