Metabolife and i used to be friends...and it was good...until my body got used to the dosage. if you ever take these, you have to up the dosage every once in a while to keep yourself from getting hungry etc. (i went from half a pill a day to 2 pills a day), and if you ever get off of them, well! Have fun with that! Because youll have ZERO energy. Its awful. Dont try them. Period.
