The problem is that it's really tough to know which companies to trust. There are companies that will post counterfeit CITES certificates -- Convention on International Trade in Endangered Species of Wild Fauna and Flora, a document required to sell hoodia and verify that it has been obtained through legal channels. They can fake the lab tests by submitting a genuine batch for approval and then replacing it with adulterated material in the actual production run. They can steal CITES certificates from other companies and then use Photoshop to replace the company name.
There's even evidence now that some companies are using soluble material to cut their product in a way that is difficult to detect in laboratory testing. Hoodia thin supplement retailers and sellers are certainly coming up with very creative ways to keep selling the counterfeit product without anyone knowing.thin
But whether it's real or not is really only one part of the question concerning hoodia. As I've said, my estimate is that 80 percent of the hoodia being sold today contains no genuine hoodia gordonii. Not all the people selling hoodia are crooks.
