Fat Burners/Energy Pills (Ripped Power)

I have been researching pills like this for awhile now. I have decided on Ripped Power. It is supposed to be the closest thing to Ripped fuel that you can get nowadays. My only question is that in researching the best place to get the pills I have found a discrepancy. On some sites the bottle pictured says" Contains ephedra extracts" , and some say " Contains Ephedra Alkaloids" I realize thta they can mean the same thing but why would a product made by the same company have different labels?
