lecithin, L-carnitine or lipo-6?

[analyzer_mike]

hye all...

i'm now at 172cm tall and 82 kg....
my body has a lot of fat especially at belly and butt...

so now i'm trying to reduce fat while gaining muscle...

so...what do i need?
Lecithin, L-Carnitine or Lipo-6?

those lecithin and carnitine turns fat into energy and lipo 6 will increase metabolism...
i'm scared that if i take the Lipo6, my body will become very thin bcoz my muscle is not really big now..still on training...

so guys...any opinion?
