Not sure if these have been posted lately but I didn't see much about them when I ran a search. Click the italic name to open the link:

Ergo-log.com

There is a huge archive of published studies regarding all types of health, fitness, supplements, etc. It's updated almost everyday, makes for a good research tool.

LabDoor.com

Independent lab tests on a lot of supplements, it's free to sign up and to me it's worth it because you can read a more in depth review of each product tested. Not sure how often it's updated but you can vote on which supplements you want to see tested. I think the one with the most votes for the month goes for testing, not sure if that's exactly how it goes but it's something like that.

I'm not affiliated with either of these sites lol, but when I find something useful I like to share ;-P
If anyone has any similar sites like these (or anabolic lab), post 'em up!
