I don't think any exist. I am not as experienced as a lot of others on this site, but I know that burning fat and gaining muscle is not as simple as taking a supplement. Depending on your goals either bulk up on muscle and then lose the fat, or lose the fat and start building up (which gaining muscle with less fat is harder) All I can say is eat a good diet and bust your ass in the gym...that is your best chance at building muscle and losing fat.
