I ordered each of these products and they should be here in a week: wanted to get some updated info on how to use them-the latest I came across was from 2004. So which is the best way to use it to get the best results; take it orally or inject it? I've read injecting is better, but the site says for oral use only. Any feedback or links to recent(2005 or later) info would be great. Anybody used/using any of these now?
