there is no such thing as a "fat burning supplement". Anything that advertises itself as such is simply out for your money. Ephedra was the closest thing to a fat burner, but to my knowledge it is banned in most plances since it is used in production of methamphetamines.
The only muscle building supplement is protein. If you have trouble putting on weight you can supplement with HMB or Bromelain which aid in protein absorbtion. The majority of supplements arent necessary for people who aren't professional athletes.
Evil will always triumph over good...
Because good is dumb.
