Purchase from a company that only uses 100 % Hoodia Gordonii Succulent in a refined powder form. The main reason for this is that you have a better chance of it being genuine Hoodia Gordonii Succulent because the refined powder is easier to authenticate.

Plus the refined powder is the closest to the Hoodia Gordonii Succulent in it’s natural state. (Only water is removed from the plant before it is ground into a fine powder.)

Once you start adding other dietary ingredients with the Hoodia Gordonii refined powder the identification process gets more difficult but not impossible.
