Metabolife is basically ECA with Bee Pollen and Ginseng added. You'll probably as good of results from just a normal ECA stack, and it's a lot less money.. Just do a search on ECA and you'll get a ton of info on dosages and how it works. I didn't like Metabolife because of the Ginseng.. It makes me feel strange.. If you're allergic to Bee stings, you need to be cautious of taking it because of the pollen. Good luck.
