which of thes products is best

Hi, i need to loose a stone of fat and can get hold of these supplements which ive heard all are good, vote on which gives the best results XENEDRINE, XENICAL or E,C,A or any other readily available supplements not mentioned.
I also heard clenbuterol and cytomel can be effective but have bad side effects, i can get these but would prefer to try one of the others listed above first.

Also i am using creatine by the german manufacturer reflex, its popular and claims to be one of the best but does anyone know of a better creatine?

thanks

Here is the best thing that you can do to loose your stone of fat.

Monitor what you eat
cut out junk food
eat small meals every 2-3 hours
eat 1.5grams of protein per pound of lean body mass
eat low GI carbs like oats and yams
take flax and fish oils
research Post workout Nutrition.
remember that there is not miracle supplement legal or otherwise including roids and T3 that will make up for a poor diet..

This is all i will say.
