I was given this a while back by SJC and think that all of you guys should have a look at it. Its some of the most informative stuff I've read and answers literally hundreds of questions you might have about nutrition and bodybuilding.
In case you dont know layne is a natural bodybuilder currently doing a phd in chemistry/nutrition. This info was taken from his threads on MD and bodybuilding.com
It is very long but its easy to navigate if you use the hyperlinks at the contents page. Hopefully you guys will be able to get some good info out of it.
