L-carnitine can be a GREAT addition to a fat loss program , but ONLY if it is an injectable version. Oral carnitine won't do jack****, as its oral bioavailability is poor. Believe me when I tell you that plenty of top bodybuilders, including pros (several of whom I know) are using injectable carnatine during prep. It works. The reason the research is so fuzzy regarding its efficacy is because oral versions are being used. That's like trying to swallow testosterone and then saying it doesn't work to build musle.
