b-12 or l-carnitine?

there have been lots of threads about b-12 lately, how it helps out with stimulating appetite. i was wondering if it helps burn fat also.....and if it does would you recommend that over l-carnitine. i haven't even really heard about too many people using injectable l-carnitine for fat burning properties, so if anybody out there has tried it i'd be interested to know how it went. thanks.

Send me a message for questions about the success that I've had with injectable L-carnitine. It's working for me.
