Meso-RX is a great site for those interested in the scientific side of bodybuilding and weightlifting. Go here and read some of the outstanding articles, and dont forget to check out the message board there!

Anabolex has the best bodybuilding/weightlifting message board on the internet. Go here, sign up, and see. This is one of the few web sites I go to every single day.

A site with some good advice and interesting articles, but watch out! This site is owned by the supplement company Biotest. The really like to push their products, so you have to separate the BS from the good stuff.
